不同截获时间导致多辐射源的跟踪任务在目标数量等方面呈现时变特征。以提升稳定跟踪目标容量为目的,根据不同类型辐射源的跟踪数据率要求,建立了时-频扫描方案优化数学模型,提出了一种基于负载均衡的优化算法。仿真结果表明,相比于传统扫描方案,基于文中所提方法的扫描方案在灵活性和稳定跟踪目标容量方面性能更优。

Due to different intercepted time, the tracking of multiple emitters is time-varying in many aspects such as target number. To promote tracking capacity, an optimization problem of time-frequency sweeping scheme is formulated with data rate requirements of different emitters. An optimization algorithm based on load balancing is proposed. Simulation results demonstrate that compared with conventional scheme, the time-frequency sweeping scheme designed by the proposed algorithm achieves better performances in both flexibility and tracking capacity.
