Abstract :
The problems of space-time signal processing in coherent passive radar multistatic system with the adaptive antenna arrays (AAAs) in the receiving points are discussed. It states that the application of a pair of spatially separated adaptive antenna arrays in self-focusing mode, which are involved in two-stage procedure of measurement of multiple jamming sources coordinates by base-correlation method, solves the bearing identification problem and optimizes the parameters of space-time processing system according to the adaptation time. The problem of receiving of two-dimensional responses, which unequivocally characterize space position of each source being located, in the plane of base line - target is solved. The results of the simulations are presented.
