Fundamentals of Data and Information Fusion for Aerospace Systems Online

In This Section


This course provides an overview of the fundamental concepts, frameworks, representative applications, mathematical sketches, and research issues in the field of Data and Information Fusion for aerospace systems. Data and Information Fusion, an adaptive estimation process which spans sensing, tracking and identification, situation assessment, and resource management for decision-making under uncertainty, is becoming prevalent in aerospace systems and is one of the core technologies for enabling autonomous operations. This course is intended for those unfamiliar with the fundamentals and broader implications of these topics and/or are seeking a roadmap and refresher for approaching this topic for aerospace systems research and development. In addition to the fundamentals, a high-level introduction to Systems Engineering of Data and Information Fusion will be provided for design, development, implementation, integration, and validation of these technologies for real-world aerospace applications. Furthermore, role of Data and Information Fusion in practical aerospace applications such as missile defense, command-and-control, air-traffic control, remote-sensing, and autonomous vehicles will also be discussed.

Learning Objectives:

  • Define fundamental concepts of Data and Information Fusion
  • Summarize and illustrate the Multi-Level Reference Model of Data and Information Fusion
  • Develop Networked and Distributed Sensor and Data Fusion Architectures
  • Recognize Functional Tradeoff Issues and the nature of Mathematical Techniques
