| 摘 要： | 针对双谱的特点,提出一种新的雷达信号脉内特征参数提取方法.对接收到的信号首先提取双谱幅度谱并简化为二维特征,然后求取该二维特征的复杂度特征中的盒维数和信息维数.由于不同信号的双谱区别大且对高斯噪声不敏感,因此提取的盒维数和信息维数可分性强、稳定度高,仿真验证了新脉内特征参数的优越性.

| Abstract: | Aiming at the advantage of bispectrum,a novel method for extracting in-pulse characteristics of radar signal is proposed.The bispectrum of received signal is extracted and it is predigested to two dimensions characteristic,then the box dimension and information dimension are extracted from the two dimensions characteristic.For the bispectrum of different signal is distinguishing and it is not sensitive to SNR,the box dimension and information dimension are divisible and steady,the advantage of this new meth... |
