Full Field Processing (FFP) Program

Abstract

Our long term goal is to quantify via measurement, the advantage of three dimensional arrays for detection, tracking and classification of surface ships and submarines and to extrapolate these results to other environments and conditions. This is to be accomplished using adaptive full field methods using narrowband and broadband array processing, followed by tracking algorithms which are similar to the maximum likelihood method constrained by certain track considerations. More specifically, our objectives are to measure and understand the range-frequency limits of full field processing and the gain that can be achieved against wind and shipping noise in a dynamic environment and compare those results to that obtained with a horizontal line array. As part of this analysis we seek to compare the performance of the FFP array with a horizontal line array (HLA) in terms of signal, noise and array gains. In addition to the results cited above which a based on CW measurements, we seek to determine how broadband frequency combination and tracking can improve detection performance and classification.
