摘要

A new approach for joint estimating spatial signal frequencies and direction of arrivals based bi-rotation signal subspace is proposed in this paper. The two rotation matrixes are derived to transform signal subspace and to obtain new subspaces to estimate the frequencies and directions of arrivals simultaneously. This approach can be with a simple array structure, M sensors, and computationally efficient with high reso- lution. Computer simulation shows the pre- sented approach has a good performance.
