A New Method for SAR Speckle Noise Reduction (CST Filter)

Abstract: RESUMELes donnees obtenues apartir d'un radar aantenne svnthetioue (RAS) presentent, en principe, du chatoiement. Le chatoiement est perticulierement important dans les donnees treitees avec un petit nombre de visees. Dans Ie present article, les auteurs proposent une nouvelle methode destinee areduire Ie chatoiement. II s'egit d'une methode de filtrage iondee sur une loi de chi cerre. En posant comme principe que l'on peut estimer la distribution du bruit observe al'eide d'une distribution theorique. cette me… Show more

“…Meanwhile, there are the following papers which deal with noise analysis, A method of speckle noise reduction for SAR data is proposed [16] together with a new method for SAR speckle noise reduction (Chi Square Filter: CSF) [17]. On the other hand, sensitivity analysis of Fourier Transformation Spectrometer: (FTS) against observation noise on retrievals of carbon dioxide and methane is conducted [18].…”
