摘要: 嫦娥七号探测器将在月球南极着陆，开展月球南极月表环境的综合探测与研究。其中月表尘埃探头将对极区撞击坑附近自然悬浮的尘埃的粒径、速度以及累积质量通量等特性进行原位测量。本文重点介绍月表尘埃探头的系统构成，阐述系统指标测试和定标方法，分析地面定标试验的结果，测试结果表明尘埃探头满足在月球极区测量自然悬浮尘埃特性的使用要求。
Abstract: Chang'e-7 mission will be conduct by China to comprehensively explore the terrain, landforms, material composition, and space environment of the moon. The Chang'e-7 mission will land at the South Pole of the Moon and conduct exploration of the polar environment and resources. The lunar surface dust detector is an important component of the comprehensive exploration and research of the lunar South Pole lunar surface environment. This article focuses on introducing the system composition of the lunar dust detector, elaborating on the testing and calibration methods of system indicators, and analyzing the results of ground calibration tests. The test results show that it meets the design requirements.-
