<p>PROBLEM TO BE SOLVED: To provide the radar signal processor in which a stable target detection rate is obtained by varying the constant false alarm rate(CFAR) system and the parameters against the input signals that are varying by the constantly changing clutter conditions and the hit differences of the beam direction. SOLUTION: In the radar signal processor, any one of clutter suppressing circuits 2, 3 and 4 located in a clutter suppressing circuit group 5 is selected by a selection switch 6 and the inputted signals are processed for clutter suppression. A selection switch 8 selects an optimum CFAR, which is matched with the amplitude distribution of the clutter suppression processed signals, from a CFAR circuit group 9 and the CFAR is applied to the signals.</p> |
