摘　　要：为满足中国未来空间交会对接任务对光学成像敏感器工作能力尤其是杂光抑制能力的更高需求,研制新一代空间交会对接光学成像敏感器.该产品多项指标优于其上一代产品神舟八号CCD光学成像敏感器,测量距离由原来的150~2 m范围提升为250~0.9 m范围;目标捕获时间由10 s缩短为0.32 s;抗杂光干扰能力大幅提升,实现准全天候工作.该产品已在中国神舟十一号载人飞船、天舟一号货运飞船与天宫二号的交会对接任务中成功验证,可在后续更好地服务中国空间站、探月三期等工程的交会对接任务.介绍该产品的测量原理、系统组成、地面试验和在轨工作表现等情况,并给出相应结论.In order to achieve the higher requirements and especially the stray light suppression capacity of optical imaging sensor for our future space automated rendezvous and docking task,a new generation camera-type rendezvous and docking sensor（ CRDS） is developed. Compared with the CCD-based vision guidance sensor assembled on Shenzhou-8,the measured range of CRDS is improved from 150 m ~ 2 m to250 m ~ 0. 9 m and the initial acquisition time for target is reduced to 0. 32 s from 10 s. Besides,the stray light suppression capacity significantly improved,which makes it be adaptive in nearly all-weather conditions. CRDS successfully tested and verified in automated rendezvous and docking tasks of SZ-11 TG-2 and TZ-1 TG-2. CRDS can be better applied for the rendezvous and docking mission in future China＇s space station and lunar exploration project. The measurement principle,system composition,ground test and orbit performance of the product are introduced in detail in this paper,and corresponding conclusions are also revealed.
