%X This paper analyzes the character of moving targets, studies deeply the relationship of Doppler parameters and target shift. A single-channel SAR-GMTI method based on target defocusing shifted difference is proposed. This method employs the character to separate moving targets from stationary. The character is that the azimuth mismatch filter performs compression, it induces shifted difference between the stationary and moving targets because of having different Doppler center. Compare with traditional methods, it is applicable to low and high squint case and the detection ability is significantly improved.
