  • This paper analyzes the statistical characteristics of radar clutter, discusses the K-distributed random process used for describing the amplitude characteristics of the clutter, deduces the formulas of relation between K-distributed and Gamma-distributed random variables, and presents a novel method for estimating parameters of K-distributed clutter. Finally, the simulation experimental results of generating the clutter samples and estimating the parameters prove the conclusion proposed.
