查询词典 brightness temperature

Because thedetecting of the metal object is important in both military and civil applications, wefocused on the aim and do lots of measurement of the radiometric characteristic ofseveral objects correlating to the metal detecting and got the datum. We also completedthe inversion algorithm of retrieving the brightness temperature from the measureddatum.2 The radiometer is the apparatus of incepting the MMW radialization and is the key partof all passive MMW detecting and imaging system. Our emphasis of radiometerresearch was on a kind of AC radiometer, we discussed its principium, composing andthe recovery of its distorted output signal. Finally we gave out the design of the ACradiometer.3 The focal plane system is the main passive MMW detecting and imaging system atpresent.

由于对金(来源：ABc1C论文8f8f网www.abclunwen.com)属目标的探测在军民应用两方面都很重要，因此文中围绕着对金属目标探测这一中心，对几种相关物体的毫米波辐射特性进行了大量测量实验，获得了相关数据，并进行了亮温反演，给出了计算结果。2毫米波辐射计是接收物体毫米波辐射的高灵敏度接收机，是所有被动毫米波探测成像应用的核心部件，因此文中对毫米波辐射计进行了相关研究，重点研究了用于扫描探测的交流辐射计的原理、构成及其失真信号的补偿问题，并完成了一种交流辐射计的系统设计。3毫米波焦平面系统是当前被动毫米波探测成像的主流系统。
