Sensor system for active armour e.g. for tank - has aerial or oscillator directly coupled to circulator input via directional coupler

摘要

The sensor system has an aerial (1) or an oscillator (4) directly, or via a directional coupler (3), linked to an input of a circulator (2). The latter output is coupled to a mixing stage (5), to which the directional coupler is switchable. The mixing stage output is coupled to a series-connection of an amplifier, filter (6), and an A/D converter (7), and to a Doppler processor (8). The Doppler processor is synchronised with a positioning computer (9). The sensor system is pref. of multiple type, with each part switched to the positioning computer. For each sensor, a min. distance is determiend from the measured values according to a specified equation. USE/ADVANTAGE - Armoured vehicle protection system with precise measuring of incoming projectile trajectory.
