摘要 因受载机平台内电子设备电磁干扰的影响,某机载雷达发射校正时存在通道相位漂移的现象,表现为同一通道相位多次测量偏差超过正常幅度值.在阐述发射校正系统工作原理的基础上,深入分析干扰的来源和机理,提出了综合运用屏蔽、接地、滤波等措施解决电磁兼容问题的具体方法,实现了雷达发射校正系统的可靠工作,为该类工程设计提供了参考. Channel phase-shifting occurs when the transmitting of a certain airbone radar are calibrated, due to the impact of electromagnetic inference out of electronic equipment inside the carrier aircraft platform, which shows the multiple measured deviation for the same channel is above the normal amplitude. On the basis of elaborating the operating principles of transmitting calibration system, this paper analyzes the source and mechanism of interference thoroughly, proposes the concrete method of applying comprehensively shielding,grounding, filtering and other measures for solving the EM compatibility, and achieves the reliable operation of radar transmitting calibration system, which can be a reference for the similar engineering design.
