Abstract介绍了综合孔径微波辐射计的基本思想,以及对地观测的综合孔径微波辐射计与综合孔径射电天文望远镜的区别.给出了综合孔径微波辐射计任意基线干涉测量的可见度函数与基线参数的关系,推导了可见度函数的一般表达式和综合孔径微波辐射计亮度温度反演的一般函数空间表示.给出了亮度温度反演的数值算法和算例.
Other AbstractIn th is paper,the principle of synthetic aperture microw ave radiometer (SARad) is introduced.The differences betw een SARad for earth observation and its parentage in radio astronomy, the synthetic aperture radio telescope,are analyzed,which results in two key technologies of SARad:the design of baseline combination and the image retrieval algorithm.In th is paper,the general relationsh ip betw een the output of an interfe rometer,which is called the visibility function or the spatial frequency samp ling,and the baseline parameters is presented.The general formulation of visibility function and functional exp ression of the brigh tness temperature distribution from retrieved from visibility function are derived.Some discussions on the image retrieval and numerical simulations are given
