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.
