METHOD OF DETERMINING COORDINATES OF RADAR STATIONS OF COUNTER-BATTERY WARFARE AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2024 - IPC G01S3/46 G01S3/72 G01S5/06 G01S13/46 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of electronic reconnaissance of emitting radio electronic means of radio communication, radio telecontrol, radar and can be used to determine the location of radar stations of counter-battery warfare (CBW) based on the goniometric-difference-ranging method of determining the location of radio-frequency sources (RFS) under the condition of simultaneous reception of the direct radar signal and the radar signal reflected from the projectile. Disclosed method of determining coordinates of a CBW radar station is based on reception of a signal by spaced PRSs connected to each other by signal relay lines. As one reception point, an artillery shell is used, from which the CBW radar station signal is reflected, and the main receiving point is a radio reconnaissance station (RRS), has two receiving antennae and two receiving channels, that is reference and auxiliary ones. Method comprises combined processing by two-channel radio receiving equipment of direct and reflected from projectile CBW radar signals, difference in time of reception of direct and reflected signals is determined by determination of maximum of cross-correlation function of these signals. Determination of the range from the RRS station to the CBW radar station is carried out by the measured delay between the direct and reflected signals of the CBW radar station received by the RRS station, using an analytical method by calculating the sides of the triangle formed by the RRS station location points, projectile-reflector and the position of the CBW radar station, and then calculating the planar coordinates of the CBW radar station taking into account the measured bearing on the radar station. Also disclosed is a device for determining coordinates of a CBW radar station, which implements the method.

EFFECT: simplifying the procedure for determining coordinates, reducing the number of peripheral receiving stations (PRS) of radio monitoring with radio receiving equipment of a goniometric-differential-ranging system for determining the location of radio sources and increasing security of the system.
