摘要
针对复杂的战场电磁环境,提出了一种新的辐射源信号识别方法,即基于分形特征的辐射源目标识别。介绍了分形的相关理论,给出了分形维数中盒维数与信息维数的计算步骤,而后采用距离函数进行判决识别。仿真结果表明提出的基于分形特征的辐射源信号识别算法能得到较高的识别率。
Signal environments become more and more complicated,a novel approach is proposed to recognize emitter signal based on fractal theory.Firstly,fractal theory is introduced.Secondly,box dimension and information dimension of fractal dimension calculation steps are listed.At last,decision-making is performed with distance function.Experimental results of fractal feature recognition of 5 typical emitter signals show that this arithmetic can get high accurate recognition rate,this also verifies the new approach is valid and effective.
