| Abstract: | The article shows a method that accurately estimates the frequency sweeping rate of linear chirp signal,utilizes STFT to analyze the linear chirp signal,and receives the time-frequency distribution;then makes use of the transferred result to implement the estimation of frequency sweeping rate.The simulation and computation indicate that the method is with low complexity and in high estimation precision. |
