We present a method for calibrating the perturbations in the array manifold that resulted from the combined effects of mutual coupling, sensor gain and phase mismatch and sensor positioning error. The array calibration method proposed estimates the sensor positions and calibration matrix from a set of measured steering vectors. The calibration matrix is an array parameter that describes the combined effects of mutual coupling and sensor gain and phase-mismatch. The usefulness and behaviour of the proposed calibration method are illustrated through simulated experiments
