针对任意周期雷达任务(侦查、干扰、探测等)在多功能组网雷达中的规划问题,提出了一种可变参数的任务规划方法。首先,分析雷达任务特性,建立可变参数雷达任务模型。然后,设定组网雷达中各雷达任务规划时间窗宽度和开槽宽度,使组网雷达可执行任务的周期与现有任务周期最接近。接着,针对雷达任务任意周期的特点,以任务周期变化量最小为原则对任务周期进行调整,保证多个任务在同一部雷达中不重叠,并且具有周期性。最后,利用启发式算法,以任务驻留时间的平均隶属度最大为目标完成任务规划。仿真结果与实例证明了该方法的有效性。
Aiming at the planning problem of multi-functional networked radar with arbitrary periodic radar tasks (detection, interference, detection, etc.), a task planning method with variable parameters is proposed. First of all, analyze the mission characteristics of radar and set up the variable parameter radar mission model. Then, set the time window width and slot width of each radar mission in the networked radar, and make the period of the task of the networked radar to be the closest to the existing task period. Then, according to the characteristic of arbitrary period of radar mission, the mission cycle is adjusted on the principle of minimizing the variation of mission cycle, ensuring that multiple missions do not overlap in the same radar and have periodicity. Finally, the heuristic algorithm is used to complete the task planning with the goal of maximizing the average membership degree of the dwell time. Simulation results and examples demonstrate the effectiveness of this method.
