Sensor arrangement for the activation of an active body

Abstract

A sensor arrangement for the activation or starting of an active body, especially for a land mine which is deployed against ground and airborne targets. The arrangement includes a waking sensor which is responsive to the approach of a target, and incorporating circuit arrangements for the environmentally-adaptive setting of sensor-evaluating circuits in order to release the operating mechanism employed for combatting the target. Provided is at least one antenna for the radiating of a nondirectional electromagnetic ground or direct wave (which hugs the terrain), and possibly also for the receipt of reflections from the surroundings after the deployment of the active body, as well as after activation by the waking sensor, also for determining the relative movement of a target which has penetrated into the previously encompassed surroundings, due to the reflections thereon.
