摘要
针对强干扰情况,提出一种联合技术估计信源参数。利用干扰正交补子空间消除干扰信号,运用正则相关技术在高斯色噪声和高斯白噪声下估计信号源个数,并估计信号波达方向。仿真验证了这种联合技术的有效性。
In this paper, an incorporating technique is used to estimate the sources parameters in the case of the strong interference. Firstly, the jamming naught space is exploited to mitigate the interference. Then, the canonical correlation technique (CCT) and the technique of direction of arrival (DOA) are respectively applied to estimate the source number and DOA. The simulation results show that the combining technique is valid.
