摘要
宽带测向是雷达与电子对抗领域中的一个重要研究课题.在基于信号子空间算法中的双边相关变换(TCT)算法的基础上,对其进行改进,提出了一种新的构造聚焦矩阵的方法.实验证明,新方法在低信噪情况下表现出很强的优越性,相比传统TCT算法,改进后算法具有更高的分辨率和精度.
Wide band direction finding is one of the important researching subjects in radar and electronic counterwork. This paper proposed a new method for constructing focusing matrix based on TCT （two-sided correlation transformation） algorithm. Extensive simulation results demonstrate that this new algorithm has better performance compared to TCT algorithm when the signal to noise ratio is very low.
