Abstract
Radar with the linear frequency-modulated signal may range the target. Its range resolution is decided by the signal frequency bandwidth. This paper p roposes an interpolation algorithm based on Fast Fourier Transform (FFT) to improve the accuracy of range estimation without increasing the frequency bandwidth. Algorithm application to practice is described. The simulation r esult of estimation accuracy is also given.
