Abstract (en)

[origin: WO9618079A1] A proximity fuse for initiating detonation of the effective part of a robot, comprising a passive unit is described. It includes a first antenna means (1) for receiving electromagnetic radiation within the microwave range, having a relatively narrow first antenna lobe, and a second antenna means (2) for receiving electromagnetic radiation within the microwave range, having a second, relatively broad antenna lobe, that encloses the first antenna lobe, the first and second antenna lobes preferably being rotationally symmetric in the roll direction of the robot. The proximity fuse comprises electronic components and circuits (3-8, 10, 11) for detecting a first signal S1 from the first antenna lobe and a second signal S2 from the second antenna lobe and a first means (9) for issuing a third signal S3 for initiating a detonation of said effective part. It is in particular characterized in that the proximity fuse is arranged to issue the third signal S3 in the case where the following conditions are simultaneously satisfied: a) the quotient Z of the amplitude A1 of the signal S1 and the amplitude A2 of the signal S2 exceeds a first value Z1 determined in advance, i.e. that Z = A1/A2 > Z1, and b) the time derivative dZ/dt exceeds a second value Z2 determined in advance, i.e. dZ/dt > Z2.
