| Abstract: | Linearity measurement is very important to weigh the quality of LFM signal. A mathematical model of LFM signal is introduced, and the principle of wavelet-based algorithm, the selection of wavelet function and parameters as well as the characteristics of wavelet-based algorithm are analyzed. A method using wavelet transform to measure the linearity is put forword. |
