Performance Improvement of Direction Finding by Exploiting the Cyclostationary of Signals

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 directionofarrival (DOA) estimation of coherent signals.
