ABSTRACT:
A proximity fuse for an artillery projectile of the type having reduced aerodynamic resistance of the base. The fuse comprises a radar arrangement (1,2,3,4) which supplies a beat signal (S.sub.e) to a first chain for activating the trigger device (9) at the end of a time t.sub.1 after S.sub.e has exceeded a given threshold. The fuse also comprises a supplementary chain for counteracting the effect of air resistance, which presents characteristics of cut off (32), of amplification (33) and of exceeding a threshold (35,36) comparable with those of the first chain, of which the output signal is transmitted to inhibition means (47,48,49,41,39 and 44, 38 and 43) and which comprises first and second delaying means (34).
