摘要

摘要: 为了提高卫星光通信系统中电荷耦合器件（CCD）空间抗辐射性能，分析了空间辐射环境对CCD器件造成的电离辐射效应和位移辐射效应。通过理论分析和数值模拟计算研究了不同辐射源、不同沟道类型以及不同偏置状态对CCD电荷转移效率（CTE）的影响，结果表明，空间辐射主要在暗电流密度和电荷转移效率两方面影响CCD器件的工作性能。卫星光通信系统中的CCD器件应该选择P沟道CCD，并且在系统不工作时尽量使其处于非偏置状态。

Abstract: To improve the radiation immunity of the charge coupled device (CCD) in satellite optical communication system, the ionization damage and displacement damage effects imposed on CCD in space radiation environment were analyzed. Through theoretical analysis and numerical calculation, the influences of radiation source, buried channel and bias on the charge transfer efficiency (CTE) of CCD were researched. The results show that the space radiation mainly affects the performance of CCD with the bulk dark current density and CTE. The CCD used in satellite optical communication system should be selected as the P channel CCD and set as under unbiased state when the communication system is not working.
