| 摘 要： | 谱图-Radon变换可有效地检测多个线性调频信号,当多个线性调频信号的能量相差较大时,谱图-Radon变换就很难将所有的信号检测出来。为了解决这个问题,文中提出了基于频域CLEAN的检测技术与谱图-Radon变换相结合。使用检测能量相差较大的多个线性调频信号的方法。这种方法可以有效地检测出所有的信号,具有较大的实用价值,仿真实验结果表明这种算法是有效的。

| Abstract: | The Spectrum-Radon transform could effectively detect several LFM signals.However,when the energy of these LFM signals diverge greatly,it is quite difficult to detect all LFM signals with the Spectrum-Radon transform. In this paper,a signal detection method based on CLEAN in Frequency Domain and Spectrum-Radon Transform is proposed.By using this method,all LFM signals can be detected.It means that this method has high practicable value. Simulation results verify the effectiveness of this method. |
