基于FBM的海杂波建模方法
Fractal Model for Sea-clutter Based on FBM
摘要
Abstract
The model of radar sea clutter using fractal theory has a wide application in many research fields.This paper proposes inserting a time-varying random sequence in Fractional Brownian Motion (FBM)model for obtaining an approximate multi-fractal stochastic process to simulate the sea-clutter sequence based on the analysis of multi-fractal characteristic and FBM model.Through Matlab simulation and the comparison with the measured data,the result shows that the sequence produced by the model proposed in this paper is multi-fractal,which can effectively simulate the sea clutter.关键词
