Section 4 Range and Bearing Measurement Methods  4-2 
4.2  Target Position 
The radar transmits the pulse-modulated radio waves. The transmitted waves are received in the 
target after being reflected (echoed).  On the screen, the waves spread in the pulse width range 
direction based on the target position as the front edge.   
When measuring a target or setting a mark/line on the target, place the cursor on the front edge of the 
echo.
