1. A method of determining a bodily characteristic comprising:
collecting sets of reflection data for a sequence of ultra-wideband (UWB) pulses transmitted via a UWB sensor comprising at least one transmitter antenna and at least one receiver antenna positioned on a body of a user;
determining parameters based on the sets of reflection data, the parameters determined from reflection profiles based upon the reflection data for the sequence of UWB pulses; and
determining a fluid level content of lung tissue based upon the parameters, wherein determining a fluid level content of lung tissue comprises generating an ongoing and continuous trend of congestion, including correlating measured bulk dielectric strength of targeted areas of the lung tissue to assess and quantify both instantaneous fluid content and changes in fluid content and tracking the congestion in a plurality of stages, wherein an alert is provided in each stage of the plurality of stages.
