摘要
航天测量船作为天地测量通信的纽带,安装了多种大量的微波测量通信设备,电磁环境较陆地环境相对复杂。船载雷达设备作为测量船的关键组成部分,高低频设备、高低压设备同处在密闭狭小的空间中。电磁兼容性问题的解决需求则更为突出。在船载雷达设备设计之初就必须严格考虑到电磁兼容问题,结合电磁兼容预测设计方法,尽量从源头上降低各分系统设备干扰及受干扰的风险。从产品出厂验证到后续的设备装船改进,需要针对不同的电磁兼容问题,采取不同的解决方案,使系统内各设备协调工作。
Space measurement ship is a link between heaven and earth, which install a wide range of microwave communi- cations equipment, Electromagnetic environment than the land environment is relatively complex. Shipborne radar equip- ment is a key component of the space measurement ship, high and low frequency, high and low voltage equipment in the same confined space. Electromagnetic compatibility issues are more prominent. At the beginning of the product design we must strictly consider the electromagnetic compatibility problem, combined with electromagnetic compatibility predic- tion design method, as far as possible from the source to reduce the interference of subsystems equipment and the risk of interference. From the equipment development to the follow-up equipment shipment, different solutions are taken for dif- ferent electromagnetic compatibility problems, so that all devices within the system work coordinately.
