Linear Chirp Signals Detection by Wavelet-Radon Transform
Guo Qiang Han · Journal of National University of Defense Technology · 2003
WaveletRadon transform is defined that results of wavelet analysis are Radontransformed. 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. Radontransform can detect beeline perfectly and the parameters of linear chirp signals are obtained exactly. The simulation experiment results prove that WaveletRadon transform is a good method of linear chirp signals detection.
