New methods for radio sources coordinates determination in the multiposition passive radar system

It is proposed a method of definition of coordinates of radiation sources (RS) using difference-distance measuring method and the problem solution in condition of redundant information about target space location. These approaches are also used in the complex systems “passive radar - altimeter” and “passive radar - active radar”. The mathematical apparatus of the problem solution in terms of redundancy on the basis of a quadratic functional minimization is proposed. The validation of considered method of RS coordinates definition is given. It is carried out statistic simulation of RS coordinates definition, and on a basis of simulation results it is shown increase of the accuracy of RS coordinates in case of application of given method in the systems of passive radio location.
