摘　　要：针对圆柱形布阵的数字阵列天线,分析基于多重信号分类(multiple signal classification,MUSIC)算法的测角跟踪算法和基于线性约束最小方差(linear constrained minimum variance,LCMV)的波束指向算法,提出将2种算法联合使用的方法;并分析通道误差对MUSIC和LCMV算法精度的影响。结果表明,该方法为高速飞行器圆柱共形数字阵列天线工程化研制提供了理论依据。Based on the multiple signal classification(MUSIC),the analysis of cylindrical digital array antennas is carried out.The angle measurement tracking algorithm based on MUSIC algorithm and the beam pointing algorithm based on linear constrained minimum variance(LCMV)are proposed,and the method of combining the two algorithms is proposed.The influence of channel error on the accuracy of MUSIC and LCMV algorithms is analyzed.The results show that the method provides a theoretical basis for the engineering development of cylindrical conformal digital array antenna for high-speed aircraft.
