防空威胁联网建模与分析

在无人机航路规划中,为了对防空威胁联网进行实时有效评估,从防空指挥控制网络的信息交互结构出发,通过分析防空网信息传输延迟、网络可靠性和节点连接度,建立了防空威胁单元间的联通度模型。基于此,提出了一种适用于威胁联网的目标指示概率模型,并结合雷达组网原理给出了威胁单元的探测信息融合模型。结合网络化火控技术的协同攻击和多次拦截技术,改进了防空威胁网的毁伤概率模型,建立了基于威胁代价的威胁联网模型。通过对比分析威胁联网模型下的无人机航路规划仿真,说明了威胁联网模型评估方法的有效性、合理性。

Modeling and Analysing of Air-defense Threat Netting

The effect of connectivity between air defense units on the kill probability of penetration target is researched from the aspects of communication command and control structure and firepower collaboration. An air defense unit is used as a threat unit to create a threat netting model. A interconnectivity model for the threat units, the reliability of information routing in the network and the connectivity between the threat units. An information fusion model is established for target designation probability and radar detection probability. Based on the joint detection probability of multiple threat units which infers from the principle of radar networking using the networking fire control technology for multiple intercepting and coordinate attack on the penetration target, an final threat netting model is established. Finally,the simulating result in the C++ 6.0 environment proves the validity of the threat netting model.
