Abstract

Both the resolution SAR image and acquisition period are significantly improved with the dramatically development in astronautics and microelectronic techniques, providing new opportunities for SAR specialists to analyze data whose information has never been as abundant as nowadays. In this work, we introduce two algorithms to handle high resolution SAR images: for spatial SAR comparison, we employ a normalized difference algorithm and a Wiener filter; for time domain amplitude analysis, we conduct analysis of variance, or ANOVA. The validation of both algorithms is verified by our campus experiment and successfully applied in the administration work of Hong Kong government.
