The Time Difference of Arrival Blast Sensor is an instrument for measuring critical information from blast events.  Time difference-of-arrival (TDOA), angle-of-arrival (AOA), wave front pressure transients, and wave front velocity are provided to the end-user.  The photo shows the functional breadboard Time Difference of Arrival Blast Sensor mounted on a test stand during Phase I live-fire testing.  A Graphical User Interface (GUI) steps the user through system set-up and sensor operation.  Data is both presented graphically to the user and is stored for additional off-line processing and data retrieval. The Time Difference of Arrival Blast Sensor was originally developed by A2Z Technologies Corporation for the US Air Force under the Small Business Innovative Research (SBIR) program.
