ACTIVE AND PASSIVE ELECTROMAGNETIC DETECTION DEVICE WITH LOW PROBABILITY OF INTERCEPTION

摘要

The present invention relates to an active and passive detection device with a low probability of interception comprising a fixed antenna structure, transmission means and reception means. the antenna structure is formed of a plurality of radiating elements grouped into identical sub-networks and comprises at least one transmitting sub-network and at least three receiving sub-networks; the transmitting means are capable of generating a shape; continuous wavelength of low peak power unfocused in a plane and emitting it, - the receiving means are capable of detecting the targets after formation of a plurality of directional beams from the signals received on the reception subnetworks the reception means are also capable of intercepting radar signals from other radar sources by cross-correlation processing between the signals received on at least three reception sub-networks.
