Target positioning method, device and system

Abstract

Embodiments of the invention disclose a target positioning method, device and system. According to the method, space-time registering is carried out on photoelectric measurement information and radarmeasurement information according to site address information and time mark information contained in the photoelectric measurement information and the radar measurement information of a target to be measured respectively; when a tracking target corresponding to the photoelectric measurement information and a tracking target corresponding to the radar measurement information are the same target, and if the distance measurement error of the radar equipment is larger than an angle measurement error, the angle measurement information in the photoelectric measurement information and the angle measurement information in the radar measurement information are fused to generate positioning information of the target to be measured; and if the distance measurement error of the radar equipment is notlarger than the angle measurement error, the angle measurement information in the photoelectric measurement information and the distance measurement information in the radar measurement information are fused to generate positioning information of the target to be measured. According to the method, the defect existing when the target is positioned by utilizing the photoelectric equipment in the related technology is overcome, and rapid and accurate positioning of the target is realized.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of photoelectric early warning, and in particular, to a target positioning method, device and system. Background technique [0002] In the defense of key military targets and civil air defense, the rapid and accurate positioning of incoming targets is helpful for effective interception. It can be seen that it is very necessary to achieve rapid and accurate positioning of targets. [0003] Related technologies generally use photoelectric equipment to detect the spatial position of the target. In order to take advantage of its passive and silent detection, the photoelectric equipment is generally not equipped with a ranging function, so a single unit cannot obtain the spatial position of the target. At present, the method of intersection measurement with two or more devices is used to locate the target. The accuracy of intersection measurement and positioning is affected by various factor...

Problems solved by technology

[0003] Related technologies generally use optoelectronic equipment to detect the spatial position of the target. In order to take advantage of its passive and silent detection, optoelectronic equipment is generally not equipped with a ranging function, so a single unit cannot obtain the spatial position of the target.

At present, the method of intersection measurement with two or more devices is used to locate the target. The accuracy of intersection measurement and positioning is affected by various factors such as target distance, entry baseline angle, etc., and there are intersection blind spots. To cover the entire airspace, multiple deployments are required. Taiwan photoelectric early warning equipment
