Radar range equation is useful to know the range of the target theoretically. Now, let us solve a few problems by using those equations. Use eqn 23 the maximum unambiguous range is 12 the distance that can be travelled by the radar energy during the time of one sweep from 400 to 800 mhz. R is the range from the radar to the target and has the units of meters.

Radar scans threedimensional space to gather information about detected objects such as location, shape and speed. Pdf this paper deals with the minimum detection range versus maximum. In this section the radar equation is derived from the oneway equation transmitter to receiver which is then extended to. Given the mds, the maximum detection range can be obtained. Calculate the maximum range of radar for the following specifications peak power. Maximum unambiguous range a problem with pulsed radars and range measurement is how to unambiguously determine the range to the target if the target returns a strong echo. Signal to noise ratio sn or snr is the standard measure of a radar s ability to detect a given target at a given range from the radar. In this chapter, we will discuss the standard form of radar range equation and then will discuss about the two modified forms of radar range equation.
