Abstract
Various examples related to mobile bodily monitoring using ultra-wideband radar are provided. In one example, a method for determining a bodily characteristic includes collecting sets of reflected backscatter data for a sequence of ultra-wideband (UWB) pulses transmitted via an UWB sensor, and a corresponding calibration measurement from a calibration channel; determining reflection coefficients for each tissue interface based on the sets of reflected backscatter data; and determining a fluid level content of the lung tissue based upon the reflection coefficients. The reflection coefficients can be determined from reflection profiles based upon the reflected backscatter data for that sequence of UWB pulses and the corresponding calibration measurement. The UWB sensor can include an array of transmit (TX) and receive (RX) antenna pairs positioned on a body of a user. The reflection profile can be associated with a model of tissue layers in the body between the UWB sensor and lung tissue.
