摘　　要：安装于载体上的雷达容易受所处环境的电磁影响不能正常工作。如何在满足雷达性能指标前提下,对雷达进行电磁兼容设计,保证雷达不受电磁环境的影响。本文在某雷达性能设计过程中,采取多级接地、屏蔽及滤波等设计措施,消除或抑制产品内部可能产生的电磁干扰,实现雷达的电磁兼容设计。实验验证结果表明,产品电磁兼容性满足EMC鉴定实验要求。Radar mounted on the carrier is easily affected by the electromagnetic environment,resulting in improper work.The design of the radar electromagnetic compatibility should not only meet the key function of the radar but also prevent the radar from the influence of the electromagnetic environment.Therefore,during the process of designing the radar with electromagnetic compatibility,some techniques are used,such as such as multi-level grounding,shielding and filtering.The experimental results verify that the electromagnetic interference generated internally was eliminated or suppressed and the electromagnetic compatibility of the product has been greatly improved.
