摘要
介绍了毫米波辐射计探测空中涂层隐身目标的机理,对涂层隐身目标和光洁金属目标的天线温度对比度进行了对比计算,并利用毫米波辐射计对空中涂层隐身目标和光洁金属目标进行了探测实验。计算和实验表明,隐身目标引起的天线温度对比度比同等大小的光洁金属目标引起的天线温度对比度大;对毫米波辐射计探测空中目标而言,目标的隐身涂层起不到隐身功能。
The mechanism of detecting coating stealth aerial target was introduced.Antenna temperature contrast of stealth target and smooth metal target were calculated,and then experiments of detecting stealth and metal targets by means of millimeter wave radiometer were carried out.Calculation and experiment results show that antenna temperature contrast of stealth target is larger than that of smooth metal target and the stealth coating is ineffective for millimeter wave radiometer detecting.
