飞艇用测控通信系统的电场辐射超标整改
Rectification on Electric Field Radiation Over Limit of TT&C
Communication System Used in an Airship
摘要 针对某型号飞艇用测控通信系统依据GJB 152A—1997 RE102 测试时,对外辐射发射超标,分析了该飞艇整个系统的电磁发射骚扰特性,并制定了加强线缆与壳体的屏蔽、增大信号线束屏蔽层密度等整改方案。整改后,测控通信系统的电磁发射测试结果符合GJB 151A—1997 的要求。

Abstract The electric field radiation test for the TT&C communication system used in an
airship did not conform to the GJB 151A-1997. The electromagnetic radiation interference
characteristics of the airship were analyzed, and the rectification plan was formulated. The
measures include strengthening the shielding between cables and shells, increasing the
density of the shielding layer of the signal electric cables and so on. After rectification,
the electric field for the TT&C communication system can meet the requirements of RE102
test item.
