给出一种基于优化技术的运动补偿方法，通过对运动目标的径向非匀速运动引起的时变的非线性相位误差及非匀速转动引起的转角不均匀进行补偿，从而获得了理想的高分辨目标二维像．本文用这种优化补偿方法对外场实测的飞机回波数据进行了成像实验，成像结果表明，目标二维像聚焦良好，与传统的运动补偿方法相比，成像质量明显得到改善． A motion compensation method based on optimization technique is presented. By compensating for time-varying nonlinear phase errors due to radial non-uniform motion of the moving target and uneven rotation caused by non-uniform rotation, an ideal high-resolution Target two-dimensional image. In this paper, the imaging experiment of aircraft echo data measured in the field was carried out by this optimized compensation method. The imaging results show that the target two-dimensional image is well focused and the imaging quality is obviously improved compared with the traditional motion compensation method.
