A Novel Method of Amplitude Distributed Modeling and Simulation of Compound Clutter under Coastal Environment

Based on firstly studied the coastal compound distributed model of the clutter power in this paper,a novel coastal com- pound distributed model of the clutter amplitude is derived.Secondly the statistic characteristic of amplitude distributed model is lucu- brated on.Then the nonlinear relation of autocorrelation function between the coastal compound clutter random sequences and the corre- lated Gaussian random sequences is derived,which is the important precondition for the clutter simulation based on the ZMNL(Zero Memory Nonlinearity)method.Lastly a new technique of generating random coastal compound clutter sequences is proposed.And the simulation experiment is carried out based on the observed data.The simulation results prove the conclusion proposed in this paper.
