| Abstract: | Statistic characteristic of compound K-distributed clutter is studied.A novel coastal compound distributed model of the clutter power with its statistic characteristic is presented and a new model parameter equation is deduced.Secondly a novel coastal compound distributed model of the clutter amplitude is given.The simulation flow of generation of coastal compound clutter sequences is proposed by deducing the method for describing the statistic characteristic of clutter power.Then the simulation experiment results prove the conclusion proposed. |
