子阵技术是大型相控阵系统成本控制的关键手段,文中介绍了基于凸松弛优化的两类非规则子阵设计方法。 首先,建立了子阵划分模型;然后,介绍了基于迭代凸松弛规划的求解方法和基于加权 L1 范数迭代凸优化的求解方法,这两种方法均能实现子阵精确覆盖,但电性能和计算效率存在一定差异,可根据不同运用需求选择求解方法;最后,仿真实验验证了这两类设计方法的有效性和可行性。

Subarray technology is the key method for cost control of large-scale phased array system. Design methods for two kinds of irregular subarray based on convex relaxation optimization are introduced in this paper. First, a subarray partition model is established and then two solving methods are introduced. Both the iterative convex relaxation programming method and the weighted L1 norm iterative convex optimization method can achieve accurate coverage of subarrays. However, there are some differences in electrical performance and computational efficiency, so the solution method can be selected according to different application requirements. Simulation experiments verify the effectiveness and feasibility of these two design methods.
