TARGET TRIANGULATION METHOD Russian patent published in 2011 - IPC G01S5/00 

FIELD: physics.

SUBSTANCE: target triangulation method employs a method of determining three spatial coordinates of a target based on information from two-dimensional direction finders which independently measure the azimuth and position angle of the object. Said method involves determination of the approach point of bearings in space. The determined point lies at minimum distance from two bearings. The bearing of the target is given by the stand point of the bearing source and the direction to the target from the stand point. The stand point is defined by coordinates (x, y, h) and the direction to the target is given by the azimuth and position angle. Parameters are given in the left-side rectangular coordinate system. The method enables to determine additional data of the spatial position of bearings in the vicinity of the approach point.

EFFECT: distinction of real and false targets, shorter time for location using active apparatus, higher potential for passive target detection.
