  7. Abstract:
  8. Forward scatter radar is a special kind of bistatic radar. It is designed to detect targets near the transmitter-receiver line which is called baseline. It has a number of promising features such as larger target radar cross-section (RCS) than that of traditional radars, applicability of shadow inverse SAR (SISAR) algorithms, high performance in automatic target recognition and identification, and robustness to stealth technology. On the other hand, it also has some inherent limitations, including the absence of range resolution (potentially leading to a high Doppler clutter level) and operation within narrow angles relative to the transmitter-receiver baseline. Target detection in forward scatter radars is based on space-time processing.Here a general review of FSR is done focusing on CW FSR which has some benefits against pulsed FSR. Spectral estimation methods are used to improve the performance of STP. Furthermore a new recursive algorithm based on Wiener filter is applied before STP to reduce interferences.Using the results of STP, some iterative methods applied to solve the optimization problem of Maximum likelihood and estimate the coordinate and the velocity of the target.
