摘要
线性调频信号(LFM)是一类应用广泛的非平稳信号。本文选取高斯线调频小波作为基函数,研究了基于小波-Radon变换的线性调频信号检测与参数估计的基本方法,然后提出了基于小波-Radon变换的多分量LFM信号检测与参数估计的算法。计算机仿真实验结果验证了该算法的有效性。
Linear frequency-modulated（LFM） signal is a kind of broadly applied non-stationary signal. In this paper, Gauss linear frequency modulation wavelet is selected as the base function to study LFM signal detection and parameter estimation based on WT-Radon Transform, then an algorithm for multi-component LFM signal detection and parameter estimation is proposed. Computer simulation results have validated the effectivity of this algorithm.
