中文说明：
基于凸优化算法，频率分集阵列天线在全时空域内可控点聚焦，实现对动目标追踪、多目标聚焦，可用于实现点对点秘密通信。
English Description：
Based on the convex optimization algorithm, the frequency diversity array antenna can control the point focusing in the whole space-time domain to achieve moving target tracking and multi-target focusing, which can be used to realize point-to-point secret communication.
