摘　　要：文章利用重离子地面模拟源,采用图像分析方法,开展了CCD视频信号处理器件单粒子效应系统性试验与测试研究。首先介绍了器件单粒子效应(SEE)试验方案、试验测试系统组成;然后通过试验研究获得了器件单粒子翻转(SEU)和单粒子锁定(SEL)特征参数,评估了视频信号处理器件单粒子翻转、单粒子锁定效应对系统成像性能的影响。试验结果表明:地面试验测试系统可有效实时判断、统计该器件单粒子效应发生事件,并能直观实时观察到单粒子事件发生时遥感图像的变化;视频信号处理器件随着重离子LET值增大,其单粒子截面呈增加趋势,器件对重离子诱发的单粒子效应比较敏感;单粒子锁定对光学遥感器成像任务的危害程度高于单粒子翻转。最后给出了采取单粒子锁定防护建议。The system test research of single event effects on CCD video signal processor was carried out by heavy-ion source and image analysis method in the paper.The structure of test system and the test schemes were detailedly introduced at first.Then the SEU/SEL characteristic parameters were acquired,and the SEE/SEL effects on the imaging performance of the system were evaluated.The results show that the test system can effectively and timely judge the SEEs,and visually display the corresponding change of the remote sensing image.With the increase of the LET value of heavy iron,the cross section of single event enlarges,and the device becomes more sensitive to SEE induced by heavy-ion.SEL is more harmful to optical remote sensor imaging mission than SEU.Lastly,suggestion is given about adopting systematic enhanced measure for SEL.
