气压高度表的电磁兼容性分析与设计

EMC Analysis and Design for Barometric Altimeter

针对惯性导航系统的重要组成部件之一气压高度表,从电源线传导发射和电场辐射发射两个方面进行了电磁兼容性分析,并提出了相应的电磁兼容改进措施。测试结果表明:经过电磁兼容设计后的气压高度表在电源线传导发射和电场辐射发射两个方面都符合国家标准。

The paper discussed the EMC (Electromagnetic Compatibility) of barometric altimeter, one of the most important units in inertial navigation system, which is about the conducted emission of power lines and the radiated emission of electrical field. Its appropriate measures have been taken. The test results shows that the EMC of barometric altimeter have passed the nation criterion.
