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.
