    Abstract
  • Based on the geometric structure of multi-channel space-surface bistatic aperture radar (SS-BiSAR), the time-frequency and spatial-frequency relationships of clutter and moving target are detailedly analyzed. It is found that the prepositive stationary receiver can improve the spatial separation between moving target and correspondingly competitive clutter, furthermore the processing scheme of space-time adaptive processing (STAP) in SS-BiSAR echo domain is given. Meanwhile, compared to the STAP in monostatic synthetic aperture radar (SAR), it is firstly proved that the minimum detectable velocity in SS-BiSAR system can improve R 0/ R 1(transmitter-to-target distance over receiver-to-target) times. Finally, the computer simulation verifies the effectiveness of the STAP processing scheme.
