Range resolution improvement for two close targets by using the FM signals

TL;DR

This paper explores enhancing the range resolution for two close targets using FM signals by applying IFFT and MUSIC algorithms, demonstrating that MUSIC with the same FM channel significantly improves resolution.

Contribution

It introduces the application of MUSIC and IFFT algorithms with multiple FM channels to improve range resolution for closely spaced targets.

Findings

MUSIC achieves twice the range resolution of IFFT.

Using the same FM channel, MUSIC outperforms IFFT.

Simulation confirms improved resolution with MUSIC.

Abstract

In this paper, we have focused on the improvement of the range resolution of two close targets by using FM signal. Two algorithms comprise IFFT and MUSIC have been used to reach our goals. On both algorithms, we have tried to improve the range resolution by using more FM channels. The simulation results show that the music method by using the same FM channel gives us a good range resolution twice as well as IFFT method.
