摘　　要：为了建立具有多重分形特性的海杂波模型,提出了基于分式Brown运动模型的海杂波建模方法。该方法通过将分式Brown运动模型与随机时间序列模型结合,产生了一个近似多重分形的随机过程来模拟海杂波序列。Matlab仿真与实测数据进行对比,结果表明:模型产生序列具有多重分形的性质,可以有效地对海杂波进行模拟。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 characteri comparison with the measured data,the result s this paper is multi-fractal,which can effectively stic and FBM model. Through Matlab simulation and the hows that the sequence produced by the model proposed in simulate the sea clutter.
