覆土层对雷达波衰减及浅埋工事反雷达伪装性能分析

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1.65m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.＃

Soil layer on radar wave attenuation and performance analysis of shallow fortifications anti -radar camouflage

To av oid sa tellite and airborne surv eil la nce radar used to detect the shallow fo rtifications, the soil layer o n the rada r w av e at tenuation and influencing facto rs w as analysed. Wi th the reflectio n-t ransmissio n method, the elect romag netic pa rameters wi th di fferent soil moisture content w ere obtained and the depth of L-Ku radar band penet rating the soil w as calculated. The result o f the larg est penet ratio n depth is 1. 65 meters when the soi l moisture content is 10% and radar band is L-ba nd. The resul ts show that the ov erburden thickness of shallow fo rtifications can be desig ned to sati sfy anti-rada r camouflag e requi rement s. In lig ht of the result s and the anti-radar camouflag e requi rement s, anti-rada r stealth prog ram a nd reference v alue o f overburden thickness of shallow fo rtificatio ns w ere obtained in order to reduce ex po sure symptoms and achiev e counter-radar camouflag e purposes.
