PROCEDURE DETERMINING COORDINATES OF OBJECTS IN PROCESS OF PASSIVE BISTATIC RADIOLOCATION Russian patent published in 2003 - IPC

FIELD: radio engineering, radio engineering monitoring means, monopulse radars fixing positions of air targets. SUBSTANCE: procedure determining coordinates of objects in process of passive bistatic radiolocation includes monopulse measurement of angle of arrival of signals of airborne responders of air targets from reception center when range from reception center to interrogator and bearing on it are known, measurement of moments of reception of signals of airborne responders at reception center, extraction of series of signals of airborne responders and computation of difference of elliptical lines of positions of two air targets, difference of angular positions of two air targets from position of interrogator, direction of arrival of signal of airborne responders from reception center, range from reception center to air target. EFFECT: determination of coordinates of air target in process of passive bistatic radiolocation under conditions of lack of signals of interrogator. 2 dwg
