Abstract
In smart antenna systems, mutual coupling between elements can significantly degrade the performance of array processing algorithms. Based on the special structure of coupling matrix, this letter presents a subspace-based blind calibration method for uniform circular arrays. The method uses the incident signals to carry out both direction of arrival (DOA) estimation and array calibration simultaneously. In addition, the parameter identifiability condition is also provided. Finally, representative computer simulation results are given to demonstrate the effectiveness and behavior of the proposed methodKeywords
