Abstract
A target tracking sonar system associated with a moving platform incorporates a Kalman filter model and a false target detection capability characterized by comparison of the estimated and actual acceleration to produce an error value which, if greater than a predetermined threshold, namely the product of one half the estimated acceleration and the internal between periodic acceleration updates, generates a signal condition to flag the false target.
