| 摘 要： | 为检验连续波电磁环境下激光雷达的安全可靠性，以单线离轴激光雷达作为试验对象，进行了连续波作用下激光雷达电磁干扰效应试验。通过试验得到，当干扰天线极化方向不同时，同一激光雷达的敏感频率和频段也是不同的，而且干扰信号的敏感频率和敏感频段不同时，激光雷达受干扰的场强的大小不同，在同一敏感频率场强越大，激光雷达受干扰情况越严重；最后分析得到了该激光雷达受到干扰的原因, 为改进激光雷达，提高其电磁环境适应性提供了依据。

| Abstract: | To test the safety and reliability of laser radar in the continuous-wave electromagnetic environment, the electromagnetic interference effect test of laser radar under continuous-wave was operation carried out. The single line off-axis laser radar was taken as the experimental object. Through the experiment, the relationship between the sensitive frequency, sensitive frequency band, and jamming effect of laser radar in different polarization directions and the field strength of jamming signal is obtained. When the polarization direction of jamming antenna is different, the sensitive frequency and frequency band of the same laser radar are also different. And the jamming signal field strength corresponding to the jamming effect of different sensitive frequency and frequency band is also different. The greater the field strength at the same sensitive frequency, the worse the laser radar gets. Finally, the reasons for the jamming of laser radar are analyzed, which provides a basis for improving the adaptability of laser radar to the electromagnetic environment. |
