摘要	PURPOSE:To prevent the activation of a detonation signal due to a clutter signal generated from the ground surface or the sea surface by receiving a signal from a target accurately with a narrow band filter changed in the center frequency of a Doppler amplifier according to the speed of the target. CONSTITUTION:As a target airplane comes into a beam of an antenna 1, a Doppler signal is produced with a Doppler deviation in the beam proportional to the relative speed between the guided flying body and the target airplane as same with a reflected wave from the ground surface or the sea surface and enters a Doppler amplifier 7. The Doppler amplifier 7 is provided with a narrow band filter varying in the center frequency according to changes in the frequency of the Doppler signal of a Doppler tracking device 6 and can capture a signal from the target airplane accurately. Outputs of the Doppler amplifier 7 and a clutter amplifier 8 enter a detector 9 provided with threshold for the generation of a detonation signal. The threshold of the detector 9 is determined by the output of the clutter amplifier 8 for amplifying clutters. As exceeding the threshold of the detector 9, the output is provided to a detonation circuit 10 to trigger a warhead 11.
