Detection Phase Growth of Paddy Crop Using SAR Sentinel-1 Data

[摘要] Paddy growth monitoring is necessary conducted to ensure successful the harvest and production of paddy. The monitoring can be done by using satellite data, both optical and radar data, which can cover a large area and time observation frequency for seasonal crops, such as paddy. In tropical area, cloudy day usually happen, so that problems can't be handle with optical data. Utilization of radar data that can penetrate the cloud condition can solve the problem, either as a complement of optical data or used alone to monitor the growth phase of paddy. The research was conducted to investigate the capability of Sentinel 1 SAR multi temporal data to detect the growth phase of paddy crop. The research was done in paddy fields belong to Sang Hyang Sri, Subang, West Java during the planting season of 2017. The results found that SAR data in dual polarization (HV, VV), and both combination can be used to detect paddy phase, such as early planting, vegetative, generative, and bare condition after harvesting.
