Análise dos parâmetros estruturais de tipologias florestais utilizando dados SAR em banda L

Abstract: The main objective of this work is the investigation of the relationship between the polarimetric L-band backscatter (σº) from different incidence angles (collected by the airborne sensor R99-B/SIPAM) and the structural parameters of the primary and secondary forest typologies. The area under study is located at the Tapajós National Forest and surroundings (Pará State, Brazil). Using the Freeman-Durden target decomposition technique, the basic backscatter mechanisms are presented to verify the contributions of… Show more

“…This author associated high H values with intact forest classes, indicating a volume scattering mechanism's dominance. Silva et al [92] modeled and estimated forest biomass from ALOS/PALSAR-1 polarimetric data in from the TNF and found a significant P v attribute contribution in primary and secondary forests. According to the results obtained by Kuplich et al [93], P v component also presented the highest contribution in the discrimination of LULC classes of the TNF and its surroundings.…”
