| 摘 要： | 镜像综合孔径可利用较少的天线获得地球遥感所需的高空间分辨率，但是镜像综合孔径辐射测量灵敏度尚未得到深入分析。针对该问题，推导了二维镜像综合孔径辐射测量噪声特性，在此基础上，对一维/二维镜像综合孔径测量灵敏度进行了分析，开展了仿真实验，并与常规综合孔径测量灵敏度进行了分析比较。

| Abstract: | Mirrored aperture synthesis (MAS) has been proposed to utilize a few antennas to provide high spatial resolution for Earth remote sensing. But the sensitivity of MAS is not completely analyzed. For this problem, the characteristic of the noise in 2-D MAS is derived. Further, both the sensitivity of 1-D and 2-D MAS are analyzed. Numerical simulations are carried out to evaluate the sensitivity of a MAS system, and comparisons between the sensitivity of MAS and traditional aperture synthesis are made. |
