INTRODUCTION TO OVER-THE-HORIZON RADAR AND ROBUST ADAPTIVE PROCESSING
August 24, 2018 @ 4:00 pm - 5:00 pm
Skywave OTH radars operate in the high frequency (HF) band (3-30 MHz) and exploit signal reflection from the ionosphere to detect and track targets at ranges of 1000 to 3000 km. The long-standing interest in OTH radar technology stems from its ability to provide persistent and cost-effective early-warning surveillance over vast geographical areas (millions of square kilometres).
As a key element of an integrated ISR system, OTH radar sensors play an important role in cueing higher resolution and more precise line-of-sight ISR sensors, which often have less persistent or more circumscribed coverage. The first part of the lecture introduces the fundamental principles of OTH radar design and operation in the challenging HF environment. This serves to motivate and explain the architecture and nominal capabilities of modern OTH radar systems.
The second part of the lecture describes adaptive processing techniques for clutter and interference mitigation and illustrates examples of their application to real OTH radar data.
