My work focuses on the advancements and applicability of Synthetic Aperture Radar (SAR) techniques for crop and forest monitoring, ground deformation mapping, and soil moisture estimation. In my work, I have devised a novel methodology to estimate soil moisture over croplands solely using dual-pol GRD SAR data. The advantages of this method include continuous monitoring of soil moisture over a larger scale at higher resolutions. Besides, I have also developed a novel methodology to estimate soil moisture using full and compact polarimetric SAR data. On the other hand, monitoring and quantifying vegetation content directly helps better estimate soil moisture. In this regard, I have developed different vegetation descriptors for dual-pol GRD SAR data. Besides, these descriptors are also capable of estimating crop biophysical parameters. These techniques are successfully implemented using Amazon Web Services (AWS), Google Earth Engine (GEE), and Google Colaboratory (Google Colab). These novel techniques and strategies might be helpful in developing operational agricultural crop monitoring platforms through the Joint Experiment for Crop Assessment and Monitoring (JECAM) international research network as well as upcoming satellite missions. My current focus is developing algorithms for forest canopy height estimation using InSAR and LiDAR data. My career objective is to obtain a researcher position in the field of remote sensing application to agriculture and forestry to associate myself with a progressing science and the nation. Besides, I want to put my expertise to the best use for the remote sensing, agricultural, and forest ecosystems community, as well as widen my technical spectrum.
