【摘要】：在跟踪加搜索工作方式下,相控阵雷达既要对已捕获的目标保持稳定跟踪,又要继续搜索责任空域发现新目标,为此提出了一种波束调度策略。在交互多模型框架下,基于状态的一步预测估计了目标的预期驻留时间,以检测概率和跟踪精度为约束条件进行了优化,基于驻留时间估计了目标的预期噪声方差和预期误差协方差,定义了目标跟踪的紧迫因子、偏差因子和调度系数,在各个时刻估算所有目标下一时刻的调度系数,根据调度系数大小确定下一时刻的波束指向,指挥波束进行照射,当波束照射到目标上时,更新量测噪声并滤波,当波束未照射到目标上时用预测值表示目标状态,仿真证明了算法的可行性和有效性。
[Abstract]:In the mode of tracking and searching, phased array radar should not only track the captured targets stably, but also continue to search the responsibility airspace to find new targets. In this paper, a beam scheduling strategy is proposed. Under the framework of interactive multi-model, a state-based one-step prediction is used to estimate the expected residence time of the target, and the detection probability and tracking accuracy are optimized. Based on resident time, the expected noise variance and expected error covariance of target are estimated, and the urgency factor, deviation factor and scheduling coefficient of target tracking are defined. The scheduling coefficient of the next moment of all targets is estimated at each time, and the direction of the beam at the next moment is determined according to the magnitude of the scheduling coefficient, and the beam is illuminated by the command beam, when the beam is irradiated to the target. The state of the target is represented by the prediction value when the beam is not irradiated to the target. The simulation results show that the algorithm is feasible and effective.
