摘要
采用3 mm波段直流辐射计测量涂层隐身材料的物理温度。将辐射计温度与实际辐射面积合成被动截面积来描述目标[1]。介绍了辐射计工作原理,定标及测试方法。最后用极值解反演法编制软件求得目标的被动截面积。
Measured the physical temperature of the coating-stealth material with the 3 mm direct current radiometer. In this paper we compose the radiometer temperature and the actual radiative area to obtain the Passive Cross Section(PCS),with which we describe the objects radiation character. We also introduce the radiometer operation principle, methods of calibration and measurement . At last, we acquire the objects PCS with the extremal solution.
