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.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.
