SELF-CALIBRATING SHOOTER ESTIMATION

摘要

This invention relates to a method for compensating for sensor degradation in a multi-sensor shooter detection system, comprising the steps of: determining a time of arrival of shockwaves produced at the sensors by incoming shots; performing a least-squares regression for the shockwave arrival times at the sensors to determine a time residual; observing a contribution of each of th e sensors to the time residual for a plurality of shots; and compensating for sensor degradation by assigning a weight for each sensor, said weight being inversely proportional to a contribution of said sensor to the time residual.
