分析了传统卫星海洋测高技术在时空分辨率、测距精度和获取二维矢量信息方面的局限性;在此基础上分析研究了宽刈幅测高、多星编队测高、合成孔径测高及Ka频段测高技术体制在克服传统测高局限性的潜在能力;最后提出了未来卫星海洋测高的两种发展方向,即兼顾融合多领域应用的综合型测高技术体制和专题应用型测高技术体制。
The limitations of conventional altimetry are discussed,such as low temporal and spatial resolution,low ranging accuracy and constrained measurements of two-dimensional information,etc.To overcome these traditional limitations,new technology systems are analyzed,such as wide-swath ocean altimetry,altimeter constellation,delay-doppler altimetry and Ka-band altimetry.Finally,two development trends of satellite altimetry are given,namely integrated altimeter technology system which can be used for various applications and altimeter technology system which are dedicated to the particular application.
