摘要
根据子空间的基本原理,提出一种新的阵列天线幅相误差校正算法,该方法利用粗略已知的校正源方位角信息进行优化,使用迭代的方法逼近幅相误差的真实值。由于不需要其他的迭代初始值,从而保证该方法能收敛到最优解。计算机仿真实验证明了该方法的有效性。
A new algorithm of array amplitude and phase calibration is introduced in this paper,based on the principle of subspace.It uses iteration to get the best solution of array errors in the presence of the known course DOA information.Since other initial values are not needed,this new method can get the optimal solution.The feasibility of this method is proved through computer simulation.
