Abstract
The proximity fuse is incorporated in a warhead carried by a missile. This warhead comprises several active or passive bodies, which consist of preformed splinters or shaped charges. The proximity fuse comprises a circuit for producing an ignition signal to start the decomposition of the warhead when a distance is reached between the warhead and a target, for instance a missile. This distance is determined by using electromagnetic waves. The circuit comprises means for determining the time t.sub.A, which will elapse before the warhead encounters the target. Moreover, the circuit comprises means for storing a constant reference time t.sub.B, which is fixed in such a way that the active or passive bodies released within a certain space sector when the warhead decomposes, will be scattered in a certain space, i.e. they will cover this space in front of the target within this reference time. The circuit also comprises means for comparing the calculated time with the constant reference time being provided. The ignition signal for starting the decomposition of the warhead is released on the strength of this comparison as soon as the calculated time becomes shorter than the reference time…
