摘要: 针对传统多重分形维算法中奇异测度的定义影响了计算速度,定义了一种新的奇异测度,并在研究相关函数和指数的特点之后,定义了基于该奇异测度的多重分形维算法。试验表明,该算法计算速度远远快于传统的盒计数维法,在实际舰船辐射噪声试验中能很好地区分不同的舰船。

Abstract: The singular measurement of the conventional multifractal algorithm being very slow in computation speed,a new singular measurement is defined.A new multifractal algorithm based on the new singular measurement is proposed after studying the features of the related functions and exponents.Experiment results verity the new algorithm is much faster than the conventional ones and can recognize the different ships easily.
