The improvement of efficiency of resolution and angular estimation by MUSIC using Fourier coefficient for radar signal processing

摘要

In the radar signal processing, it is assumed that the high-resolution techniques such as MUSIC is able to estimate the direction of the multiple targets which are covered in same radar antenna beam and same range bin separately. In this paper we improve the efficiency of resolution and angular estimation by MUSIC using Fourier coefficient that is the output of the doppler filterbank. The numerical experiments show that proposal method can improve the efficiency even if the signal to noise ratio of targets are low.
