针对现代电子战中对低截获概率(LPI)技术的需求,该文提出了一种基于LPI性能优化的最优功率分配算法。该文首先推导了雷达组网系统的Schleher截获因子。然后,以最小化系统的Schleher截获因子为目标,在满足系统跟踪性能要求的前提下,通过优化组网雷达的功率配置,提升雷达组网系统的LPI性能。并用基于非线性规划的遗传算法(NPGA)对此非凸、非线性约束优化问题进行了求解。仿真结果验证了所提算法的有效性。
In order to meet the demand of low intercept probability (LPI) technology in modern electronic warfare, this paper proposes an optimal power allocation algorithm based on LPI performance optimization. This paper first deduces the Schleher’s intercept factor of the radar network system. Then, with the goal of minimizing the Schleher ’s capture factor of the system, the LPI performance of the radar networking system can be improved by optimizing the power configuration of the networked radar while meeting the system tracking performance requirements. The non-convex and nonlinear constrained optimization problems are solved by the non-linear programming-based genetic algorithm (NPGA). Simulation results verify the effectiveness of the proposed algorithm.
