Abstract:

The 2-dimension uniform acceleration moving target multi-static inverse synthetic aperture radar (ISAR) imaging model is introduced, and an imaging and motion parameter estimation algorithm is proposed in order to overcome the disadvantages of monostatic ISAR imaging. Furthermore, multi-static ISAR target imaging constraints are analyzed. The positions of target scatters are obtained by solving the range direction projection equations. Based on the azimuth Doppler equations, motion parameters are estimated accurately after the inherent rotation velocity of targets and the rotation velocity of turntable light of sight are separated effectively. The multi-static ISAR 2-dimension imaging model and motion parameters estimation method are verified by simulation experiments.
