Summary:Applied research on biomedical applications of UWB radar is
targeted to the identification of the possible new devices made possible
by the technology, to the design and development of those devices, and
to the clinical testing of the systems obtained. Applications can be
divided into two main sectors according to the frequency range used. For
the conventional UWB radar microwave region: cardiac biomechanics
assessment; chest movements assessment OSA (obstructive sleep apnoea)
monitors; soft-tissue biomechanics research; heart imaging ("Holter
type" echocardiography); chest imaging. Together with systems for:
cardiac monitoring; respiratory monitoring; SIDS (sudden infant death
syndrome) monitor; vocal tract studying. If an IR laser diode is used as
the antenna, a more common radar is obtained (actually a hybrid between
a narrow band and a wide band radar) which emits a short packet of
electromagnetic waves whose echoes are sampled using conventional UWB
receiver equipped with a PIN photodiode. Possibilities include:
non-invasive biochemical study of soft tissues, non-invasive study of
metabolic processes, and IR spectral imaging
