Locating method, system and electronic device for moving target in interference environment

Abstract

The invention discloses a positioning method, system and electronic device for a moving target in a disturbing environment, comprising: inputting the amount of initial sampling data; acquiring current position data of a moving target in a disturbing environment; connecting the most peripheral current position data to form a The polygonal feasibility area of ​​the moving target at the next moment in the interference environment; judge whether the feasibility area is feasible; solve the optimal movement position of the moving target at the next moment in the interference environment in the feasibility area; decompose the polygonal feasibility area into a series of linear area; inscribe the ellipse in the polygon to approximate the feasibility area; maximize the ellipse in the feasibility area composed of a series of linear areas, and obtain the center point of the ellipse, which is the best position of the moving target at the next moment in the interference environment exercise position. It solves the technical problem in the prior art that it is impossible to locate the moving target in the interference environment because the model is difficult to establish or there is no corresponding model at all.

Description

technical field [0001] The invention relates to the technical field of moving target positioning, in particular to a positioning method, system and electronic device for moving targets in an interference environment. Background technique [0002] At this stage, the positioning estimation of moving targets in the disturbance environment includes: closed-loop system, Kalman filter and particle filter. The general closed-loop system needs to establish the motion model of the object, the external interference model, etc. When the interference and other models are not well established, it is difficult for the closed-loop system to better compensate the motion of the system; the model-based Kalman filter assumes the object motion model, However, for sudden disturbances, the position of the object cannot be well estimated; probability-based particle filters generally require markers to update the predicted results, and the markers are relatively fixed.
