Abstract :
We propose new techniques for sensor array shape calibration using the subspace fitting and the inversed subspace fitting techniques. In comparison with the maximum likelihood technique of Weiss and Friedlander (1989), the proposed technique requires significantly less computations while similar calibration accuracy can be achieved. Thus, the new proposed techniques are promising in real-time implementation
