Novel short-time MUSIC in non-linear FMCW GPR signal analysis

Abstract

A novel windowed FFT MUSIC (W-MUSIC) algorithm is presented in the context of using ground penetrating radar (GPR) to detect closely spaced targets under noisy conditions. It is seen to give a better indication of targets than stand-alone FFT and MUSIC algorithms. Distorted signals are analysed, and with the MUSIC algorithm the reported target positions… (More)
