This cutting-edge resource introduces the basic concepts of passive bistatic radar, such as bistatic geometry, the bistatic radar equation, and analysis of different illuminating signals. Passive radar has been known for almost a century but due to technical limitations has not been developed intensively for decades. Today, the passive radar concept can be realized in practice, which is of great interest to both military and civilian users. This book explains the potential and limitations of passive radar systems as well as the differences between signal processing in active and passive radar. Each of the signal processing stages typically applied in passive radar are described, including digital beamforming, clutter removal, target detection, localization, and tracking.

Correlation processing, which is crucial for passive radar operation, is presented, as well as practical approaches for calculating the cross-ambiguity function. The problems of range and velocity-cell migration are also introduced. The book analyzes and compares different antenna array geometries to show readers the appropriate solution for a particular scenario of passive radar. Cartesian tracking is also included based on the extended Kalman filter. Parallel and sequential updating approaches are introduced and compared. These concepts are illustrated with both simulated and measured data along with examples of passive radar systems, making this book useful for both novice and advanced practitioners.
