Analysis of the Algebraic Tails of GF-3 SAR Images
GF-3 is the synthetic aperture radar (SAR) satellite with the largest number of imaging modes in the world, which operates in 12 imaging modes. Owing to the 1-m resolution imaging mode, GF-3 satellite has beco...

Log-Cumulant Parameter Estimator of Log-Normal Distribution
Based on the second-kind statistics, the log-cumulant estimator is proposed for parameter estimation of the log-normal distribution. The estimates of the shape parameter and scale parameter are independent for...
