<p><P>PROBLEM TO BE SOLVED: To provide a radar signal processing apparatus that has a variable capability of detecting a target in accordance with a target detection condition, and detects a smaller target which cannot be detected by ordinary detection processing. <P>SOLUTION: The radar signal processing apparatus includes: a receiving unit 2 for receiving a reception signal reflected by a target and for output of reception data; an integral unit 3 including an FFT unit 31 for performing integral processing on the reception data and for output of integral data, a present result retaining unit 32 and a previous result retaining unit 33 for storing the integral data, a phase matching unit 34 and an addition unit 35 for calculating new integral data in response to an additional integral request; a detection unit 4 for detecting the peak position of the integral data and for output of it together with the integral data, a condition calculation unit 5 for calculating at least either one of the distance to the object and the relative speed with the target on the basis of the peak position and the integral data; and an additional integral decision unit 6 for output of an additional integral request to the integral unit 3 when the number of peak positions detected by the detection unit 4 is less than a predetermined value. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
