Abstract :
In array processing, super-resolution eigenstructure direction-of-arrival (DOA) estimation methods are known to be sensitive to sensor gain, phase and position perturbations. This paper presents a method to calibrate sensor gain, phase and position errors, simultaneously, which is based on three or more disjoint sources in known directions. The method can be applied to arbitrary arrays and low SNR cases. Computer simulations are given to demonstrate the performance of the calibration method
