Identification of Snow Using Fully Polarimetric SAR Data Based On Entropy and Anisotropy

Abstract: Recently, with the extensive availability of fully polarimetric synthetic aperture radar (SAR) data, methods that are simple and efficient, and involve lesser computation and data processing, are needed to be explored for snow cover mapping. This paper analyzes different polarimetric parameters such as entropy, anisotropy, and the mean scattering angle for the identification of snow cover area. We present a novel index for mapping snow cover based on the assessment of entropy (H) and anisotropy (A) using fully… Show more

“…Enhancing the The Cloude-Pottier Entropy-based decomposition is widely employed in various applications. The H/A/a approach has found utility in land cover classification [60,61] across diverse terrain types, including forested areas [62], snow-covered terrains [63,64], wetlands [65][66][67], and agricultural regions [68,69]. Although Cloude-Pottier is a noncoherent method, it has also been evaluated for target detection procedures despite not being endorsed for such applications [70,71].…”

“…Remote sensing techniques have been frequently used to monitor the climate conditions such as precipitation and temperature (Rees, 2005; Varade & Dikshit, 2019; Varade et al., 2020). The radio detection and ranging has been used in weather monitoring and forecasting (e.g., Bevis et al., 1992; Massonnet & Feigl, 1998).…”
