摘　　要：为使浅埋工事躲避星载和机载雷达常用侦察波段(L-Ku波段)的探测,分析了工事覆土层对雷达波衰减特性及影响因素,通过反射—透射法测得土壤在不同含水率时的电磁参数,并计算L-Ku波段雷达波对不同含水率的土壤的穿透深度,得出在含水率为10%、雷达波段为L波段时,穿透深度为1.65 m的最大值。结合计算结果及反雷达伪装的要求,得到浅埋工事的反雷达隐身方案及其覆土层厚度的参考值,以降低工事暴露征候,达到反雷达伪装的目的。To avoid satellite and airborne surveillance radar used to detect the shallow fortifications, the soil layer on the radar wave attenuation and influencing factors was analysed. With the reflection-transmission method, the electromagnetic parameters with different soil moisture content were obtained and the depth of L-Ku radar band penetrating the soil was calculated. The result of the largest penetration depth is 1.65 meters when the soil moisture content is 10% and radar band is L-band. The results show that the overburden thickness of shallow fortifications can be designed to satisfy anti-radar camouflage requirements. In light of the results and the anti-radar camouflage requirements, anti-radar stealth program and reference value of overburden thickness of shallow fortifications were obtained in order to reduce exposure symptoms and achieve counter-radar camouflage purposes.
