Abstract

Using low microwave frequencies (up to 2 GHz) through a monostatic analysis, the signature of a metallic target behind a thick brick wall is detected and resolved. An alternative approach using cepstral analysis is introduced for resolving the target's signature from that of the wall, which is particularly beneficial at close proximity when both signatures merge in the time domain. The use of lower frequencies combined with the monostatic analysis provides for greater flexibility in operational requirements, frequency spectrum constraints, and cost of transceivers, as well as a better wall penetration of the electromagnetic waves. Additionally, the introduction of the cepstrum-domain analysis opens a new window for detection and identification research in the field of through-wall remote sensing.
