  • Multi-input multi-output spaceborne SAR transmits orthogonal coding signals with multiple antennas from different transmitting phase centers, and receives returns from different receiving phase centers to form multi-channel signals. It can increase the spatial freedom considerably, which gives advantages to detecting ground moving targets. This paper researches the ground moving targets detection technologies for multi-input multi-output spaceborne SAR with space-time adaptive signal processing. Considering the characteristics of the returns of the spaceborne SAR, in the basis of research on the space-frequency adaptive processing algorithm, the text adapts eigen-structure based space-frequency adaptive processing algorithm to suppress the clutter and completes finally the detection of the moving targets. Simulation results proves the validity of proposed algorithm.
