1. A method for analyzing blast exposure data, the method comprising:
receiving a plurality of sets of raw pressure data, each set of raw pressure data of the plurality of sets of raw pressure data collected by a respective blast sensor of a plurality of blast sensors;
for each set of raw pressure data of the plurality of sets of raw pressure data:
applying one or more filters and a baseline shift to the set of raw pressure data to generate a set of filtered data, the baseline shift removing a bias from the set of raw pressure data;
identifying one or more spurious features within the set of filtered data;
responsive to identifying the one or more spurious features, flagging one or more portions of the set of filtered data that include the one or more spurious features;
removing the one or more flagged portions of the set of filtered data;
automatically identifying one or more waveform features within the set of filtered data;
grouping two or more sets of filtered data from respective sets of raw pressure data of the plurality of sets of raw pressure data into a blast event data grouping based at least in part on the one or more identified waveform features; and
estimating an incident blast overpressure based on the two or more sets of filtered data within the blast event data grouping.
