Pozdniakov Y. Methods of radio sources coordinates determination in multiposition complexes of passive location based on using redundant information

The thesis is devoted to the development of the new methods for radio sources (RS) coordinates determination in the multiposition passive radar complexes. The basic idea is the using of the redundant information about the target location to improve the RS coordinates determination accuracy. In this paper, the distance to object is used as а redundant information. The weight coefficients are used to compensate the high error of the redundant information. It allows to take into account the different accuracy of the passive complex stations. There is also proposed the distance-direction-finding method in terms of redundancy for the coordinate’s determination. According to the results of simulation it was concluded that the root mean square deviation is reduced by using of the researched methods. The practical algorithm was built in agreement with the research results. This algorithm provides 40% increase of accuracy of RS coordinates determination in comparison with the existing approach.
