In this chapter, after introducing the main scheme for a passive bistatic radar signal processor, advanced processing techniques have been illustrated to perform optimized detection with such sensors. In particular, the most essential steps of 2D-CCF evaluation and interference cancellation have been described in detail, showing their optimization in terms of computation resources and effectiveness. Thereafter, many specific problems related to the PBR operation were considered by providing advanced processing schemes for them and showing the results achievable against real data sets.
