| 摘 要： | 本文旨在将混沌、多重分形的理论和方法引入雷达信号处理,分析雷达目标的混沌、分形特性,以有效进行雷达目标识别。文中统计了飞机目标回波信号的Lyapunov指数分布情况,并计算了其多重分形维数,然后在此基础上,利用ART2神经网络进行了飞机目标识别的研究,获得较高识别率。本文的研究表明,混沌、多重分形理论结合人工神经网络在目标特性和目标识别的研究中有着良好的应用前景。

| Abstract: | Based on the recently developed chaos and multifractal theory, this paper introduces new methods for radar signal processing, radar target characteristic analysing and radar target recognition. The Lyapunov exponents are calculated. With the correlational integral method, the multifractal dimensions of radar signal are further obtained.Then by the ART2 neural network,the radar target recognition is carried out.The results of this paper show that the chaos,multifractal and neural network theory have great potentials in the fields of radar signal processing and radar target recognition. |
