Abstract
An active and passive detection device is provided with a low probability of interception having a fixed antenna structure, transmission means and reception means. The antenna structure is formed by a plurality of radiating elements grouped into identical subnetworks and comprises at least one transmission subnetwork and at least three reception subnetworks. The transmission means are capable of generating an unfocused continuous waveform having low peak power in one plane and of transmitting said waveform. The reception means are capable of detecting the targets following the formation of a plurality of directional beams on the basis of the signals received on the reception subnetworks. The reception means are likewise capable of implementing the interception of radar signals from other radar sources using cross correlation processing between the signals received on at least three reception subnetworks.
