An alternative approach to interpolated array processing for uniform circular arrays

Cook, Gregory J. ; Lau, Buon Kiong LU and Leung, Yee Hong (2002) IEEE Asia Pacific Conference on Circuits and Systems (APCCAS) 1. p.411-414
Abstract
In this paper, we propose an alternative approach to array interpolation for the sectorized array processing of a uniform circular array. While other approaches do not fully consider the influence of out-of-sector signals on the in-sector response, our approach explicitly addresses this issue. By controlling the out-of-sector response, our interpolated array demonstrates a significantly improved ability to cope with correlated signals which appear both in-sector and out-of-sector. Our approach also allows one to trade between various operating characteristics such as mean transformation error, in-sector error variance and out-of-sector signal suppression. In this way, a degree of versatility in the design method is provided.
