Abstract

The polarimetric ENTROPY and the ALPHA angle are two important parameters for analyzing polarimetric SYNTHETIC APERTURE RADAR data. They demonstrate the degree of randomness in the polarization of the received signal and scattering mechanism of scatterers respectively. Recently, there has been an increasing interest in compact POLARIMETRY due to its advantages in comparison with full POLARIMETRY. Because the information of compact POLARIMETRY mode is less than full POLARIMETRY mode, it is important to reconstruct full polarimetric information from compact data as better as possible. In this article based on the correlations between ALPHA and ENTROPY parameters in the compact and full POLARIMETRY modes, a novel method is presented in order to reconstruct Cloude-Pottier ENTROPY and a-angle from compact polarimetric data which has reduced computational time and volume in comparison with the previous approach, also the coefficient of determination for ENTROPY and ALPHA has been increased 7.74% and 0.6% and RMS error has been decreased 4% and 0.5% respectively.
