摘要
针对发射机在系统联试中受到电磁干扰(EMI)出现载波失锁等问题,从发射机工作的的外部与内部电磁环境入手,通过对分机产生干扰的各种因素进行统计并进行分析,并采用试验的方法进行排查验证,最终对故障的产生原因进行定位并解决问题,在此基础上得出的解决电磁干扰问题的思路,可以为进行工程设计及系统联试的人员提供借鉴。
Aiming at the phenomena of transmitter＇s unlocking owing to Electromagnetic-Interference, （EMI）, starting with the internal and external operating electromagnetic environment of transmitter, this paper records and analyzes the various factors of interference from subsystem, adopts the method of experiment for elimination and validation, locates the causes of malfunction and corrects it. The solution of electromagnetic interference problem obtained based on this can provide references for the personnel of engineering design and system test.
