某型地空导弹发控车车载测试系统抗干扰设计分析

Design and Analyse of Anti-interfere in the Measurement and Control Onboard--system for Air Defense Missile Trigger Device

针对防空导弹发控车车载测试系统恶劣的电磁工作环境,文章综合运用了多种硬件和软件的抗干扰技术,分析了某型导弹发控车车载测试系统实际工作环境电磁干扰来源,并且详细阐述了车载测试系统抗干扰设计中的难点问题,提出了.一种提高车载测试系统现场抗干扰能力的综合实用方案;通过实际应用表明,该综合方案提高了车载测试系统的抗干扰特性.解决了部队应急抢修现场复杂电磁环境对导弹发控车测试造成的影响,保证了测试的正确性和可靠性。

An applied anti--interfere method is presented for the measurement and control onboard--system used for air defense missile trigger device, in which kinds of hard and soft anti--interfere technologies are applied. The method decreases the influence of complex EMI to the measurement and control onboard--system, and ensures the validity and reliability of test.
