摘　　要：吸波材料在雷达隐身技术中发挥着巨大作用。为了评估吸波材料的反射率性能,利用现代矢量网络分析仪搭建测试系统,通过测量和比较材料样板与标准金属板的反射波差值,计算出吸波材料反射率。分析仪的强大校准功能使得测量非常精确,同时利用分析仪的时域门功能,能有效滤除背景干扰,从而提高材料样板反射率的测量精度。Absorbing materials play an important role in the radar stealth technology. In order to reflectance properties of absorbing materials evaluation, may set up the test system using the vector network analyzer. The reflected wave differences get refleetivity of the absorbing materials by measuring and comparing a material model and the sdard metal plate. Powerful calibration function of the analyzer makes difference measurement is very accurate. While taking advantage of time-domain gate function,the system can effectively filter out the background reflection interference, thus greatly im prove the measurement precision of material plate reflectivity.
