(U) THIS PAPER DESCRIBES AN ON-GOING ATTEMPT TO DEVELOP STANDARD PROTOCOLS AND DATA FORMATS FOR COMMUNICATION OF LOWER LEVEL DATA PRODUCTS BETWEEN MULTIPLE PROCESSING SYSTEMS. THE INITIAL EFFORT FOR THIS WORK HAS BEEN FOCUSED ON THE UNDERSEA WARFARE COMMUNITY, BUT THE PROTOCOLS ARE NOT EXCLUSIVELY APPLICABLE TO SONAR SYSTEMS. DESIGN CONSIDERATIONS ARE GIVEN WITH AN EXAMPLE CLUSTER OF PROCESSING SYSTEMS, SHOWING A DATA MANAGER AND DESCRIBING DATA CLIENTS, AND DATA ...
(U) THIS PAPER PRESENTS AN OVERVIEW OF A DATA ASSOCIATION AND TARGET TRACKING SYSTEM USING A MEASUREMENT-BASED PROBABILISTIC DATA ASSOCIATION TECHNIQUE. THE CONCEPT IS SIMILAR TO THE JOINT PROBABILISTIC DATA ASSOCIATION ALGORITHM, BUT IS MEASUREMENT ORIENTED INSTEAD OF TRACK ORIENTED, REMOVING THE CONSTRAINT THAT EACH TARGET CAN ONLY BE THE SOURCE OF AT MOST ONE MEASUREMENT AT ANY GIVEN TIME, RESULTING IN THE CAPABILITY TO HANDLE INPUT FROM MULTIPLE SENSOR ...
A model for predicting the detection and localization performance of hydroacoustic monitoring networks has been developed. The model accounts for major factors affecting global-scale acoustic propagation in the ocean, such as horizontal refraction from bathymetric features and horizontal changes in sound speed, travel time variability due to spatial and temporal fluctuations in the ocean, and detailed characteristics of the source. In this report, a summary description of the component submodels, ...
