  • Abstract
    In this paper the author propose a fast and efficient algorithm for multilook K-distribution parameter estimation. It is base on the approximate inverse function of log(ν) - ψ(ν), which is calculated by the least squares nonlinear curve fitting technique. Numerical experiments demonstrate the efficiency and accuracy of this new algorithm.
