基于相关法的合成孔径雷达运动目标的参数估计

本文针对合成孔径雷达运动目标的运动参数估计问题，将方位向频谱相关法用于运动目标的参数估计，本文详细探讨了频谱相关法，给出了相应的框图，在此基础上，利用自适应滤波的概念，引入了时域估计的方法，将两者在计算量进行了比较，并采用在原始数据中注入运动目标的方法，通过计算机模拟，给出了不同信噪比和不同运动速度下的参数估计曲线，将两方法进行了比较，得出了一些有参考意义的结论。

Parameters Estimation of Moving Target of SAR Which Based on the Correlation Algorithm

In this paper, we use Cross-correlation algorithm in solving the problem of parameters estimationof moving target. This paper analyzes the Cross-correlation algorithm. The scheme of this algorithm is given outas well. By adopting the concept of adaptive filter, this paper puts forwards a new algorithm for parameters estimation in time domain. By simulation, we give out the estimation results in the condition of different SNR (SignalNoise Ratio) and different velocities. And the two algorithms are compared. Some useful conclusions are obttainedin the paper.
