A device for detection increasing active and passive a low probability interception

摘要

The present invention relates to a device for detecting active and passive with low probability of intercepting comprising an antenna structure which is fixed, and means for sending and receiving means. - the antenna structure is formed of a plurality of radiating elements grouped together in the subarrays are identical and comprises at least one in the transmission network, and at least three in the networks of reception, - the transmission means are adapted to generate a continuous wave of low peak power not focused in a plane and the transmission - reception means are adapted to detect targets after the formation of a plurality of directional beams from the signals received on the receiving array, - the reception means are also able to produce the interception of radar signals coming from other sources radars by a treatment of the cross-correlation between the signals received on at least three in the networks of receiving.
