4.2 MEASUREMENT OF RANGE AND
BEARING
Target position on the RADAR screen
RADAR antenna transmits pulses of radio waves. The object returns the wave (radar echo) to the
antenna.
So on the RADAR screen the leading edge of echo is the actual target position.
The length of echo is dependent on the transmitted pulse length.
Point the cursor to the leading edge of echo to measure the target range or to make a mark on the
target.
