摘要
地面雷达机箱开有各种用途的小孔或缝隙,外界的电磁干扰通过孔、缝进入到雷达设备的内部,对内部电路造成干扰。文中从电磁干扰的传播途径出发,对地面雷达机箱在不同情况下的屏蔽效能进行了预测,对屏蔽效能的预测软件进行了探索研究。软件测试表明,使用该预测软件,预测结果与实测基本吻合,对雷达机箱工程设计具有一定的指导意义。
The ground radar box has a few punctures and cracks for the useful. The outside electromagnetic interference always invades into the box through punctures and cracks, while bringing interference on the internal radar equipments, impacting on the internal circuits especially. Thus the paper has just studied on the channel of transmission of the electromagnetic interference, and has forecasted ground radar box＇s shielding effectiveness in any conditions. For the forecasting software of shielded effectiveness, the paper has also carried out lots of explores and studies. Finally, after some tests on software, it has shown that the results of the software, and coincided with the actual measurements in projects. In general, the software has a certain guiding meaning for the design of ground radar box.
