An exploration of Passive Radar

Passive radar may be defined as radar that makes use of existing transmissions – such as broadcast, communications or radio-navigation signals – rather than a dedicated radar transmitter.

Such systems have a number of advantages, including covertness, low cost, and no need for additional spectrum. The earliest experiments go back several decades, but for many years the concept was not much more than an interesting research topic.

That situation has changed significantly in the past five years or so. There has been a step change in the maturity of the technology, and several commercial companies have built and demonstrated systems with high performance.

This is due to a number of factors, including ever-greater spectrum congestion, and the widespread use of digital transmissions.

A defence business website estimates that the civil and defence market for passive radar will exceed US$10bn over the next decade.

The presentation will cover some of the key developments, examples of practical systems and results, and some speculation on the future of the subject.

About the ICCS online seminar series

The ICCS seminar series is designed to bring together members of our community who are currently away from our home in Bloomsbury and distributed across the world. The Seminars are being curated to provide academic exploration and inspiration, offering insights into a range of topics surrounding communications and connected systems. Topics will either explore subjects close to the work of our academics or introduce wider concepts from experts in the global academic and industrial community.

If you wish to suggest a future topic or speaker please use the link below, speakers could be from academia, industry, within ICCS/UCL or from further a field.


The seminar will begin with a presentation aimed at a technical audience, but at a level that will be accessible to those from a range of engineering disciplines. Speakers have been asked to end their presentations with a technical challenge or delving deeper into the content to engage those more invested in the topic. 

The seminar series is designed to offer a compact exploration of ranging topics and is therefore short in format. The presentation will run for 15 - 30 minutes, followed by 15 minutes of questions.
