| 摘 要： | 干涉式合成孔径微波辐射测量技术是对地无源微波遥感技术的一个重大发展。在微波频段的低端，采用此技术天线无需扫描就能以较小的收集面积获得高空间分辨率的亮温分布图像。较深入地阐述了此技术的系统性能，较详细地介绍了电扫描稀薄阵列辐射计（ＥＳＴＡＲ）的构成原理和基本参数，并概述其原型的某些试验结果。

| Abstract: | Interferometric aperture synthesis radiometry is recently presented as an alternative to real aperture measurements of the earth's brightness temperature from low earth orbit. A substantial reduction can be obtained in this manner in the antenna collecting area required compared to a conventional imaging radiometer. The basic theory and system performance of interferometric synthetic aperture microwave radiometer are deeply explained. The constitution and parameters of the electronically scanned thinned array radiometer (ESTAR), and the experimental initial results for the ESTAR prototype are also described in detail. |
