基于MCM法的大型有源相控阵二维阵列校准

MCM法可以在没有微波暗室或外场条件不理想的情况下对大型阵列进行校准。文中将此方法应用于大型有源相控阵二维阵列校准,得到了基于MCM法的二维阵列口径分布推导公式,对该方法应用于二维阵列时的新特点新问题进行了分析,比较了不同推导方式下的阵列性能差异,并进一步对该方法的误差统计特性参数进行了研究,最后提出了MCM法在工程应用中需要注意的问题和应对措施。

MCM-Based Calibration of Large 2-Dimensional Active Phased Array

Mutual Coupling Method(MCM) can be used for large array calibration when there is no anechoic chamber or ideal far field.MCM is applied to large 2-Dimensional active array calibration and formulas of array distribution are presented in this paper.The problems in large 2-Dimensional array calibration based on MCM are analyzed,this paper compares the characteristic differences of the deduced ways and further gives the error statistics,finally puts forward some points that should be payed attention to in engineering applications and the measures for those points.
