Abstract本文利用卷积理论对综合孔径微波辐射计在顺轨方向的孔径综合进行了理论分析,给出了一定条件下的基线设计,并且分别利用矩量法和基于Backus-Gilbert理论的线性算法两种数值方法进行了顺轨方向地物亮温的反演.数值模拟结果表明,在顺轨方向有效稀疏天线阵设计的基础上,亮温反演达到了很高的精度.
Other AbstractThe theoretical analysis of aperture synthesis in the along-track direction of a synthetic aperture radiometer is presented under the theory of convolution.The baseline design is accomplished according to a spatial frequency domain analysis.The brightness temperature of the earth in the along-track direction is reconstructed by two numerical approaches,i.e.the method of moment and the linear algorithm based on the Backus-Gilbert theory. Numerical simulated test cases show that the reconstruction of the brightness temperature agrees well with the original on the base that the antenna array is effectively thinned in the along-track direction.
