Abstract

This workshop delivers a comprehensive, end-to-end virtual modelling framework that seamlessly connects theoretical foundations with real-world radar and communication system implementation.

Participants will dive deep into cutting-edge radar system modelling and rigorous communication system performance evaluation, using simulation methodologies that faithfully replicate the complexity of real-world signal environments with exceptional fidelity.

The workshop culminates in a forward-looking exploration of how Large Language Models (LLMs) are emerging as powerful tools for next-generation radar and communication system design.

Attendees will walk away with:

  • Mastery of advanced simulation methodologies that mirror the complexity of real-world signal environments
  • Experience with high-fidelity radar and communication system modelling tools
  • Insight into how LLMs are reshaping the future of system design

This workshop also lays a powerful foundation for Electronic Warfare (EW) Analysis, equipping participants with the skills and frameworks needed to tackle sophisticated EW challenges head-on.
