| 英文摘要 | Design limitations for synthetic aperture radiometer are quantitatively analyzed. Firstly, the image quality of a small scaled system with a few baselines is analyzed. The image quality is getting poorer due to the truncation in the spatial frequency domain while the number of baselines is getting fewer. This is called the lower limit for the design. Secondly, the design limitation for a large scaled system, where many baselines exist, is analyzed related with system bandwidth. Once the bandwidth of a system is determined, the physical sampling intervals will behavior differently at the upper and lower frequencies which may generate confusion in the retrieved image. This will limit the increasing of spatial resolution while the number of baselines of a system is increasing. This is called the upper limit for the design. |
