<p>PROBLEM TO BE SOLVED: To ensure automatic ON/OFF of clutter suppressing function by additionally providing an amplitude detector, clutter level detector, and clutter suppression controller. SOLUTION: A radar reception video signal output from an A/D converter 9 is input to an amplitude detector 26, and converter into an amplitude signal. When the amplitude signal is input to a clutter level detector 27 and a specified amplitude level or above is detected, it is determined that clutter exists, and base on the result, it is controlled to bypass a digital filter 10 by a clutter suppression controller 28.</p> |
