Based on Zero Memory Nonlinearity (ZMNL) transform algorithm, the radar clutter with amplitude dis- tribution characteristic as Rayleigh, Lognormal/and Weibull distributions and power spectrum characteristics as Gaussian spectrum is modeled and simulated and a general procedures for simulating radar clutter based on AMNL are summarized for Radar clutter; and real-time dynamic simulation for coherent radar clutter is implemented which can meet some amplitude distribution and power spectrum characteristics. The simulated results are coincided with the model, and prove validity of ZMNL algorithm.
