Abstract
A proximity-fuzed ammunition unit () that can approach a target and where during approach the proximity fuze function effects or gives rise to a voltage pulse pattern that is dependent on objects located along the flight path of the ammunition unit on its approach to the target. The voltage pulse pattern forms the basis for the actution of at least one triggering device () incorporated in the ammunition unit. The electrical circuit or circuits incorporated in or interacting with each triggering device is/are arranged to sense a voltage or amplitude value in the trailing edge of a pulse incorporated in or forming the pattern. If the pattern comprises a number of pulses an indication is given when a predetermined number of pulses has appeared to appears. Each electrical circuit causes or effects the opeation of the triggering device for its actuation depending on the said sensing and/or indication.
