摘　　要：针对雷达探测高超声速目标预警时间有限的问题,建立雷达网无缝跟踪的时间分配模型并设计一种贪心策略进行求解。该模型基于雷达网无缝跟踪的时间分配原则,考虑雷达跟踪容量、交接要求和时间间隔占用性等约束条件,并采用选择最早发现目标的可见时间窗作为初始跟踪时间窗的贪心策略进行求解,实现了雷达网对该类目标的持续跟踪。设计的求解策略比依次选择时间窗最长的雷达参与跟踪的策略交接次数少10%以上,同时使得目标函数值提升近6%,且算法耗时仅为精确求解算法耗时的7.5‰,提高了反临预警任务规划效能。In order to deal with the problem of limited warning time for radar detection of hypersonic targets,a time allocation model for seamless radar network tracking is established,and a greedy algorithm is developed to address it.Based on the time allocation principle of seamless radar network tracking and taking into account constraints such as radar tracking capacity,handover requirements and time interval occupancy,the model is solved with the greedy strategy of selecting the earliest visible time window of target detection as the initial tracking time window to achieve sustainable tracking of this kind of target throughout the radar network.While increasing the objective function value by almost 6%,the designed method takes more than 10%less handovers than the one that sequentially chooses the radar with the largest time window to participate in tracking.Additionally,the algorithm time is only 7.5‰of the exact solution algorithm time,which increases the effectiveness of early warning detection mission planning for defense against near-space hypersonic targets.
