摘要(Abstract)：
针对140米级及以下尺寸近地小天体(NEO)全天区、全时段监测预警的发展需求，由地基设备完成近地小天体发现和编目的系统已无法满足暗弱目标探测、精细多谱段属性测量、全天区可视覆盖和全时段可用等要求，发展天基监测能力，构建天地协同监测系统成为新趋势。文章在调研已入轨/在研典型近地小天体监测系统及技术基础上，按照谱段、口径、视场等主要指标回顾分析其在小行星监测的效能，并对标分析了近地小天体-宽视场红外望远镜(NEOWISE)、近地小天体巡察器(NEO Surveyor)等两型任务，提出我国近地小天体天基监测系统发展目标，梳理提出可见光/红外多谱段大视场载荷、被动深低温制冷等技术发展方向，可为建设近地小天体防御系统提供发展建议。
