摘要：
In this paper, aiming at the imaging and estimation of accelerated moving targets with range and azimuth velocity and acceleration, the influence of high-order phase of echo is analyzed, and the imaging formula of moving target is derived. The fourth-order polynomial Fourier transform is used to improve the former method of fitting the range history directly, whose higher-order coefficient is not accurate. Finally, an example is given to demonstrate the effectiveness of the proposed method.
