摘要
从分析雷达嵌入式计算机系统遇到的相互干扰问题入手,运用电磁兼容原理结合电磁干扰辐射、传导模型对系统的影响以及存在问题进行了分析和总结;从系统总体技术方案、硬件和软件匹配设计等方面对电磁兼容性问题提出了一些改进和预测方法.经过靶场多项工程实际应用证明,上述措施提高了雷达嵌入式计算机系统的可靠性、稳定性,取得了较好的效果.
In this paper, the EMI existed in the embedded computer system used in radar is introduced first. Then the EMI problem of the system is analyzed and summarized with the model of EMI radiation and conduction. Finally, some modified methods and prediction methods of EMC about this system are presented. Proved by shooting range applications, the techniques have improved the dependability and stability of the embedded computer system used in radar.
