System for calculating displacement of a sonar array

A computer apparatus determines a highly accurate displacement of a sonar array in real time using multiple processors and data objects. The processors receive multiple sonar pings from a sonar array, instantiate the quasi-unique sonar objects, beamform, and update the objects using time-delay functions. Each object includes properties such as a time of flight value associated with a first ping, time-delay values associated with a second ping, a speed of sound value associated with the pair of consecutive pings, a sonar beam angle value associated with the first ping, and the displacement value. Processing code in each object utilize these properties to update the displacement value and provide it for SAS imaging.
