电子战中的实时动态场景仿真技术

The Simulation Techniques for Dynamic and Realtime EW Scenarios

产生实时动态的电磁威胁场景是实现逼真的电子战计算机仿真系统的十分重要的一步。在电子战过程中 ,电子战平台的运动、威胁平台的运动、电子战场地形和视线、电磁信号传播方向的变化 ,都时时刻刻地影响着电子战系统所截获到的威胁系统辐射射频的变化。该文探讨影响电磁威胁场景实时动态仿真的电子平台运动、电子战场地形与视线、电磁信号传播方向等主要因素和处理方法 。

It is one important step of building EW half-physical and computer simulation systems to generate the realtime and dynamic EW scenarios. In the electronic warfare, the characteristics of radiate signals intercepted by EW systems depend on the movement of the EW platforms, the movement of the threat platforms, the line of sight and the terrain of the EW field, and the direction of EM signals. The article discusses the main factors and the processing methods of the movement of the electronic platforms, the line of sight and the terrain of the EW field, the direction of EM signals, and so on. The methods have been applied to two actual simulation systems.
