Abstract

PURPOSE:To enable to detect moving objective in the clutter with a simple constitution accurately, by picking up the doppler frequency greater in amplitude from the reception signal and identifying the condition of arrangement. CONSTITUTION:The rader pulse is transmitted 1, the reflection signal from the objective is received and detected 5, the detection output is A/D-converted 6. Fourier transformation 7 is made by every same distance and a plurality of signals in connection with azimuth, and different output is delivered by every different frequency component. Further, each output signal is detected 8, each detected output is detected 9 in the order of greater amplitude, correlativity 9 is taken to this detected output for same azimuth and direction or same distance and azimuth sequentially, and the moving objective based on the result of correlativity can be displayed 11.
