摘　　要：调研了国际上现有的星载成像高度计系统发展计划和研究现状,对比分析了各星载成像高度计系统配置和参数。同时,与传统高度计相比,阐述了星载成像高度计在观测中尺度、亚中尺度涡上所具备的优势,并从时空分辨率、成像幅宽、轨道选择、测高精度、工作频率和辅助载荷选择等方面系统地分析了国外的技术发展趋势。在借鉴国外星载成像高度计发展经验的基础上,针对海面高度(SSH)测量误差分配、指标体系建立等问题对我国星载成像高度计系统设计给出了建议。The current development plans and research of the space-based imaging altimeter on the mesoscale compared with the traditional altimeter are analyzed.The spatial-temporal resolution,observing width,orbit selection,frequency selection,auxiliary load design and measurement accuracy are systematically analyzed.Based on the experiences of the early space-based imaging altimeter systems the suggestions about the error budget which effects on the SSH accuracy,establishment of system parameter are proposed for the future satellite systems of imaging altimeter design.
