Review Paper on Crop Area Estimation Using SAR Remote Sensing Data

Abstract

Abstract: Crop detection is a critical and evaluative first step towards almost agricultural monitoring systems. The ability to identify crop type makes it possible to estimate the agricultural area allocated under crop and hence compute relevant statistics providing essential information for crop control of area-based subsidies The capabilities of SAR for discriminating crop type have been previously explored. The main aim is to brief the mechanism of crop acreage estimation and area monitoring using SAR data, Envisat-ASAR, or polarimetric SAR with multi-temporal and multi polarized datasets and review the research progress on crop estimation and area monitoring using microwave remote sensing.Keywords: crop estimation; area monitoring; SAR; remote sensing.
