摘要	PURPOSE:To attain to enhance shoot-down power of a target by preventing the narrowing of a detection effective range to a low altitude target, by performing control so as to make the target detecting distance of an upper side antenna receiving no influence of clutter constant. CONSTITUTION:A demodulation part 21 sends out a warhead demodulation signal on the basis of a signal through an antenna 7 and a circulator 5 and a warhead gate signal from a setting part 20. A detection circuit 22 judges whether the distance from the warhead demodulation signal to a target 10 is present in the inside or outside with respect to the warhead effective range always set constantly and, in the case of the outside, outputs a low level signal and, in the inside, outputs a high level signal. An OR circuit 23 outputs a low level signal when the outputs of the detection circuit 22 and a detection circuit 18 for detecting the invasion of the target in the target detection effective distance are together a low level. Therefore, even if the distance between clutters are invaded into the warhead effective distance of an active proximity fuse N', the detection distance of a lower side antenna 8 is short and the detection distance of an upper side antenna 7 always keeps the warhead effective distance.
