摘　　要：使用时间延迟补偿实现相控阵波束指向控制,可以提高阵列的瞬时带宽。对延时补偿系统策划设计一般依赖经验和预留设计余量,缺乏相关的理论分析。针对宽带相控阵延时补偿系统进行了详细的理论推导,给出了实时延迟线最小步进和阵面最大延时量的计算方法。分析了多级延时补偿的分配原则,提出了多级延时系统中波位全覆盖的三个充分条件。最后,利用实例分析和仿真,验证了设计方法的正确性和有效性。Using time delay compensation to realize phased array beam pointing control can improve the instantaneous bandwidth of array.The design method of time-delay compensation system usually relies on experience and design margin,and lacks theoretical support.By the detailed theoretical derivation,the calculation methods of the minimum step and maximum delay of true time delay are given.The allocation principle of multistage time-delay compensation system is analyzed.The three sufficient conditions for full coverage of beam position are proposed.Finally,the correctness and effectiveness of the design method are verified by example analysis and simulation.
