本文主要研究内容
作者陶院,高青松,段福伟,丁成斌,金铭(2019)在《星载微波辐射热定标源辐射性能研究与应用》一文中研究指出:基于周期性阵列角锥结构星载微波辐射热定标源,运用时域有限差分算法(Finite Difference Time Domain,FDTD),建立有限大辐射体电磁波散射模型,探索该结构下热定标源在6.3~230 GHz内辐射特性变化趋势,分析热定标源辐射性能(包括反射率r和发射率e)随涂层厚度t、角锥高宽比以及角锥宽度p的变化规律。研究结果表明:热定标源反射率在低频段主要依赖涂层吸波性能,高频段则主要取决于涂层界面反射率;在低频段内,随涂层厚度的增加,热定标源反射率逐渐减小,发射率有所增大,但在高频处,呈现出较快的震荡趋势;在特定涂层厚度下,随着角锥高宽比增加,热定标源在全工作频段内反射率减小,发射率增大,且随着角锥宽度的增加,反射率增大,发射率减小。综合热定标源辐射性能研究结果,结合型号产品具体应用需求,设计开发出热定标源产品,并进行发射率测量,实测发射率均为0.998。
