Abstract

A new system based on five-port reflectometers, which measures simultaneously direction of arrival (DoA) in azimuth plane and propagation time of arrival (ToA) of incoherent signals and coherent signals for indoor communication applications is presented in this paper. The receiver operating at 2.4 GHz consists of seven five-ports and a Uniform Linear Array (ULA) of seven quasi-Yagi antennas. The data processing method is also presented. Estimation procedure for joint DoA and ToA is based on the Multiple Signal Classification (MUSIC) algorithm associated with Spatial Smoothing Pre-processing (SSP). The simulation and experimental results show that the signals are well estimated.
