中文摘要：
在已检测出运动目标的基础上，提出了一种基于图像对比度最优准则的运动目标参数估计方法。该方法针对存在方位向速度的运动目标，以图像对比度作为评价标准，对运动目标的速度分量进行二维寻优，当图像对比度函数达到最大值时，得到运动目标的速度分量的精确估计值。经过仿真及实测数据验证，该方法能很好的估计出运动目标的运动参数，并且该方法的测速精度明显优于传统动目标测速方法。
英文摘要：
A moving target parameter estimation algorithm based on contrast optimization criterion was proposed. The algorithm aims at the existence of along-track velocity component. By two-dimensional searching the velocity components, the peak magnitude of the contrast function corresponds to the best estimation of along-track and radial velocity. The moving target parameter estimation method was analyzed in detail and it could enhance the estimation accuracy obviously. Finally, the algorithm was verified by both simulated and measured SAR data.
