<p>PROBLEM TO BE SOLVED: To solve the problem of tracking errors which occur due to distance deviations superposed on an observation value caused by the approach speed of a target in the case of using frequency modulation for transmission waves in a radar for detecting and tracking an air target. SOLUTION: In the radar for detecting and tracking an air target through the use of frequency modulation for transmission waves, the approach speed of the target is computed from the amplitude differences among target detection signals after demodulation by a plurality of demodulation reference signals to correct an observation distance.</p> |
