Abstract
- The maximum amplitude of matching Fourier transform (MFT) spectrum based on re-sampling of sine (single pulse, SP) signal reflected the frequency of the signal. The analysis of the MFT spectrum of SP signal reflected the MFT theories, from which a method to estimate the frequency of SP signal was proposed; The similarity of the MFT spectrum of the SP and linear FM (LFM) signal was analyzed, then the parameter estimation of LFM signal was presented; The characteristic of promoting the MFT spectrum after adding windows was illustrated, so a method to improve the precision of estimation parameter by adding windows was proposed. The experiments and simulations show the efficiency of the parameters estimation of LFM signal.
