Abstract

This paper presents a practical direction finding receiver based on six-port networks. To expand beam direction angles, improve measurement accuracy, and avoid phase ambiguity, we introduce a dual-baseline architecture into the direction finding receiver. We also propose a calibration technique based on support vector regression (SVR) for the following reasons: The nonlinearity of diode detectors and the asymmetry of six-port junctions can cause measurement phase errors. Moreover, the transmission parameters of two microwave channels differ with changes in received power. Results show that the SVR model can achieve a direction finding accuracy of 0.2932°.
