Abstract

Availability of a good record of paddy rice growth condition is important for obtaining sustainable paddy rice production in agricultural countries like Indonesia. A multitemporal of synthetic aperture radar (SAR) images of dualpolarization Sentinel-1 data collected from January 2020 to January 2021 are good enough to show the variation occurs in two or more regions in Lampung Province based on starting their cultivation time in the paddy field. This study provides the recommendation for detecting paddy rice phenology from two different approaches. Backscatter values (σ0) generated from VV, VH, VV/VH, and VV-VH and dual-polarization radar vegetation index (DpRVI) that has arranged to show the paddy rice growth and phenology pattern are compared with the observation directly from the field at a different time of cultivation period. Both patterns matching with the acquisition time of the direct observation has represented the similar pattern created by radar backscatter and dpRVI with an accuracy of about 85%. The characteristic of phenology and paddy rice growth pattern in the many regions in Lampung province is possible to detect using backscatter values and DpRVI.
