The Airborne SAR-ATI-GMTI Based on the Actual Flight State
In this paper the actual airborne dual-channel data is disposed to indicate the moving target by ATI. Consider the SAR-ATI influence caused by the actual flight state, the paper presents the method to compensate the interference phase base on calculate the phase centroid of every sub-image. Besides, this paper simplifies some data processing to realize the real-time GMTI and improves the efficiency. With this method, the actual SAR data is proceeded to get the target’s position and movement parameter. Results prove the validity of the approach.
