介绍了近些年来国际上几个主要的火星探测遥感相机，包括美国的火星观测相机(Mars Observer Camera,MOC)、高分辨率科学成相试验相机(High Resolution Science Imaging Experiment,HiRISE)，以及欧空局的High Resolution Stereo Camera(HRSC)的发展概况、主要技术指标和技术特点，指出遥感器应具备近红外成像和三维立体成像功能，开展亚米级分辨率精细观测是今后火星遥感探测的主要发展趋势。本文还探讨了不同目标观测对成像分辨率的要求。通过对发展现状的调研和科学需求的分析，为我国今后开展火星可见光遥感观测提供了指标选择和设计的依据。

In this paper, the developing status and primary characteristics of several remote sensing cameras for Mars observation in recent years, including Mars Observer Camera(MOC), High Resolution Science Imaging Experiment(HiRISE), and High Resolution Stereo Camera(HRSC), were summarized. Meanwhile, the imaging resolution requirements for different objectives were also discussed. It is concluded that the tendency of Mars remote sensing is to develop detailed observation with sub-meter resolution. Near infrared imaging and 3D stereo imaging should also be paid attention to. These analyses will provide references for the design of Chinese Mars observation plans in the future.
