Abstract

The invention discloses a target positioning method and system of full passive detection. The method includes co-station deploying a photoelectric detection system and a radio detection system; fusing, by the matching of an azimuth, the azimuth information and the elevation angle information of a target acquired by the photoelectric detection system of a host station and the azimuth information and the frequency point information of the target acquired by the radio detection system, so as to obtain the azimuth information, the elevation angle information and the frequency point information ofthe target; for the azimuth information, the elevation angle information and the frequency point information detected by different stations, performing target registration by the frequency point information of the target so that according to the location information of different stations, the photoelectric detection systems of different stations performs cross-positioning calculation on the azimuth information and the elevation angle information acquired by the target at the frequency point, and obtains the distance information between the photoelectric detection system of different stations and the target, thereby obtaining the azimuth information and the elevation angle information of the target and achieving target positioning.

Description

technical field [0001] The invention belongs to the technical field of photoelectric detection, in particular to a target positioning method and system for full passive detection. Background technique [0002] The current general-purpose infrared search and tracking and laser ranging detection systems are difficult to deal with the saturation attack of multiple batches of targets, and the current laser ranging range does not match the infrared detection range, which seriously affects the improvement of the overall performance of photoelectric radar. [0003] Multi-station measurement means that multiple platforms perform angular positioning on the target at the same time, and solve the target parameters by solving the geometric relationship. The principle is relatively simple, relying on the high resolution of photoelectric detection, and the ranging accuracy is sufficient. Although the resolution of photoelectric detection is very high, in principle it can obtain high cross...
