<p>PROBLEM TO BE SOLVED: To constitute a signal processor of large range-side-lobe suppression effect, using a simple pulse compressor. SOLUTION: A reception signal pulse-compressed at a pulse compressor 10 is outputted to a range-side-lobe suppressor 11, and at an auxiliary reception signal generator 104, multiplied by a multiplier Y which is set by a multiplier factor setting device 103 in advance. At a shift processor 105, the reception signal after the pulse-compression under goes a shift process. The outputs of the shift processor 105 are added together at an adder 106, which is subtracted from the output of the reception signal generator 104 with a subtractor 107, which is taken as the output of the range-side-lobe suppressor 11. The output of the range-side-lobe suppressor 11 is inputted in an amplitude correction device 12, and multiplied by a correction factor W obtained from the attenuation amount of a min lobe in the process with the side-lobe-suppressor 11 at an amplitude value generator 109, for output correction of the range-side-lobe suppressor 11.</p> |
