Journal ArticleDOI
Dual polarimetric radar vegetation index for crop growth monitoring using sentinel-1 SAR data
Dipankar Mandal,Vineet Kumar,Vineet Kumar,Debanshu Ratha,Subhadip Dey,Avik Bhattacharya,Juan M. Lopez-Sanchez,Heather McNairn,Y. S. Rao +8 more
TL;DR: In this paper, a new vegetation index was derived from dual-pol (DpRVI) SAR data for canola, soybean, and wheat, over a test site in Canada.
Journal ArticleDOI
Target Characterization and Scattering Power Decomposition for Full and Compact Polarimetric SAR Data
TL;DR: In this article, the authors proposed a roll-invariant scattering-type for both full-polarimetric (FP) and compact-PolarIMetric (CP) SAR data, which jointly uses the information of the 2D and 3D Barakat degree of polarization and the elements of the coherency matrix.
Journal ArticleDOI
In-season crop classification using elements of the Kennaugh matrix derived from polarimetric RADARSAT-2 SAR data
Subhadip Dey,Dipankar Mandal,Laura Dingle Robertson,Biplab Banerjee,Vineet Kumar,Heather McNairn,Avik Bhattacharya,Y. S. Rao +7 more
TL;DR: A day-wise and a time-series approach for crop classification using full-polarimetric SAR data is proposed, which has the possibility of generating an intermediate crop map, whenever a SAR acquisition is available for any particular day.
Journal ArticleDOI
Novel clustering schemes for full and compact polarimetric SAR data: An application for rice phenology characterization
Subhadip Dey,Avik Bhattacharya,Debanshu Ratha,Dipankar Mandal,Heather McNairn,Juan M. Lopez-Sanchez,Y. S. Rao +6 more
TL;DR: A unique target scattering-type parameter is utilized, which jointly uses the Barakat degree of polarization and the elements of the polarimetric coherency matrix, and an equivalent parameter proposed for compact-polarimetric (CP) SAR data is proposed for FP SAR data.
Journal ArticleDOI
Dual-polarimetric descriptors from Sentinel-1 GRD SAR data for crop growth assessment
Narayanarao Bhogapurapu,Subhadip Dey,Avik Bhattacharya,Dipankar Mandal,Juan M. Lopez-Sanchez,Heather McNairn,Carlos Lopez-Martinez,Y. S. Rao +7 more
TL;DR: In this paper, the authors proposed three polarimetric descriptors: the pseudo scattering-type parameter (θ c ), the pseud scattering entropy parameter (H c ), and the co-pol purity parameter (m c ) from dual-pol S1 GRD SAR data.
