Bistatic clutter is part of the ground environment that affects the performance of a bistatic radar system. In continuous wave (CW), moving target indication, and pulse Doppler radars, bistatic clutter residue. The phenomenology of terrain and sea clutter must be characterized, which is the purpose of this chapter. The radar return of transmitter energy scattered by terrain and sea (called surface clutter) from a specific area (called the clutter cell area) is a function of the bistatic angle. The bistatic angle is the angle subtended at the clutter cell by the lines joining it to the transmitter and receiver that are separated in space. The clutter return before signal processing can be orders of magnitude larger than returns from man-made targets such as aircraft or vehicles in the clutter cell.
