根据 JEM(喷气发动机调制 )效应和雷达目标回波谱线特点 ,本文提出了一种雷达目标识别方法。此方法是利用小波变换 ,得到雷达目标回波信号的频率调频指数 ,对信号进行相位补偿 ,然后滤掉信号中的机身频谱和多普勒频谱 ,再进行相位补偿 ,用 FFT(快速傅立叶变换 )就可以得到目标的调制谱 ,由此实现目标识别。由实测数据进行分机处理 ,证明利用目标的调制谱识别目标 ,识别效果很好。 According to the characteristics of JEM (jet engine modulation) and radar target echo spectrum, this paper presents a radar target recognition method. This method uses the wavelet transform to obtain the frequency modulation index of the radar target echo signal, performs phase compensation on the signal, and then filters out the fuselage spectrum and the Doppler spectrum in the signal, performs phase compensation, and uses FFT (Fast Fourier Transform ) Can be the target of the modulation spectrum, thereby achieving target recognition. Extensions are processed by the measured data, and it is proved that the target is identified by using the modulation spectrum of the target, and the recognition effect is very good.
