DE3501268C1 - Fuzing sensor for fast missiles and projectiles - Google Patents

Abstract

The invention relates to a fuzing sensor for fast missiles and projectiles for detection of a hit and discrimination against impacting small-calibre defence projectiles, unambiguous initiation of the fuzing being brought about, even in the case of light target structures, by evaluating the plasma formation which occurs on impact and the electromagnetic effects associated therewith. Exemplary embodiments are specified and explained in the description.

brings. Here, the coils 12 have a diameter of Vio of the warhead diameter. To optimize of the ignition sensor, it is proposed to combine both electrodes 11 and coils 12 with one another, as shown in FIG. 1 is illustrated.

In one embodiment according to FIG. 3 illustrates how, in an advantageous embodiment, both components, that is to say electrodes 11 and coils 12 are integrated in a surface protection layer 13.

To this end, all so far for missiles and projectiles used surface protective layers are used.

The above-described plasma ignition sensor is only against if there is discrimination against bombardment sensitive to an electromagnetic pulse from nuclear explosions. However, one of the previously known Blockages of the sensor up to the target area provide protection, since then the activation is removed is uncritical from the target and can be advanced sufficiently.

Another embodiment of the invention provides a coincidence circuit of the proposed ignition sensor with an optical sensor for the plasma flash before and in another embodiment the problem becomes released by a coincidence circuit with the shock from the impact on the target. In the first case speaks one from a plasma optics sensor and in the second case from a plasma shock sensor. In all cases it is a reliable discrimination against interference pulses and a clear activation of the ignition chain even with light ones Target structures given.
