| 摘 要： | 线性调频信号已经得到广泛的应用,通过谱图-Radon变换可以有效的检测线性调频信号的参数,但是当信噪比过低时,使用谱图-Radon变换就很难有效检测线性调频信号的参数,为此提出了基于谱图-Radon变换-二维小波变换的线性调频信号检测方法,仿真实验表明该方法能在低信噪比情况下检测出线性调频信号所对应的峰值。

| Abstract: | The Spectrum-Radon transform has been an effective approach to detect the widely applied Linear Frequency Modulated(LFM) signals.However,while under the very low SNR environment,it is quite difficult to effectively detect the LFM signals’ parameters.The method based on the 2-D wavelet analysis and Spectrum-Radon transform is proposed in this paper to detect the Linear Frequency Modulated signals under the low SNR environment.Simulation results demonstrate that better detection results can be achieved by this approach compared with the general Spectrum-Radon transform. |
