Webinar: Understanding over the horizon low frequency radar

Webinar: Understanding over the horizon low frequency radar

This session will discuss the differences between a traditional line of sight radar and an Over The Horizon (OTH) HF radar. We will discuss the drivers behind the revival of interest in OTH radar, partially driven by the threats from hypersonic missile and stealth-technologies.

The session will review the principles of long-range HF propagation, the sources of interference and ionospheric effects. We will highlight operational OTH radars including the US Relocatable Over the Horizon Radar (ROTHR) and the Australian Jindalee Operational Radar Network (JORN). The session will conclude with an overview of the challenges of OTH radar from a Research, Development, Test & Evaluation (RDT&E) viewpoint, modelling and simulation tools, channel sounding, coherent transmission and calibration, the use of COTS power amplifier and coherent reception.

In this webinar, you will learn how to/ more about:

  • Why is HF radar enjoying renewed interest?
  • Principles of operating in the HF band
  • Examples of operation OTH radars
  • Challenges of operating OTH radars
