Wavelet-Radon transform is defined that results of wavelet analysis are Radon-transformed. Results of wavelet analysis of linear chirp signals are curves on time scale scheme in general. However, Results of wavelet analysis of linear chirp signals are beelines on time frequency scheme. Radon-transform can detect beeline perfectly and the parameters of linear chirp signals are obtained exactly. The simulation experiment results prove that Wavelet-Radon transform is a good method of linear chirp signals detection.
