The coherent bistatic radar with multi-stage space-time adaptive processing of signals and jamming

The features of spatially-coherent active-passive bistatic radar (BSR) with small baseline for observation of non-radiating targets against the background of strong jamming are considered. The principle of informative completeness (PIG) is formulated on the basis of conclusions of statistical theory of an optimal detection-resolution of signals. Its practical use for the organization of information interaction between active and passive channels of BSR and for getting complete coordinate information about both targets and jammers is shown. The applications of double processor adaptive antenna arrays (AAA) for constructing multi-stage space-time adaptive processing (STAP) of wideband signals of BSR are considered. The results of experimental study of informative channels are given and technological aspects in design of STAP in coherent BSR are discussed
