METHOD OF DETERMINING POSITION OF WORKING RADIO FREQUENCY TRANSCEIVER BY PASSIVE MULTIBEAM DIRECTION FINDER Russian patent published in 2021 - IPC G01S5/06 G01S3/02 

FIELD: physics.

SUBSTANCE: invention relates to the field of radar ranging and is intended for determination of the operating radar station location having a scanning directional antenna. Method comprises determining location of scanning radar station by means of controlled-beam MBF, receiving and extracting into MBF of direct pulse signals radiated by radar station along narrow beam, pulse signals re-reflected by the underlying surface of the earth or the sea are detected. Method includes receiving direct pulse signals emitted by a radar station when a scanning antenna of the direction radar passes to the MBF, and measuring their duration τ_ν, directing the first beam of the MBF to the radar station, then detecting and measuring durations τ_1i received on the second MBF beam. Detecting and measuring duration of time intervals measured from the leading edge of the signal coming in the second beam to the trailing edge of the signal received on the third beam, after which determining the angle α_i of the radar station relative to the direction of the first MBF beam and the distance from the MBF to the radar station.

EFFECT: technical result of the invention is broader functionalities of the method by providing location of both radar of circular and sector view relative to passive multi-beam direction finder (MBF) in the absence of radio-contrast objects on the ground with simultaneous increase in the range of the system.
