摘要
根据对常规防空雷达飞机回波特性及其JEM(Jet Engine Modulation)特征的理论模型和实际信号分析与理解,本文采用小波分析处理方法从回波幅度分量提取JEM特征,用于螺旋桨飞机自动识别。对实测回波数据的分析提取到了比较精确而稳定的JEM特征,并表明该方法具有提取方便、误差较小的优点。
Based on the analysis of the theoretical model and the actual signals of aircraft echoes and the JEM（ Jet Engine Modulation） feature there of , the extraction of JEM feature from echo amplitude component with the aid of wavelet analysis is proposed for automatic identification of propeller-driven aircraft targets. By using this method, precise and steady JEM feature is extracted from actual sample data, which proves the method to be convenient, and with less error.
