| Abstract: |
In this project Wagner Associates, with Pennsylvania State University/Applied Research Laboratory (PSU/ARL) as a subcontractor, will develop Improved End-fire Tracking Algorithms (IETAs) that will accomplish the goals of this R&D project: I. Accurately resolve closely spaced multiple torpedoes in towed array end-fire II. Accurately track closely spaced multiple torpedoes in towed array end-fire III. Generate accurate and timely alerts for torpedoes in towed array end-fire To achieve Goal I we will utilize advanced techniques for estimating the number of objects in end-fire, and for estimating the bearing and spectrum of each object. To achieve Goal II we will take the detection reports produced the signal processing algorithms and maintain tracks over time using multiple hypothesis data fusion, Gaussian sum tracking and Interacting Multiple Model (IMM) target motion models, and Bayesian association techniques. To achieve Goal III we will utilize enhanced Bayesian inference techniques. |
| Benefits: |
In Phase II we will develop full-scale prototype Improved End-fire Tracking Algorithms (IETAs) that will allow us to demonstrate how powerful end-fire signal processing techniques, multiple hypothesis data fusion, Gaussian sum tracking, IMM motion model, and Bayesian association algorithms and software, combined with non-Gaussian localization and Bayesian inferential reasoning algorithms and software, can significantly reduce the vulnerability of United States forces to torpedo attacks from end-fire. Improved signal processing, data fusion and tracking, and classification technologies such as these are particularly necessary at a time when the United States is facing a sophisticated threat in difficult littoral environments, such as China, Korea, and the Middle East, with reduced resources. More effective torpedo defense techniques will produce more effective operations, conducted at lower risk, resulting in fewer casualties to friendly forces and improved overall United States Navy and Joint Forces effectiveness. |
