| 摘 要： | 现代雷达技术的一个重要发展方向是超宽带、多功能、智能化。提高识别系统的智能化,是雷达目标识别领域的一个关键性问题。雷达所发射的信号向宽带和超宽带扩展。传统的傅里叶变换对非平稳信号几乎无法处理,小波包理论将频带进行多层次划分,并能根据被分析信号的特征自适应地选择相应频带,使之与信号频谱相匹配。

| Abstract: | The super broadband,multi-functions and intelligence are an important development direction of modern radar technology.The key problem of target identification is to improve the intelligentize of the identification system.The transmitted signal of radar extends to broadband and super broadband.Fourier transform is unable to process unstable signal.The broadband is divided into many parts by the wavelet packet analysis.According to the character of the signal,which could choose broadband to match the frequency spectrum. |
