摘要
对特殊体制雷达信号脉内特征的提取是电子对抗的重要研究课题。论文利用韦尔奇功率谱原理来提取信号识别特征参数,并根据提取出的特征参数设计信号识别模型。首先从多种信号中检测识别线性调频信号、相位编码信号、频率编码信,然后分析特征参数的适用范围和信号环境。最后通过仿真分析来验证特征提取算法和识别方法在雷达辐射源信号识别中的可行性。
The feature extraction of new characteristic radar emitter signal is an important problem in ECM. Firstly, several feature parameters for signal recognition is extracted with Welch power spectrum, then a signal recognition model is designed by the characteristic of the feature parameters. Liner frequency modulating signal, phase coded and frequency coded signal are detected and recognized from all kinds of signals. The suitable range and signal＇s condition of the feature parameters are analyzed. Simulation proves the feasibility of the algorithm and the recognition method.
