改进的MUSIC算法用于雷达海上目标检测

海杂波的存在严重影响了雷达检测海上目标的性能，海杂波的建模与抑制方法是其研究的重要方面。首先介绍了高频雷达海杂波的产生机理，然后建立海杂波的信号模型。在信号模型的基础上，研究抑制海杂波以及提取目标信号的方法,主要研究对比了SVD和MUSIC方法。利用海杂波信号模型产生满足条件的模拟杂波以及目标信号，仿真出抑制海杂波以及提取目标信号的过程，仿真结果可以验证方法的有效性。

The Improved MUSIC Algorithm For Radar Sea Target Detection

Sea clutter have seriously affected the performance of radar to detect targets at sea, the modeling and suppression method is an important aspect of its research. First introduced the HF radar sea clutter generation mechanism of wave, and then establish the model of sea clutter signal wave. Based on the signal model, study on the inhibition of sea clutter as well as the extraction of target signal method. To comparative study SVD and MUSIC methods. The sea clutter signal model simulation to meet the conditions of the clutter and target signal simulation, suppression of sea clutter and target signal is extracted in the process, the validity of simulation results can verify method.
