Abstract

A target-protecting device for rendering harmless a projectile impacting on the device includes a reactive armor extending over the target and being composed of a plurality of individually electrically ignitable modules. Each module has an explosively acceleratable armor plate. An additional armor extends over and is positioned at a distance from, the reactive armor. A sensor arrangement is provided at the additional armor for emitting a signal identifying a location of projectile impact on the additional armor. An electronic monitoring device receives signals from the sensor arrangement for determining, from the signals, a position of the projectile upon penetration of the additional armor and for applying an ignition signal to a respective module to explosively accelerate the armor plate of such module toward the projectile.
