火星相机研制

Research on Mars camera

介绍了火星探测的进展及火星相机的科学目标,分析了空间相机及火星相机的特点,展现了课题组经过数年研究在火星相机工程样机的研制过程中取得的成果。研究内容包括:火星表面物质的光谱特性、火星探测光学遥感器的谱段设置、近火弧段星下点光照条件分析、近火点太阳高度角随时间变化规律、火星表面高程的直方图分布特性分析、考虑火星表面高程因素速高比误差造成的像移、火星相机工程样机研制、火星相机工程样机外景成像试验等。总结了过去的工作,为将来进一步研制火星相机打下基础。所研制的火星相机适用于在环火轨道对火星表面的观测成像。

The progress of Mars exploration and the science objective of Mars camera were presented. The characteristics of space camera and Mars camera were analyzed. The research achievements of the research group in the past several years on Mars camera were presented. Research contents include： spectrum characteristics of Mars surface material, spectral band setting of Mars exploration optical remote sensor, nadir illumination analysis at orbit arc near Mars, solar altitude angle changes with time at orbit point near Mars, histogram distribution characteristic analysis of Mars surface elevation data, image motion caused by velocity to height ratio error because of Mars surface elevation, Mars camera engineering model research, imaging experiment with Mars camera engineering model etc. It summarizes the past research and may facilitate further research on the Mars camera. The manufactured Mars camera fits for observation imaging of Mars surface on Mars orbit.
