Abstract :
This paper is concerned with the array shape self-calibration problem when the array gain pattern of each sensor is spatially dependent and unknown. We adapt a constant modulus approach (CMA) to improve the precision in the sensor localization. We will see how this original method conducts to build particular antenna configurations appropriate for self-calibration. The performance improvement lies in a strong bias reduction.
