| Abstract: | An aperture synthetic radiometer (ASR) based on interferometric technology is a new type of passive microwave imaging instrument, which has high spatial resolution. Restricted by devices performance and operating wavelength, however, the system design is difficult at MMW band. In this paper, an 8mm-band aperture synthetic radiometric imaging system based on minimum-redundancy linear array is described, the performance specification of the instrument is analyzed. The preliminary imaging experiment result shows that the system has good passive MMW imaging (PMMWI) performance, indicating a bright outlook for the development of this technique in the future. |
