Abstract

In the process of collecting FMCW, we need to ensure the accuracy of FMCW. Therefore, there must be certain requirements for the accuracy of the collected signal. Traditional FFT has the disadvantage of spectrum leakage and is limited by the accuracy of FFT in the process of spectrum refinement, resulting in low accuracy of the collected signal. Therefore, the phase invariance of all phase FFT algorithm is used to solve this problem. In this paper, the Simulink model of all phase FFT in MATLAB is built. The model is used to realize the function of all phase FFT, and the obtained FM continuous wave signal is modulated by all phase FFT to obtain the required signal. Compared with the program in MATLAB, the system is simple and easy to understand, and can be more practical, which provides a strong reference evidence for the implementation of the subsequent hardware system.
