High-resolution goniometry and its applications to localization

OBJECTIVE :

This course aims to present learners with the main concepts of goniometry (estimation of source arrival directions), from the most traditional to the most advanced, by focusing on high resolution techniques so situations can be processed with sources and/or multipath propagations.

COURSE DURATION AND TIMETABLE :

The course lasts 5 days (35 hours) and includes:

  • 15 hours of theory-based learning
  • 14 hours of application
  • 5 hours of Matlab-based demonstration
  • 1 hour of panel discussion

GENERAL APPROACH :

The aim of this course is to show the full potential of high-resolution goniometry with multiple sources and/or multipath propagations and its operational value for many applications requiring the location of transmitters or reflectors in disturbed situations.

The benefit, operational implementation and performance of high-resolution techniques are described for different applications such as HVUHF spectrum control and monitoring, HF single station localization, GPS and Galileo metrology, the location of cellular radiocommunications, sonar, ground radar and localization of intracerebral sources. 

It reconciles theory and practical applications in a balanced way and includes PC demonstrations of implementations and illustrations of processing performance.

PREREQUISITE :

Course level: Advanced

This course is suitable for engineers with basic knowledge of antenna and signal processing.
