Abstract

High resolution signal parameter estimation is a significant problem in a wide range of applications particularly for radar imaging and computational electromagnetics. In this paper, we present a comprehensive study of a few notable high resolution techniques for parameter estimation like MUSIC, matrix pencil and RELAX based upon numerical simulation and compare their estimation performance. The result shows that RELAX provides better estimates for closely spaced signals especially for low signal-to-noise ratio (SNR).
