<p>PURPOSE:To improve the signal to clutter ratio to a specific target body; by varying the frequency of a sent pulse train at intervals of (n) pulses and varying the radiation condition of a main beam with time corresponding to an integration time. CONSTITUTION:A sent pulse signal with a pulse repetition period is outputted from a transmission part 5 with a specific timing signal sent from a time control part 7, and outputted to a specific investigation space with main beams from a transmission/reception switch part 4 and an antenna 1. Further, a main beam control part 2 controls radiation characteristics of a main beam radiated from an antenna part 1 with time with a specific timing signal sent from the control part 7. Then, a reflected signal from a specific target body such as a peripheral fixed reflector is inputted to a reception part 6 through the antenna part 1 and switch part 4, and demodulated by the reception part 6 and inputted to a signal processing part 8, which performs non-coherent integral processing for the received signal which are inputted at an integration time and detected with the specific timing signal inputted from the control part 7, so that the received signal is outputted after the non-coherent integration processing.</p> |
