The Chinese Marine Surveillance Plane B-3837 was devolved to East Sea Branch of State Oceanic Administration and made its virgin flight in May, 2004. So far, China Marine Surveillance Force has her own modern aerial equipments for marine law-execute with the advantage of functioning agilely and operation of larger surveillance coverage, providing powerful safeguard all-round, harmonious and sustainable development of coastal economy. On the plane, three remote sensing scanners have been equipped, including a marine airborne multi-spectrum scanner (MAMS), an optical-electronic platform, and an airborne hyperspectral system AISA+. Among them, MAMS, made by Shanghai Institute of Technology and Physics CAS, will be introduced in detail in this paper. We will describe the specification and characteristics of the multi-spectrum scanner, and then the bands configuration and use of these bands. After that are MAMS' construction and its imaging mode. At last we will focus on its potentiality for oceanic remote sensing.
