In this paper, a novel blind mutual coupling compensation algorithm especially tailored to L-shaped array(simplified as LCAC) is proposed. This method exploits the incident signals to carry out both 2-Dimensional(2-D) direction of arrival estimation and mutual coupling calibration simultaneously. Based on the banded symmetric Toeplitz structure of coupling matrix between sensors in each sub array...
Calibration of receiving antenna arrays generally yields a square coupling matrix characterizing the array response. It is demonstrated in this paper that in the presence of strong structure scattering, the array response is better described by a non-square coupling matrix. Therefore, the calibration procedure must account for these new matrix dimensions. The different approaches providing accurate...
The theory presented here can be useful for antenna arrays operating in two or three dimensions or located close to near-field scatterers. Contrary to common belief where near-field scatterers generally degrade the array performance, it is now possible to take full advantage of their electromagnetic interactions with the array to improve performance and gain additional information about incident signals...
A self-calibration algorithm (SAL: self-calibration algorithm for L-shaped array) is presented for L-shaped array in the presence of mutual coupling. The proposed algorithm utilizes special mutual coupling characteristic of L-shaped array to decouple the signal source information (DOA) and coupling coefficients of antenna array so that two kinds of parameter estimations can be realized without any...
