扫描式光电成象遥感器正日益成为重要的机载和星载遥感器。本文讨论了遥感器设计的目的,要求及星载、机载遥感器受到的各种限制因素,并分析了它们之间的矛盾和协调途径,得出这类遥感器研制中焦距、比例尺、视场角、相对孔径、地面分辨率、扫描频率及信噪比等主要参数的选择原则。遥感器设计中,如飞行中的定标问题、主要控制装置(V/H计等)及接收器件的拼接等问题也作了阐述。
Scanning photoelectric imaging remote sensing is increasingly becoming an important airborne and spaceborne remote sensor. This article discusses the purpose and requirements of the remote sensor design, as well as various limitations of the spaceborne and airborne remote sensors, analyzes the contradictions and coordination between them, and obtains the focal length, scale, visual Field angle, relative aperture, ground resolution, scanning frequency and signal to noise ratio and other main parameters of the selection principle. Remote sensor design, such as calibration problems in flight, the main control device (V / H meter, etc.) and the receiving device splicing and other issues are also described.
