USAGE OF ARPA Attention l There are the following limitations on use of the target acquisition and tracking functions of ARPA. [I] Resolution between adjacent targets and swapping during automatic tracking Depending on the particular distance and echo size, resolution between adjacent targets during automatic tracking usually ranges somewhere between 0.03 to 0.05 nm. If multiple targets approach each other, resolution will become about 0.
5.1 PREPARATION This section explains the features of EPA/ATA/ARPA and AIS functions, and the initial setting for using each function. The four plotting functions below are available with this radar equipment. An optional device is necessary for using each of the ATA, ARPA, and AIS functions. EPA (Electronic Plotting Aid) function The EPA function calculates the course and speed of a target from the positions of the target that have been entered manually at specified intervals.
Attention l The menu display is changed to “ATA” or “ARPA” according to option provided in this radar equipment. Where the ARPA option is provided, the ARPA Setting is displayed in the menu. Also where the ATA option is provided, the ATA Setting is displayed in the menu. This manual basically displays using “ATA”.
5.1 PREPARATION 5.1.1 Collision Avoidance Problems of Collision Avoidance in Navigation Marine collision avoidance is one of the problems that have been recognized from of old. Now, it will be described briefly who the collision avoidance is positioned among the navigational aid problems.
Basic Concept of Collision Avoidance There are two aspects in collision avoidance: collision prediction and avoidance. Collision prediction is to predict that two or more vessels will happen to occupy the same point at the same time, while collision avoidance is to maneuver vessels not to occupy the same point at the same time. In practical operation of vessels, a spot of collision has to be deemed to be a single point but a closed zone.
5.1 PREPARATION 5 Fig. 5-3 Relative Vector and True vector Radar and Collision Avoidance Radar is still playing an important roll for collision prevention and positioning. A plotter is used to further enhance the radar functionality. The plotter is capable of plotting other positions of other ships in 3 to 6 minute intervals to monitor their movement.
5.1.2 Definitions of Symbols Types and Definitions of EPA, ATA, and ARPA Symbols Vector/Symbol Definition Remarks Safe target Alarm characters (CPA/TCPA) appear and an alarm sounds. The vector and symbol blinks with red lamp. Dangerous target Target for which numeric data is displayed M U When numeric data is displayed, the target symbol is changed into □. Initial acquisition mark (EPA) This symbol is displayed when the first plotting is performed.
5.1 PREPARATION Types and Definitions of AIS Symbols Vector/Symbol Definition Remarks Sleeping target This symbol is displayed when received data is valid. The direction of the triangle’s vertex indicates the target’s bow or COG. Activated target The heading direction is displayed with a solid line, and the COG vector is displayed with a dotted line. The line perpendicular to the heading direction indicates the direction to which the course is to be changed. This line may not be displayed.
5.1.3 Setting Collision Decision Criteria (CPA/TCPA Limit) For details on each operation, see 3.4 BASIC OPERATION and 4 MEASUREMENT OF RANGE AND BEARING. Attention l Set the optimum values of collision decision conditions, depending upon vessel type, water area, weather and oceanographic conditions. (For the relations between those conditions and alarms, refer to section 5.3.6 Alarm Display. ) Set and check collision decision criteria before operating the ARPA system.

5.3 ATA/ARPA OPERATION This section explains how to use the ATA and ARPA functions. Each function is available only when the ATA or ARPA option is installed. The functions automatically track a target, and store/display vectors as the course and speed. They calculate CPA and TCPA, and issue an alarm. The basic operations of ATA and ARPA are the same, but available functions are different. The ATA function can track up to 30 ships; the ARPA function can track up to 100 ships.
5.3 ATA/ARPA OPERATION Manual Acquisition [MANUAL] Attention l If more targets are acquired manually in the condition that the maximum number of targets are under tracking, the targets under tracking will be cancelled in the order of lower level of danger in order to track the manually acquired targets. Procedures 1 Move the cross cursor mark onto the target to be acquired, and press the [ACQ] key. The target will be acquired.
5.3.2 Canceling Unwanted Targets Unwanted targets can be canceled one by one in the following cases: · Tracking is no longer necessary for targets with which vectors/symbols are displayed after being acquired and tracked. · The number of vectors on the radar display needs to be reduced for easy observation. When targets are to be re-acquired from the beginning, all the current vectors can also be canceled.
5.3 ATA/ARPA OPERATION 5.3.3 Displaying Target ID No. (Target Number Display) A target ID number is a value displayed beside the acquisition symbol when a target is acquired. ID numbers are assigned to targets in acquisition order. When the ATA function is used, ID numbers 1 to 30 are automatically assigned. When the ARPA function is used, ID numbers 1 to 100 are automatically assigned. Each target is identified by the assigned ID number until it is lost or its acquisition is canceled.
5.3.4 ATA/ARPA Data Display (Refer to Example of Display in page 2-1. ) Display of Vectors Attention l When a target or own ship changes a course, or when a target is acquired, its vector may not reach a given level of accuracy until three minutes or more has passed after such course change or target acquisition. Even if three minutes or more has passed, the vector may include an error depending upon the tracking conditions.
5.3 ATA/ARPA OPERATION Relative Vector Mode In displaying the relative vector of a target, press the [VECT R/T] key to select the Relative Vector mode. The relative vector does not represent the true motion of the target, but its relative relation with own ship. This means that a target with its relative vector directed to own ship (passing through the CPA LIMIT ring) will be a dangerous target. In the Relative Vector mode, it can be seen at a glance where the CPA LIMIT of the dangerous target is.
[II] Vector Length: VECTOR TIME The vector length of a target is proportional to its speed, and the vector time can be switched in a range of 1 to 60 minutes by used for ten-key. The diagram below illustrates a vector length of a target for six minutes, and the tip of the vector represents the target’s position expected to reach six minutes later.

5.3 ATA/ARPA OPERATION 5.3.6 Alarm Display The ATA/ARPA system provides the following alarms: Dangerous target alarm: CPA/TCPA Guard zone entry alarm: GZ Lost target alarm: LOST System function alarm: ARPA (DATA) Gyro set alarm: SET GYRO Dangerous Target Alarm CAUTION Since these alarms may include some errors depending on the target tracking conditions, the navigation officer himself should make the final decision for ship operations such as collision avoidance.
Guard Zone Alarm CAUTION In setting a guard zone, it is necessary to adjust the gain, sea clutter suppression and rain/snow clutter suppression to ensure that target echoes are displayed in the optimum conditions. No guard zone alarms will be issued for targets undetected by the radar, and this may cause accidents such as collisions. The guard zone functions are to set a zone at an arbitrary range and to deliver an alarm if any target intrudes within this zone.
5.3 ATA/ARPA OPERATION Lost Target Alarm Attention l If the gain, sea clutter suppression, rain/snow clutter suppression are not adjusted adequately, the lost target alarm may be easily generated. So such adjustments should be mad carefully. When it is impossible to continue tracking any acquired and tracked target, the LOST target alarm will be generated. The typical causes for alarm generation are shown below, but not limited to the following: · The target echo is very weak.
System Function Alarm When an abnormal state of an input signal or a trouble in the processing circuitry occurs, an character or alarm is generated. When an alarm occurs against any ARPA function, ARPA (DATA) will appear in the WARNING display area, but no indication is made in the ARPA information display. This status means that there is any operational trouble in the ARPA system. Please, contact the service depot or the manufactures.
5.3 ATA/ARPA OPERATION 5.3.7 Trial Maneuvering (Trial) Attention l Trial maneuvering is to simulate own ship’s course and speed in the conditions that the course and speed of a target ship are unchanged as they are. As the situation is different from any actual ship maneuvering, set values with large margins to CPA Limit and TCPA Limit. Attention: Trial maneuvering can be done only when the ARPA option is installed. unavailable if the ATA option is installed.
Trial Maneuvering in the True Vector Mode In the True Vector mode, calculations are performed according to the values set by Trial Speed and Trial Course, and the result is displayed as a bold-line that represents the change of own ship’s vector as shown in the figure below (an example of the course changed to the right). In this figure, the dangerous target forward right becomes safe as a result of simulation.
5.3 ATA/ARPA OPERATION Trial Maneuvering in the Relative Vector Mode The result of Trial maneuvering in the Relative Vector mode is shown by a change in target vector. In the figure below (in the same conditions as in the True Vector mode in the previous page), it is seen that the acquired target is a dangerous one because its vector is crossing the CPA RING.

SECTION 6 TRUE AND FALSE ECHOES ON DISPLAY 6.1 6.2 6.3 6.4 6.5 Radar Wave with the Horizon....................6-2 Strength of Reflection from the Targets ..6-4 Sea Clutters ................................................6-5 False Echoes ..............................................6-6 Display of Radar Transponder (SART).....
The radar operator has a role of interpreting the radar displays to provide his best aid in maneuvering the ship. For this purpose, the operator has to observe the radar displays after fully understanding the advantages and disadvantages that the radar has. For better interpretation of radar display, it is important to gain more experiences by operating the radar equipment in fair weathers and comparing the target ships watched with the naked eyes and their echoes on the radar display.
6.1 RADAR WAVE WITH THE HORIZON Radar beam radiation has the nature of propagating nearly along the curved surface of the earth. The propagation varies with the property of the air layer through which the radar beam propagates. In the normal propagation, the distance (D) of the radar wave to the horizon is approximately 10% longer than the distance to the optical horizon. The distance (D) is given by the following formula: D=2.
D (nm) Height of Radar Scanner Detective Range Height of Target Figure 6.1 When the height of own ship’s scanner is 10 m for instance, (a) A target that can be detected at the radar range of 64 nm on the radar display is required to have a height of 660 m or more. (b) If the height of a target is 10 m, the radar range has to be approx. 15 nm.
6.2 STRENGTH OF REFLECTION FROM THE TARGET The signal intensity reflected from a target depends not only on the height and size of the target but also on its material and shape. The echo intensity from a higher and larger target is not always higher in general. In particular, the echo from a coast line is affected by the geographic conditions of the coast. If the coast has a very gentle slop, the echo from a mountain of the inland appears on the radar display.
6.3 SEA CLUTTERS When the sea surface ruffles, bright echo returns spread around the center of the radar display. The higher the waves are, the echo returns are larger. Swirling currents may appear as a smooth line like a coastal line.
6.4 FALSE ECHOES The radar observer may be embarrassed with some echoes that do not exist actually. appear by the following causes that are well known: [I] These false echoes Shadow When the radar scanner is installed near a funnel or mast, the echo of a target that exists in the direction of the funnel or mast cannot appear on the radar display because the radar beam is reflected on the funnel or mast.
[IV] False Echo by Multiple Reflection When there is a large structure or ship with a high vertical surface near own ship as shown in Figure 6.5, multiple refection returns may appear on the radar display. These echoes appear in the same intervals, of which the nearest echo is the true echo of the target. Figure 6.
6.4 FALSE ECHOES [VI] Radar Interference When another radar equipment using the same frequency band as that on own ship is near own ship, a radar interference pattern may appear on the radar display. This interference pattern consists of a number of spots which appear in various forms. In many cases, these spots do not always appear at the same places, so that they can be discriminated from the target echoes. (See Figure 6.6) Figure 6.
6.5 DISPLAY OF RADAR TRANSPONDER (SART) The SART (Search and rescue Radar Transponder) is a survival device authorized by the GMDSS (Global Maritime Distress and Safety System), which is used for locating survivors in case that a distress accident occurs at sea. The SART is designed to operate in the 9 GHz frequency band.
6.4 FALSE ECHOES With the SART display mode set to ON, settings as shown below are made automatically.
