Title:
An Analysis of Wideband Direction-of-Arrival Estimation for Closely-Spaced Sources in the Presence of Array Model Errors 
Abstract:
This letter presents an analysis of wideband direction-of-arrival (DOA) estimation for closely-spaced sources using arbitrary antenna array taking into account the effect of array model error, which is important issue in practical implementation. Based on this analysis, a new wideband DOA estimation method without array calibration is then developed to deal with the effects of array errors. The performance improvement of the proposed method in the presence of array errors is shown in simulation...    »
