摘　　要：高超声速目标具有高速高机动、绕飞能力强的特点,给雷达的引导带来了极大困难。针对高超声速目标刚进入雷达视距时的场景,设计了相控阵雷达的引导搜索策略,提出了基于引导信息的雷达搜索空域确定和搜索时序设计方法。首先根据目标的运动特性对目标的可能机动空域进行预测,得到搜索空域范围,然后确定目标穿屏时的分布概率密度,进而确定波位编排区域和照射顺序。仿真结果表明,所提引导搜索策略可以快速、高概率地捕获到目标。The hypersonic target has the characteristics of high speed,high maneuverability and strong ability to fly around,which brings great difficulties to the cued search of radar.Aiming at the scene when the hypersonic target just enters the radar line-of-sight,this paper designs a phased array radar cued search strategy,and proposes a radar search airspace determination and search timing design method based on cue information.Firstly,predict the target's possible maneuvering airspace based on the target′s motion characteristics to obtain the search airspace range,and then determine the distribution probability density when the target crosses the screen.Secondly,determine the beam position arrangement area and the irradiation sequence according to the target distribution probability density.Simulation results show that the proposed cued search strategy can capture the target quickly with high probability.
