AI Technical Summary
Technical Problem
[0024]本发明所要解决的技术问题是，针对现有阵元失效补偿方法在精度、计算效率和鲁棒性之间存在固有矛盾，无法在保持CBF实时处理优势的同时有效恢复因阵元失效导致的波束性能退化的问题，提供一种阵元失效下基于压缩传感的CBF鲁棒性补偿方法及系统，在不牺牲CBF固有鲁棒性和计算效率的前提下，有效恢复阵列完整孔径能力，显著提升阵元失效条件下的波束形成性能
Benefits of technology
[0074] (1) Compared with interpolation: the reconstruction accuracy is greatly improved by using the spatially sparse prior information of the signal instead of relying solely on adjacent array elements, especially in the scenario of continuous multi-array element failure;
