基于轨道参数修正的PALSAR-2影像正射校正技术
PALSAR-2 image ortho-rectification based on orbit parameters modulation
摘要
Abstract
Evaluation the application potential of the new generation L-band sensor by ortho -rectifying of the PALSAR-2 image has an important significance. The error of orbital parameter in the rectification process will affect the final ortho-rectification precision. To tackle this problem, this paper proposes an ortho-rectification algorithm for PALSAR-2 image based on orbit parameters modulation and simplified calculation. Orbit parameters are modulated by registration of the simulate image and the real image. By using the modulated orbit parameters and simplified calculation of the range doppler(RD) model,ortho-rectification is performed. The method was applied to PALSAR-2 image and PALSAR image at the same time and it was compared with the PALSAR-2 ortho -rectification image without orbit parameters modulation. The result shows that the algorithm has strong operability and high geometric accuracy and that the new generation L-band sensor image's rectification accuracy is higher, which further confirms that the new generation L-band sensor has better performance and greater application po-tential.关键词
