STATION OF REPEATER TYPE OF SINGLE SIMULATING INTERFERENCE TO DOPPLER RADARS Russian patent published in 2001 - IPC

FIELD: formation of interference in the form of false moving objects to Doppler radars capable of identification of type of detected traveling object by characteristic spectrum of Doppler frequencies of radar signals reflected from this object. SUBSTANCE: given station includes receiving antenna, single-band balance modulator, transmitting antenna, unit reconstructing spectrum of Doppler frequencies of radar signals reflected from actually traveling objects, unit determining frequency of received signals and change-over switch of sign of Doppler frequency shift. Design of station provides for reception of signals from radars, for their single-band modulation by signals of spectrum of Doppler frequencies stored in reconstruction unit and for emittance of formed signals in direction opposite to direction of reception of signals of radar. EFFECT: capability of simulation of both simple single-point and complex multipoint approaching and moving away objects with high authenticity of simulation in wide band of working frequencies of Doppler radars. 1 dwg
