Radar with the linear frequency-modulated signal may range the target. Its range resolution is decided by the signal frequency bandwidth. This paper proposes an interpolation algorithm based on fast Fourier transform to improve the accuracy of range estimation without increasing the frequency bandwidth. The algorithm application in practice is described. The simulation result of estimation accuracy is also given
