摘　　要：目的:研究分析军队卫生装备在战场复杂电磁环境下的电磁兼容能力。方法:首先分析信息化战场复杂电磁环境的构成,然后以国家军用标准GJB 151A—1997和GJB 152A—1997中的陆军装备通用要求为参考标准和方法,选择军队医疗机构常规配备的几类急救和诊断卫生装备进行电场辐射发射、电磁辐射敏感度、电源线传导发射和电缆束注入传导敏感度4项电磁兼容试验。结果:大部分受试设备均在30 MHz^1 GHz之间的电场辐射发射和电磁辐射敏感度试验中出现了较为严重的问题,而传导发射和传导敏感度试验结果基本符合国军标要求。结论:国内军队现阶段配备的卫生装备在战场复杂电磁环境下功能正常性均受到不同程度的影响,应重视卫生装备在复杂电磁环境下的分析研究。Objective To study and analyze the electromagnetic compatibility of military medical equipment under the complicated electromagnetic environment in the battlefield. Methods The constitution of the complicated electromagnetic environment in informatized batdefield was analyzed. Then, a series of electromagnetic compatibility experiments on firstaid or diagnostic medical equipment were taken according to the items on army general equipment in GJB 151A--1997 and GJB 152A--1997. The experiments involved radiated emissions, radiated susceptibility, conducted emissions on power leads and conducted susceptibility of bulk cable injection. Results In the frequency range between 30 MHz and 1 GHz, most of the equipment exceeded standards under the radiated emissions tests and could not run regularly under the radiated susceptibility tests. But almost all the equipment met the military requirements in the conducted emissions and conducted susceptibility tests. Conclusion Almost all existing Chinese military medical equipment may not run regularly in the battlefield because of electromagnetic disturbance, and thus the study on electromagnetic compatibility of medical equipment under the complicated electromagnetic environment has to be emphasized.
