Abstract

In this chapter, we have presented a baseband receiver that allows an analytical treatment of the output of a SCAT-like processing and that can also be applied to RF signals. The output of the Baseband SCAT (BSCT) has been compared analytically with that of a conventional matched filter for two closely spaced scatterers. Results have shown that a bat-inspired spectrogram transformation can provide better range resolution performance than that of a conventional matched filter. The results have been derived analytically and then verified with a set of laboratory experiments at ultrasound, using phantom echoes and real targets, to assess the robustness of the algorithm with respect to operational hardware limitations and propagation effects.
