Design of a Test System for Complex Electromagnetic Environment Simulation and Reconnaissance Test

为满足机载装配的侦察系统生产与维修的测试需求,本文设计了一种复杂电磁环境模拟及侦察测试系统,主要由显控与场景控制计算机、基带信号模拟单元、射频变频单元、射频调理单元和软件部分等组成.测试系统充分运用了综合控制、综合仿真、综合数字中频、综合射频的"四综合"理念,采用了开放式架构,进行了人机工效优化设计,实现了逼真的战场复杂电磁信号环境的模拟仿真,并加入剧情设计测试方法,对机载侦察系统的各项性能指标、极限指标进行测试,检验出机载设备的实战战术性能,为装备的定型及部队的作战使用提供真实可信的技术依据.

In order to meet the testing requirements for the production and maintenance of airborne reconnaissance system,a complex electromagnetic environment simulation and reconnaissance testing system is designed,which is mainly composed of the display control and scene control computer,the baseband signal simulation unit,the RF frequency conversion unit,the radio frequency conditioning unit and the software part,etc.The system fully uses the"four comprehensive"concept of comprehensive control,comprehensive simulation,comprehensive digital intermediate frequency and comprehensive radio frequency.The open architecture is adopted and the ergonomics optimization design is carried out.The realistic simulation of the complex electromagnetic signal environment of the battlefield is realized,and the plot design and test method is added to the various airborne reconnaissance systems.The performance index and limit index are tested to verify the actual tactical performance of the airborne equipment.The airborne reconnaissance system provide a true and credible technical basis for the equipment setting and the operational use of the troops.
