Abstract :
The Radon-STFT transform could effectively detect several LFM signals. However, when the energy of these LFM signals diverges greatly, it is quite difficult to detect all LFM signals with the Radon-STFT 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.
