摘要
充分考虑辐射源信号覆盖范围带来的观测约束,提出一种基于动态区间划分的多模型切换轨迹优化算法.该算法根据可探测区域内的观测器构造子区间划分特征向量,在不同的控制层使用相应的切换策略分别设计观测器运动规则、构造性能指标函数.根据设定的目标优化函数,在切换子层综合多种优化算法分别对不同的观测器进行轨迹优化.仿真表明,该方法能够有效解决观测约束下的匀速运动目标轨迹优化问题,具有一定的工程应用价值.
Aiming at the observation constraints of the signal of emitter, a multi-model switching trajectory optimization algorithm based on dynamic range partitioning is proposed. The algorithm constructs a subinterval partition feature vector according to the observers in the detectable region to divide the region. Then the corresponding switching strategy is applied according to different control layer. Meanwhile, this paper designs the movement rules and structures performance index function based on the switching strategy. According to objective optimization function, the optimization trajectory of different observer can be obtained by applying a variety of optimization algorithms in the switching sub-layer. Simulation results show that the method can effectively solve the trajectory optimization problems of the uniform motion target under the observation constraints, with some engineering application value.
