WebThe minimum range, in yards, at which a target can be detected is determined using the following formula (pulse width and recovery time are expressed in microseconds or fractions of microseconds): For example, minimum range for a radar system with a pulse width of 25 microseconds and a recovery time of 0.1 microseconds is figured as follows: Webradar will set up a bank of contiguous range bins* and test for detection in each bin, thereby providing a measurement of range. Numerous signal processing techniques are available to refine the measurement to within fractions of a range bin. Also, one range bin may be constructed, where its position in range is scanned over the minimum and ...
