Global Optimal Algorithm for Joint Estimation of Spatial Signal Frequencies Directions and Array Model Errors

摘要

This paper proposes a global optimal algorithm for estimating spatial signal frequencies, direction of arrivals (DOAs) and array model errors simultaneously. This algorithm guarantees global optimal result instead of partial optimal result got from normal algorithm. From computer simulation results, it is proved that this algorithm can estimate signal frequencies, directions of arrival and array model errors with higher resolution.
