摘　　要：阵列天线的和、差波束方向图综合问题是雷达研究领域中一个重要的研究方向。针对和、差波束综合过程中的共用单元激励问题提出了稀疏阵的设计,根据波束的性能参数指标设计阵列以达到降低系统复杂度的目的。采用了凸优化算法与压缩感知理论相结合的和、差波束方向图优化合成的新方法。在提高和、差波束方向图辐射性能的同时还通过共用单元激励、减少天线单元总数等形式,有效降低了系统中馈电网络的复杂度,提高了天线的工程可实现性。The synthesis of the sum and difference beam patterns of array antennas is an important research direction in the field of radar research.In view of the excitation problem of the shared unit during the synthesis of the sum and difference beams,the sparse arrays are designed according to the performance specifications of the beams to reduce the system complexity.A new optimized synthesis method of the sum and difference beam patterns is adopted combining the convex optimization algorithm and the compressed sensing theory.The radiation performance of the sum and difference beam patterns is improved,and the number of the antenna elements is reduced with shared unit excitation,effectively reducing the complexity of the feed network in the system,and improving the feasibility of the antenna.
