2. RADAR OBSERVATION

2.3.2 Showing SART marks on the radar display
This radar is equipped with a feature which optimally sets up the radar for SART
detection. This feature automatically detunes the radar receiver out of its best
tuning condition. This erases or weakens all normal radar echoes, but the SART
marks are not erased because the SART response signal scans over all
frequencies in the 9 GHz band. When the radar approaches the SART in
operation, the SART marks will enlarge to large arcs, blurring a large part of the
screen.
To set up for SART detection do the following:
1. Roll the trackball to choose the MENU box and then push the wheel or the
left button.
2. Roll the wheel to choose 1 ECHO and then push the wheel or the left button.
