Patent ID: 7725150

Claim:
A process employing ultra wideband radar return signals to extract physiological data from one or more bodily organs or physiological processes of a patient, said process comprising: generating a baseband pulse train; transmitting an emitted signal from a first antenna as an ultra-wide band spectrum signal, wherein the emitted signal comprises a series of low voltage, short-duration pulses triggered by the baseband pulse train; outputting a delayed version of the baseband pulse train from a delay range comprising an electronically controlled range gate; receiving reflections of the emitted signal at a receiver connected to a second antenna, wherein the receiver is triggered by the delayed version of the baseband pulse train; processing the reflections received by the receiver to generate a first matrix of time-sampled reflection values at various depths; converting the first matrix of time-sampled reflection values into a second matrix and extracting physiological data from the second matrix using frequency spectrum analysis and statistical filtering.
