1.8 Radar Introduction
A radar system operates in the microwave part of the radio frequency (RF) range. The
radar detects the position and movement of objects. Objects are shown on the radar
display at their measured distances and bearings in intensities according to echo
strength.
The radar display is available in head-up and north-up modes.
A guard zone tells you when the radar targets are in the area you indicate. The trail of
targets can be shown in afterglow to monitor their movements.
The dual range display scans and displays two different radar ranges at the same
time. This display lets you watch on both short and long ranges at the same time.
Note: Dual range display is not available with the DRS4DL radar sensor.
