摘要

合成孔徑雷達干涉量測技術(SAR Interferometry, INSAR)爲獲取數值高程模型的一種方法。本研究以ERS-1及ERS-2衛星所獲得之複數影像進行雷達干涉量測技術之研究。在資料處理過程中，主要有衛星高度及基線長(baseline)之計算、影像間之套合(Co-registration)、全相位回復(Phase Unwrapping)及產生數值高程之品質精度評估等問題，本研究針對上述各步驟以實作加以探討分析，以瞭解各項處理步驟選項對結果產生之影響。

Radar interferometry is now gaining increasing credibility as a technique for digital elevation models collection. We present here analyses of data collected by the synthetic aperture radar instrument on-board the ERS-1 and ERS-2 satellite on successive orbits. The performance of a radar interferometer system depends on the radar instrument parameters, the orbit parameters, and the errors included by th Co-registration processing and phase unwrapping processing. Details of processing approach are described. Results of different parameters at every processing steps are shown using ERS-1 and ERS-2 inetrferometric SAR data of Chung-Hua, Taiwan.
