| Abstract: | Based on the wireless communication performance of Unmanned Aerial Vehicle（UAV） airborne Synthetic Aperture Radar（SAR）,the design of ground terminal system for UAV airborne SAR is presented in this paper.The key techniques applied in the system are described in detail,and a deep research on Directdraw,double buffering,multithreading and memory mapping techniques is performed as well.Application result proves that the design has realized time reasonable assignment between image process and data receiving.This study will be of great value for designing of ground terminal system for UAV airborne SAR. |
