N2 - In current main-stream ultra wideban (UWB) devices, hardware imperfections such as antenna mutual coupling, cross-polarization and signal distorations may prevent from achiving high accuracy angle of arrival (AOA) estimation. Due to the difficulties in hardware imperfection modeling, we present a non-parametric support vector regression (SVR) based robust AOA solution in this paper. A set of high relevant features extracted from received signals are adopted as the input for the rat swarm optimizer (RSO) - SVR method. Comprehensive experimental measurements are carried out, which show its performance advantages, particular in cases where traditional phase difference of arrival (PDOA) does not work well.
