In this paper, we propose two approaches to provide direction of arrival using homodyne detection systems technologies like six-port and five port reflectometers. The choice of the reflectometers' type becomes critical in parallel of the circuit capability, i.e. in terms of the number of signals to be detected simultaneously. We present our study by implementing MUSIC algorithm at the output of two different homodyne receivers. The results are deduced from the simulation of the characteristics of each system, using the Advanced Design System (ADS) and MATLAB.
