针对某高机动两坐标雷达，分析了高功率微波环境、耦合通道、加固总体思路等，对加固要求的确定、前门加固技术、后门加固技术进行了详细论述。用统计学分析的理论确定了雷达的加固要求，提出了高功率微波对雷达前门和后门的几种耦合形式，重点分析了滤波器和限幅器的正确使用、屏蔽、孔洞加固等内容。

In this paper,we analyze the High-power microwave(HPM) environment,coupling paths and general methods for HPM hardening for a high maneuverability 2-D-radar.To determination of how much hardening are needed,the technique for Front-Door hardening and the technique for Back-Door hardening are discussed in detail.Hardening requirements are discussed by statistical methods.We also point out the HPM coupling paths to radar Front-Door and Back-Door,and analyze the hardening by shielding,slots,and correct use methods for filters and limiters.
