摘要
随着红外技术的不断发展,为满足现阶段高品质红外探测器组件对低温工作环境下控温稳定性和电学抗干扰能力等指标的要求。需要对红外探测器组件中易受干扰与对外干扰辐射大的驱动器电路进行电磁兼容相关设计研究。阐述了电磁兼容(EMC)的重要性,同时为了达到最新GJB151B(陆军地面)测试指标要求,介绍了从电路原理设计、元器件选型计算、印制电路板(PCB)布局布线设计、电学滤波设计、整机辐射屏蔽防护等的设计方法与整改措施。使用上述方法的探测器组件顺利取得了GJB151B(陆军地面)中RE102和CE102测试试验的合格数据报告,这为后续的其他类似产品的EMC研究与工程应用提供了理论数据与技术支持。
With the continuous development of infrared technology,in order to maintain the temperature stability,electrical antijamming ability and other properties of the high quality infrared detector components in low-temperature working environment,it is necessary to conduct a research on the driving circuit which is susceptible to interference or having large radiation interference in infrared detector’s components.We state the importance of EMC,and in order to achieve the requirements of latest GJB151 Btest,we design and improve the circuit including schematic circuit design,component selection calculation,PCB board layout design,electrical filter design,whole radiation protective shielding and so on.By applying the circuit,the detector components successfully pass the RE102 and CE102 tests which are the subtests of GJB151 B,which provides theoretical data and technique supports to EMC research on subsequent products.
