An investigation was carried out to generate banana area map in major banana growing districts of Tamil Nadu using polarized (VV and VH) Synthetic Aperture Radar Satellite images Sentinel 1A SAR Data with VV and VH polarization at 12days interval were downloaded for the crop growing season. Crop parameter for classification was retrieved by continuous monitoring across the study area Ground truth collection and accuracy assessment was carried out using the validation points. Using temporal data collected for the cropping period, spectral dB curve was generated for VV and VH polarization. The dB values do not show much variation both under VV and VH polarization. The total banana cultivated area as estimated for Tiruchirappali, Karur and Erode districts were 5457 hectares, 3865 hectares, and 9432 hectares respectively
Key words : VV and VH Polarization, Sentinel-1A, SAR, Banana, Accuracy.
