A new algorithm for antenna array position correction

XIONG Li-zhi QI Lan-fen ZHANG Yuan-pei (Dep. of Electronic and Information Engineering,Huazhong University of Science and Technology,Wuhan Hubei 430074,China)  
The error of antenna array element position affects phrase of received array signal. Direction of arrival (DOA) algorithm based on eigenvalue decomposition is very sensitive to phrase error of array signal. Thus,it is necessary to correct the array signal phrase error brought by array element position error. This paper proposes a correct position error algorithm based on subspace optimization. The algorithm can reduces the number of optimize parameters and increases the convergence speed of gradient algorithm. The presented numerical results illustrate its effectiveness.
