摘要: | 合成口径雷达(SAR,Synthetic Aperture Radar)为不受天候及昼夜限制 的主动式微波侦测系统。无论在民事上或军事上,利用SAR观念制作高解 析力影像已成为重要的遥测资料来源。由于地表快速变迁且人工日益昂贵 ,利用有效之测量技术协助监测地表之使用具甚高之经济效益。在测量过 程中不与目标物直接接触的遥测技术,随着影像数值化及处理能力的提高 已广泛地展现在实际的应用上。本文主要在探讨ERS-1的MPF(Main ProductionHeader)资料中卫星轨道参数精确度对影像的影响,期能提高 卫星轨道参数的准确度并对影像作几何校正(Geometric Calibration), 产生正射化影像和地图资讯套合(Registration),然后作资料互补或资料 融合,增进对地表之判读。 Synthetic Aperture Radar (SAR) is an active microwave remote sensing systemregardless of the influence of weather and the time of detecting. It is a very important source of remote sensing data using SAR to acquire the high-resolution on imagery for general or military purposes. Due to the fact that the land changes rapidly and the cost is increased, the use of effective measuring techniques to survey the land has become more significant. This paper focuses on the precise determination of the satellite orbit parameters from the MPH (MainProduct Header) documented by ERS-1. The main features developed here is for the geometric calibraction of the remote sensing imagery, which contributes to thesatellite orbit precision. Furthermore, affer the preciser orbit parameters aredecided, the resampling imagery makes registration with the relief map. As acomplementary information, the data of the land can be appropriately justifed. |
