Measurement of direction-of-arrival of coherent signals using five-port reflectometers and quasi-Yagi antennas

Résumé

The measurement results of detection-of-arrival (DoA) of coherent signals using five-port reflectometers and quasi Yagi antennas are presented. The receiver operating at 2.4GHz consists of eight five-port reflectometers and a uniform linear array (ULA) of eight 2.4GHz quasi-Yagi antennas. The DoA is estimated by measuring the phase difference of signals pitched by the antenna array and by using the MUSIC algorithm associated with Spatial Smoothing Pre-processing (SSP). The phase difference is determined using the five-port technique. The measurement results show that the DoA of coherent signals are well estimated with a maximum error of 2/spl deg/. In addition, we also show that it is capable of estimating the time delay and direction of arrival simultaneously using the five-port technique
