摘要
该文研究了高频地波超视距雷达超分辨目标距离、方位角以及多普勒频移估计问题,提出利用波达方向矩阵法实现目标参数的同时估计。该方法利用对波达方向矩阵的特征分解所得到的特征值和相应的特征矢量进行处理,获得目标距离、方位角和多普勒频移的估计。该方法能够实现目标参数估计的自动配对,运算量小,分辨率高。仿真结果验证了该方法的有效性。
Super resolution estimates of target ranges, azimuth angles and Doppler frequencies for HF-Surface Wave Radar （HF-SWR） are investigated in this paper. An algorithm based on the method of Direction Of Arrival （DOA） matrix to achieve simultaneous target parameters estimates is proposed. The estimates of target ranges, azimuth angles and Doppler frequencies can be obtained from the eigenvectors and the corresponding eigenvalues of the DOA matrix respectively. This method is computationally efficient with high resolution, and with automatic combine of the estimated target parameters. Simulation results validate the effectiveness of this method.
