A precise estimation of the Direction of Arrival (DOA) of a signal is the fundamental functional requirement of antenna technology. A switched receiver system results in substantial reduction in hardware components, measurement complexity and cost of the entire system. In this paper, three diverse calibration methods are investigated on an array antenna with a dual channel switched receiver system. The calibration matrices are generated from the real measurements and implemented on the simulated and the real measurements. Robustness and flexibility of the calibration methods are compared in this paper. A conventional beamformer technique is implemented to perform Direction Finding (DF) of the calibrated system.
