| Abstract: | This paper introduces the ability of match Fourier transform resolving chirp signals. The study of Fourier frequency affecting resolution is performed. In this paper, the simulation work demonstrates that theoretical analysis is correct and the better resolution is got under the some conditions. Finally, the simulation is made under the condition of noise, the results show that noise affects the resolution of match Fourier transform, but the better resolution is got still under the some conditions. |
