The invention relates to radiolocation, in particular, to bistatic radiolocation detecting “peek-a-boo” and can be used for detecting, coordinate measuring and identifying low-flying targets, including small-sized.The technical result of the proposed invention lies in improving performance characteristics of bistatic radar stations (BRS), namely, increase of coordinate measuring accuracy of air objects, protection of receiving position from a transmitter direct signal influence and passive interference, as well as ability to displaying radar information and transmitting it to points of information collection and processing.The inventive BRS comprises a transmitting position 1 consisting of a transmitter 1.1 and antenna 1.2, directed to a remote from the transmitting position receiving position 2, which includes multibeam receiving antenna 2.1 directed to the transmitting position , N receiving channels (by the number of diagram beams of receiving antenna directivity), each channel comprises in series connected receiver 2.2, a rejection device of the transmitter direct signal and passive interference 2.6 and Doppler's frequency sensing circuit, as well as finder measuring circuit 2.4 in series connected to trajectory forming circuit and identifying air objects 2.5, wherein the inputs of all N receivers are connected to N outputs of the receiving antenna 2.1, and outputs of all Doppler's frequency sensing circuits 2.3 are connected to N inputs of as finder measuring circuit 2.4.Besides, BRS comprises an operator's remote desk 3 consisting of a device of coupling with receiving position 3.1, connected to the output of trajectory forming and identifying air objects block 2.5, device 3.2 of radar information display and apparatus 3.3 of data transmission, the inputs of which are connected to the input of the device of coupling with receiving position 3.1. |
