Other significant research includes development of various methods like relative de-correlation
Measure in Polarimetric SAR decomposition, decomposition algorithm development consisting (S-Ω) and Modified (m-χ) and crop monitoring using machine learning. In past, Prof. Bhattacharya was also actively

In this method, one out of the two types of complex special unitary transformation matrices is identified and chosen to transform a unitary rotated coherency matrix in real space based on the greatest value of degree of polarization (DOP) commonly termed as adaptive general four-component scattering

This is a radar polarimetric decomposition technique based on the field of statistical information theory. Here a method is devised to estimate the polarization (OA) orientation angle from the full polarimetric SAR data using the
Hellinger distance.
