Abstract：The iterated estimation of DOA and polarization for completely polarized electromagnetic waves is proposed based on an partly calibrated polarization sensitive array with different type of polarization sensitive antennas, mounted on airframe. The proposed algorithm can estimate the array’s error based on the partly calibrated polarization. Then, the polarization steering vector of single polarization sensitive antenna is estimated by this array’s error, so that the sources’ DOA and polarization are estimated based on the polarization steering vector. The estimating accuracy is enhanced by means of iteration. The simulations show that the proposed algorithm has convergence and robust character.
