Problems solved by technology

At present, the detection distance and accuracy of passive sensors have far exceeded the capabilities of the human eye. If people's intelligence principles are successfully combined with these sensor technologies, the developed two-station multi-target passive positioning and tracking system will definitely play a huge role. However, there are no relevant research reports on this kind of intelligent bionics in the open literature at home and abroad.

Embodiment Construction

[0064] The present invention is designed on the basis of the existing passive positioning and tracking technology and the coordinated positioning and tracking mechanism of the human eye to the target, including two-station multi-target passive intelligent positioning, intelligent tracking, and intelligent smoothing and tracking of the tracking track. It is estimated that a relatively complete two-station multi-target passive positioning and tracking intelligent bionic new process has been constructed, and the specific implementation is shown in Figure 3:

[0065] (1) Intelligent positioning

[0066] ① Passive detectors at the two stations obtain as much target information as possible for the monitoring area by means of direction finding, frequency measuring, and energy measuring;

[0067] ②Comprehensive map representation of the target information obtained by the two stations respectively, and sharpen the map resolution contrast according to the statistical probability and pri...

Abstract

The invention provides an intelligent simulating method for passively locating and tracking multiple targets in two stations. The method provided by the invention can solve the problem that the traditional method is weak in adaptation of target number and formation, low in locating and tracking precision and too large in calculating amount. The method has the following technical points: (1) a method of differentiating in single station, relating in two stations and cooperating with multiple properties is used for passively locating multiple targets in two stations intelligently; (2) the configurations and cooperated maneuvering strategies of two observation stations are made according to the influence of the system state and deploying manner to the locating precision; (3) the control algorithm is selected based on the filtering model collection and wave self-adaption adjusting algorithm of expert system and machine study; (4) the secondary related algorithm of interrupted track and new starting track and the smoothing algorithm after the relation is succeeded are constructed according to simulation association and inferential mechanisms. The method provided by the invention is suitable for rapidly and accurately locating and tracking multiple moving targets, and has important application values in military and civil aspects.

Description

Technical field [0001] The invention relates to a method for passively locating and tracking multi-moving targets by using two passive sensors. Background technique [0002] Due to the advantages of strong anti-interference ability and good concealment, passive positioning and tracking technology has been paid much attention by scholars and related departments at home and abroad. Among the passive positioning methods, multi-station direction-finding cross-location is widely used, but in the process of passive cross-location for multiple target radiation sources, the intersection of different direction-finding lines will generate a large number of false positioning points , and the number of false positioning points increases sharply with the number of observation stations and targets. What's more serious is that these true and false anchor points will form an extremely complex distribution map in the state of motion. How to quickly and accurately calculate the real positio...
