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 sutTer high degrees of error, with the FFT the main lobe broadens making it difficult to recognise closely spaced targets. The use of the Short-Time Frequency-Transform (STFT) algorithm is examined. A novel Short-Time MUSIC approach is presented, it can be used to obtain higher time-frequency resolution than STFT method.
