A Target Tracker Using a Doppler Compensated Correlation Technique.

Abstract

This document is the final research report on the investigation of a mathematical algorithm to do target tracking, using doppler compensated correlation techniques on input time series streams from several passive acoustic sensors. The algorithm was developed and programmed into a testbed on a VAX-750 computer and was tested using simulated time series data generated by the Tetra Tech Broadband Signal Simulator. Algorithm performance proved disappointing due to: (1) Numerical instabilities induced by structural anomalies in the sample signal autocorrelation function; (2) The extreme sensitivity of objective function to choice of signal characteristics and processing parameters; and (3) Computational intensity of the algorithm.
