Moving satellite interference source positioning method based on searching optimization filtering

The invention discloses a moving satellite interference source positioning method based on searching optimization filtering, and belongs to the field of interference source positioning in satellite communications. The method aims to solve the problem that double satellites are used in a ground positioning system for forwarding signals so as to position a moving satellite interference source. According to the method, observation information is fully utilized, searching optimization is conducted on location reference points in a time difference line, a pre-estimated value of the location of the moving interference source is obtained, then a filtering algorithm is used for processing the pre-estimated value, and accordingly the moving satellite interference source can be positioned. The moving satellite interference source positioning method based on searching optimization filtering is developed based on an existing motionless satellite interference source positioning technology and provides a feasible idea and method for positioning the moving satellite interference source.
