Non-cooperative target positioning method

Abstract

The invention provides a non-cooperative target positioning method aiming to solve the problem that the conventional positioning method is sensitive to group path errors of echo signals and instable in performance. The method includes the following steps: forming a synchronous data transfer chain between a receiving station and a transmitting station through a signal synchronization network in time domain, frequency domain and space domain; detecting non-cooperative target scattering information with a receiver by a multi-base positioning system to obtain a group path of a target echo signal, and making a distance information based irrational equation set simultaneous; all the bases transmitting measured target data to a central processing unit through a data transfer chain network, performing trace point correlation, positioning and track processing, and determining a target solving function; if a Tth coordinate information group in a coordinate range satisfies target function conditions, the central processing unit solving position coordinates of a non-cooperative target with the non-cooperative target positioning method so as to finish positioning of the non-cooperative target, and outputting the coordinates of the non-cooperative target.

Description

technical field [0001] The invention relates to the application field of space target detection. In the non-cooperative target detection process, the distance information genetic iterative algorithm is used as the non-cooperative target positioning method to realize the non-cooperative target positioning method. Background technique [0002] Non-cooperative targets generally refer to space targets that cannot provide effective cooperative information, including space debris, temporary failure and obsolete spacecraft, outer space flying objects, hostile aircraft, hostile ships, and hostile soldiers. With the development of modern military, navigation and aviation, the development of non-cooperative target detection technology has attracted more and more attention, and has become a very active research field. In recent years, with the further development of space resources and the intensification of future space combat trends, the outer space of the earth is slowly becoming a ...
