A Novel Keystone Transform Based Algorithm for Moving Target Imaging with Radon Transform and Fractional Fourier Transform Involved
In this paper,we propose a novel algorithm for SAR ground moving target imaging(SAR/GMTI)and motion parameters estimation(MPE)in consideration of Doppler ambiguity.This algorithm involves the keystone transform(KT)and the modified second-order keystone transform(MSKT),Radon transform(RT)and Fractional Fourier transform(FrFT).With this algorithm,the fast moving targets can be focused well and the motion parameters can be estimated accurately even in situation of Doppler ambiguity.The effectiveness of the proposed algorithm is demonstrated by processing the simulated airborne SAR data.
