ATI's Multi-Target Tracking and Multi-Sensor Data Fusion course


Share |

Summary:

    Technical Training Short On Site Course Quote

    The objective of this course is to introduce engineers, scientists, managers, and military operations personnel to the fields of radar tracking, data fusion and to the key technologies which are available today for application to this field. The course is designed to be rigorous where appropriate, while remaining accessible to students without a specific scientific background in this field. The course will start from the fundamentals and move to advanced concepts. This course will identify and characterize the principal components of typical tracking systems. A variety of techniques for addressing different aspects of the tracking data fusion problem will be described. For example, different techniques are required for the assimilation of "time-late" data than those used for "real-time" data. Real world examples of data fusion systems used by both the Navy and the Marines will be presented and discussed. This course will also use specific illustrative examples to show the tradeoffs and systems issues between application of different techniques.

Instructor:

    Stan Silberman is a member of the Senior Technical Staff of the Applied Physics Laboratory. He has over 30 years of experience in tracking, sensor fusion, and radar systems analysis and design for the Navy, Marine Corps, Air Force, and FAA. Recent work has included the integration of a new radar into an existing multisensor system and in the integration, using a multiple hypothesis approach, of shipboard radar and ESM sensors. Previous experience has included analysis and design of multiradar fusion systems, integration of shipboard sensors including radar, IR and ESM, integration of radar, IFF, and time-difference-of-arrival sensors with GPS data sources, and integration of multiple sonar systems on underwater platforms.
