One-stationary bistatic forward-looking SAR for moving target detection and imaging with a linear antenna array

One-Stationary bistatic forward-looking SAR (OSBFSAR) is a SAR system that using a geostationary satellite or a near-space low-speed platform as the transmitter and using an airborne or a missile as the receiver. Current literatures and reports about OSBFSAR are mostly about imaging theory and stationary scene imaging methods. In this paper, we propose an OSBFSAR moving target detection and imaging method with a linear antenna array. This method is associated with the two-dimensional spatial variation imaging technology of OSBFSAR and the extended velocity-SAR technology. Using this method, not only the stationary clutter can be suppressed but also the moving targets can be detected and focused well. Some numerical experiments are given to verify the validity of the method shown in this paper.
