OPTIMAL INFERENCE OF THE INVERSE GAMMA TEXTURE FOR A COMPOUND-GAUSSIAN CLUTTER

We first derive the stochastic dynamics of a Gaussian-compound model with an inverse Gamma distributed texture from Jakeman's random walk model with step number fluctuations. Following a similar approach existing for the $K-$ distribution, we show how the scattering cross-section may be inferred from the fluctuations of the scattered field intensity. By discussing the sources of discrepancy arising during this process, we derive an analytical …
