摘　　要：复杂的战场电磁环境对于如何有效评估现有电子装备的生存能力及训练电子战装备作战人员提出了严峻考验。介绍了一种战术与技术相融合的思想,采用战术层仿真并结合信号层仿真实现了一种高逼真度的战场电磁环境仿真系统。研究了典型作战场景下目标辐射源的战术与运动行为模型,结合辐射源目标数据库,将辐射源的脉冲描述字通过PCIE高速串行总线实时更新到FPGA板,FPGA采用DDS方案,驱动高速DAC产生不少于20路经过复杂调制的基带雷达信号。该方案已成功应用到某型战场电磁环境仿真系统的设计实现中。The complex battlefield electromagnetic environment has made a serious ordeal for how to effectively evaluate the viability of the existing electronic equipment and training the personnel of EW equipment operator. A simulation thought of combine tactical and technical was proposed, with which a high fidelity of battlefield electromagnetic environment simulation system that tactical layer combined with signal simulation was realized. The typical operational scenarios tactics and behavior model of target radiation source were studied, combined with the database of target radiation source, the PDW of signal source was updated timely to FPGA board by the high speed serial bus PCIE, with the method of DDS, the high speed DAC was driven by FPGA to produce no less than 20 complex modulation baseband radar signals. The method has been successfully applied to the design of a certain type of battle- field electromagnetic environment simulation system.
