(Appendix 2) Explanation of system parameters
Parameters related to the operation of this system can be set from the screen.
These parameters are described below.
１．Parameter setting 1
No. Name Description
1 Limit sensor upper end The angle from the upper limit sensor position to the horizontal
position in the tilt motion is expressed as the product of the motor
moving step number (3000) and the gear ratio (19). One tilt rotation
(360 °) corresponds to 57 thousand steps.
2 Tilt speed (RPM) The speed of the tilt motor is expressed in rpm.
3 Tilt acceleration (Rev / s
2
) The tilt motor acceleration is expressed as Rev / s
2
.
4 Digital filter proportional term This is the proportional term of the digital filter of the tilt motor.
5 Digital filter integral term This is the integral term of the digital filter of the tilt motor.
6 Overshoot upper end As the upper end of the movement range in the tilt motion, the angle
from the horizontal position is expressed by the number of moving
steps of the motor. One tilt rotation (360 °) corresponds to 57
thousand steps.
7 Overshoot lower end As the lower end of the movement range in the tilt motion, the angle
from the horizontal position is expressed by the number of moving
steps of the motor.One tilt rotation (360 °) corresponds to 57 thousand
steps.
8 Measurement upper end As the upper end of the measurement range in the tilt motion, the
angle from the horizontal position is expressed by the encoder step
number.
One encoder revolution (360 °) corresponds to 8192 steps.
9 Measurement bottom end
position
As the lower end of the measurement range in the tilt motion, the angle
from the horizontal position is expressed by the encoder step number.
One encoder revolution (360 °) corresponds to 8192 steps.
10 0 m Point correction value This is an adjustment value to adjust the measurement distance.
11 sampling resolution (m)
This represents discrete value of the sampling distance.
12 I Signal offset This is an offset adjustment value for I signal. (It is normally 0)
13 Q signal offset This is an offset adjustment value for the Q signal. (It is normally 0)
14 ADC input impedance Indicates the input impedance of the A / D converter.
15 ADC full-scale voltage This is the voltage range of the A / D converter used in this device.
16 Antenna attenuation loss This represents the attenuation loss value of the antenna.
17 Measurement time interval If it is necessary to keep the measurement interval constant, specify
the repetition time of measuring one image longer than the actual
measurement time.
If the specified measurement interval is shorter than the actual
measurement time, the latter is applied.
２．Parameter Setting 2 (Setting of turning motor)
No. Name Description
1
Measurement start delay time
This is the delay time from the heading sensor detection in the
turning direction to the start of data acquisition. (It is a unit of μ
