反导预警相控阵雷达网目标分配方法

针对相控阵雷达网跟踪弹道导弹目标时的资源管理问题，分析阐述反导预警作战场景，提出综合目标跟踪精度和雷达切换频率的目标分配效益函数，从雷达能量、时间及雷达与目标可见性三方面建立约束条件，以准确反映目标分配过程中的实际限制，在此基础上构建反导预警相控阵雷达网目标分配模型。根据反导预警任务特点，设置目标分配的自适应间隔，以提高模型设计合理性。就稀疏弹道导弹目标跟踪、密集弹道导弹目标跟踪2种场景进行仿真实验，结果表明:运用所提方法能够有效实现目标分配，提升相控阵雷达网资源利用效率，并能够减少雷达切换次数。 

Target assignment method for phased array radar network in anti-missile early warning

To solve the resource management problem of phased array radar network in tracking ballistic missiles, the scenario of anti-missile early warning combat is analysed, and a target assignment benefit function is proposed, which integrates target tracking accuracy and radar switching rate. Constraints are established from three aspects:radar energy resource, radar time resource and the visibility between radars and targets, so that actual limits in target assignment are reflected. The target assignment model for phased array radar network in anti-missile early warning is constructed on the basis of the objective function and constraints. According to the mission characteristics of anti-missile early warning, the adaptive interval is set for target assignment, which improves model design rationality. Two groups of simulation experiment are conducted separately in the scenarios of sparse target tracking and dense target tracking. The experimental results show that the proposed method can effectively conduct the target assignment, improve the resource utilization efficiency of phased array radar network, and reduce the frequency of radar switching.
