摘　　要：针对目标隐身化和电磁环境日益复杂化发展趋势,系统阐述了隐身目标和有源干扰引起的威力衔接问题,指出上述两种场景下系统主波束与补盲波束切换易出现中近区探测不连续,其原因主要由系统补盲设计不合理引起。从理论上推导了上述两种场景下为避免威力衔接问题补盲定时设计方法,结合实例验证了在保证总时间资源不变情况下的系统优化设计方法。得出的结论对优化情报雷达工作模式设计、提升情报雷达战术性能具有指导意义。Considering the development trend of stealth target and more complicate electromagnetic environment,radar detection discontinuity caused by stealth target and active jamming is systematically elaborated in this paper.Detection discontinuity in middle-close range is easy to occur in switching between main beam and blind compensation beam under above mentioned two scenes,and the ultimate cause is unreasonable design of blind compensation beam.Then the timing design method of blind compensation beam for solving the problem of detection discontinuity is theoretically derivated,and the system optimization design method is verified by two examples,which guarantee no increasing in total time resources.The conclusion is of guiding significance for working mode performance improvement and tactical performance improvement of intelligent radar.
