Abstract:A direction finding method for multiple pulse signals received by ground penetrating radar (GPR) is introduced. With band-pass filter,the ultra wide band(UWB) signals have been decomposed into some narrow band signals.Then, the multiple signal classification (MUSIC) algorithm is applied for direction of arrival ( DOA) estimation.Moreover, through processing experimental data,it is found that DOA estimation algorithm can be performed by using only a few high frequency subbands of the incoming signals instead of the whole spectrum of the GPR pulse signals.
