舰载轻型天线稳定平台电磁兼容设计研究

基于电磁干扰和电磁兼容理论,针对舰载天线稳定平台安装位置处于恶劣电磁干扰环境和它在试验过程中因电源线尖峰信号及其传导发射和电场辐射等引起的电磁兼容问题,提出了采用压敏电阻和瞬变电压吸收二级管(TVS)进行瞬态抑制。采用屏蔽、滤波和接地等技术降低电场辐射以及采用合理的器件进行电磁兼容设计,这些措施在试验及实际应用中取得了很好的效果。

EMC Design for Stabilization Platform of Shipboard Light Antenna

For stabilization platforms of shipboard antennas, EMI problems may occur due to their installation location in an environment of heavy EMI, and due to the spike of power line and its transmission and the radiation of electric field in the process of test. The paper proposes, on the basis of EMI and EMC theories, a transient suppression scheme using voltage-dependent resistor and TVS diode to solve these problems. Shielding, filtering and grounding are used to decrease the electric field radiation, and proper devices are used in the EMC design. These methods have been proved effective in test and practical application.
