摘要
本文介绍了几种将信号循环平稳性用于谱估计测向的新算法,它们将时间和空间处理相结合,从而克服了常规谱估计测向算法存在的不足,并提高了信号的选择性、分辨率、过载能力、检测能力等方面的测向性能,其中的循环最小二乘(CLS),还适用于对相干信号的到达方向(DOA)进行估计。
In this paper,several new algorithms of the cyclostationary of signals used in direction finding are presented.These new algorithms combine temporal processing with spatial processing to overcome weaknesses in conventional methods of the spatial spectrum.used in direction finding.The new algorithms can improve the properties of direction finding in signal selectivity.The cyclic least squares (CLS) are also suitable for the directionofarrival (DOA) estimation of coherent signals.
