摘　　要：采用基于MUSIC算法的空间平滑技术代替了应答着陆系统传统的相位干涉式测角算法。重点研究了新算法下应答着陆系统线性非均匀接收天线阵列的设计方法。通过计算机仿真对比分析了设计阵列与同等条件下的均匀阵列的可行性、有效性、分辨力以及精度等性能,有力地验证了设计阵列的可用性和可靠性。The spatial smoothing technique based on MUSIC algorithm was used to replace the traditional phase interferometer angle measurement algorithm of Transponder Landing System （TLS）. The design of nonuniformly spaced linear receiving arrays based on the new algorithm was studied. The feasibility, validity, resolution and precision of the designed array were compared with that of the uniform array under the same condition by computer simulation, which verified the applicability and reliability of the designed array.
