For clutters subject to the K and Pareto distribution, the method of ZMNL can't generate random numbers of Gamma distribution whose shape parameters are limited. It leads to biases in the clutter simulation. This paper improves existing methods by random numbers of Beta. The improved method needn't split the shape parameter into the part of integer and non-integer. It can directly generate random numbers of inverse Gamma distribution in any value of shape parameter and simplify the calculation. The simulation results show that compared with traditional method of ZMNL, the PDF simulation curve of the improved method fits better than the theoretical PDF curve and the corresponding MSD is smaller. The simulation performance is improved.
Key words: Pareto distribution; clutter; ZMNL; Gamma distribution
