Portable ultra wideband radar for monitoring chest fluid level and cardiopulmonary function

摘要

Provides various examples of portable body monitoring using ultra wideband radars.For example:How to determine physical features isFor continuous ultra wideband (UWB) pulses transmitted via UWB sensorsSet reflection backscatter data andCollect corresponding calibration measurements from calibration channels andBased on a set of reflection backscatter dataDetermining the reflection coefficient for each tissue interfaceBased on reflection coefficientIncluding determining body fluid level capacity of lung tissue.The reflection coefficient can be determined from the reflection curve based on reflected backscatter data for its continuous UWB pulses and corresponding calibration measurements.The UWB sensor may include an array of transmit (TX) and receive (Rx) antenna pairs positioned on the body of the user.The reflection curve can be associated with a model of tissue layers in the body between the UWB sensor and the lung tissue.Diagram
