摘　　要：传统多功能雷达仅面向目标特性优化发射资源,在动态电磁环境下面临干扰智能时变、优化模型失配的问题。因此,该文提出一种基于数据驱动的一体化发射资源管理方案,旨在通过对动态干扰信息在线感知与利用提升多功能雷达在动态电磁环境下的多目标跟踪(MTT)性能。该方案首先建立马尔可夫决策过程,数学化描述雷达被敌方截获和干扰的风险。而后将该马尔可夫决策过程感知的干扰信息耦合进MTT精度计算,一体化发射资源管理方法被设计为具有约束动作空间的优化问题。最后提出一种贪婪排序回溯算法对其进行求解。仿真结果表明,所提方法在面向动态干扰环境时不仅可以降低敌方截获概率,还能在被干扰时降低干扰对雷达的影响,改善MTT性能。Traditional multifunctional radar systems optimize transmission resources solely based on target characteristics.However,this approach poses challenges in dynamic electromagnetic environments owing to the intelligent time-varying nature of jamming and the mismatch between traditional optimization models and realworld scenarios.To address these limitations,this paper proposes a data-driven integrated transmission resource management scheme designed to enhance the Multiple Target Tracking(MTT)performance of multifunctional radars in complex and dynamic electromagnetic environments.The proposed scheme achieves this by enabling online perception and utilization of dynamic jamming information.The scheme initially establishes a Markov Decision Process(MDP)to mathematically model the risks associated with radar interception and adversarial jamming.This MDP provides a structured approach to perceive jamming information,which is then integrated into the calculation of MTT.The integrated resource management challenge is formulated as an optimization problem with constraints on the action space.To solve this problem effectively,a greedy sorting backtracking algorithm is introduced.Simulation results demonstrate the efficacy of the proposed method,demonstrating its ability to significantly reduce the probability of radar interception in dynamic jamming environments.Furthermore,the method mitigates the impact of jamming on radar performance during adversarial interference,thereby improving MTT performance.
