METHOD OF DETERMINING INCLINED RANGE TO MOVING TARGET USING PASSIVE MONOSTATIC DIRECTION-FINDER

摘要

FIELD: radio engineering, communication.SUBSTANCE: method includes combined processing of two consecutive bearing measurements (azimuth angles to a target ?and ?) and signal power values Pand P, received by a self-contained radial system for the considered measurement times t, t, taking into account that the measurement base point corresponds to the geometric centre of the self-contained radial system, and a line TT- the trajectory of the target - corresponds to points Tand Tof measuring the bearing to the target at time tand t, assuming that the target moves in a straight line, and then calculating the values:, performing two consecutive measurements of the received frequency f, fat measurement time t, tand, based on the measurements, determining the valuesand ??=?-?, and then determining range to the target using the formula:.EFFECT: determining inclined range to a target moving in a straight line without prior data on the speed of the target.5 dwg
