Multifractal dimension is the expansion of single fractal dimension,and high-order fractal feature lacunarity is the complement of fractal dimension.The paper studies the multifractal entropy and lacunarity measure variation rate of different modulation radar emitter signal,and the study results indicate that different modulation signal has different multifractal entropy and lacunarity measure variation rate,therefore they can be as the feature parameters in the classification and recognition of radar signal modulation mode.And the simulation results verify that the classification based on multifractal entropy and lacunarity measure variation rate has high recognition rate.
