摘　　要：为提高质心干扰对抗效果,分辨普通箔条云和包含舰船的箔条云,首次运用分形方法研究箔条云团的分形特性,提出了适用于分形分析的雷达数据预处理方法,并分析了箔条云和包含舰船的箔条云在分形维数上的差别。实验结果显示,分形维数可以准确、稳定的描述箔条云和包含舰船箔条云回波的差异,说明提出的方法可以用于分辨这两类目标,为质心干扰对抗研究和箔条特性研究提供了新思路。To improve the performance of EW countermeasures against centroid jamming,and discriminate between ordinary chaff cloud and ship-chaff combination,for the first time,chaff cloud was analyzed with fractal theory,the corresponding data pre-process method was proposed,and an experiment was carried out to measure the deference between chaff and ship-chaff combination.The experiment results show that fractal dimension is a precise and stable parameter to discriminate between ordinary chaff cloud and ship-chaff combination,indicating that the method proposed is capable of distinguish between the two targets mentioned above,and the work of the essay provides a new way to studying chaff related jamming.
