4.6 Data acquisition

Once you are sure all the scan parameters have been correctly defined, you are

ready to start.

Press the

button in the window shown in Fig. 4-27 and

start to move the trolley along the desired path (always in the same

direction). The results of the single sections will start to appear in real time

on the monitor in a window dedicated to channel 1 (see Fig. 4-31). The

active channel is indicated with a red box in the sweep window. When a

window is completely filled, the data will be written over from left to right

and you will notice that the content of the radar section changes line by

line. When the system passes across a possible utility or a radar target of

any type, typical hyperbola shaped figures will appear with variable

contrast in the depth direction corresponding to the impulses received. The

presence of targets can be detected by comparing these figures, window by

window, however, it is easier to perform this operation during the

processing phase. The distance travelled by the trolley (

Distance:….m

) is

shown above the radar map in real time, the depth is expressed in meters

(

) on the left y axis while the time delay expressed in nanoseconds (

) is

given on the right y axis as indicated in Fig. 4-31. To visualize another

acquired channel in real time, you can click on the small window of the

signal corresponding to the desired channel.
