| 摘 要： | 估计线性调频信号的瞬时频率和调制参数,是进一步获得脉内特征并最终识别信号的基础。线性调频信号模型由软件编程产生,引入瑞利分布高斯谱模型来模拟背景杂波。提出采用小波包分析方法进行消噪处理,以瞬时自相关算法估计信号的瞬时频率,进而求出调制参数。瞬时自相关算法进行了滑动平均改进。计算机仿真实验得到瞬时自相关算法估计瞬时频率的...

| Abstract: | Estimating the instantaneous frequency and modulation parameters of linear frequency modulation(LFM) signal is the base to further fetch the intrapulse characteristics and finally identify the signal.The LFM signal model is generated by software programme,the Rayleigh distribution Gauss spectrum model is introduced to simulate the background clutter.This paper presents to use the wavelet envelop analysis method to perform the noise elimination,uses the instantaneous auto-correlation algorithm to estimate th... |
