Since the global lockdown started in March, attending face-to-face events have proved difficult, if not impossible. It was because of this that we decided to start a series of webinars on RF and Electronic Warfare. We were blown away by the response. We had thousands of people join us from all over the world; from their kitchen tables, spare rooms, barrack blocks and a few actually in their offices!! The webinars helped connect people with information on a range of topics from military spectrum management to RF recording and the principles of RF geolocation. There were plenty of questions from attendees keen to expand their knowledge, many of which have been turned into FAQ’s on the website.

As well as experts from CRFS, we were extremely fortunate to have several guest speakers on the webinars including Decodio, L3Harris and Keysight. Their knowledge and insights added clarity to an array of interesting discussions.

With EW Europe, AOC and many other events now postponed or cancelled this year, webinars are still proving to be an effective way to keep abreast of the latest developments in technology and industry trends. After the success of our Spring and Summer Series, we are now putting together a Winter Series. If you would like to be part of the series, either as a guest speaker or to suggest a topic, please get in touch via [email protected]

If you missed any of the webinars, don’t panic! 😊 We recorded all of them and they are able to view online.

Spring Series


AoA Accuracy – Myths and Legends

AoA (Angle of Arrival) or DF (Direction Finding), is the RF locating weapon of choice for many organizations, in both regulatory and military applications. While an incredibly useful tool, it has its limitations. This webinar will examine the limitations and ways to use the data to ensure you maximize the value of the intelligence you extract from your system.


TDOA – A modern geolocation solution

TDOA (Time Difference of Arrival) has become the modern RF geolocation standard. In this webinar we will cover: how and why TDOA is the new go to RF geolocation method, the fundamentals of TDOA, the strengths / weaknesses to the system and how modern solutions are reducing the limitations.


How to covertly detect and geolocate airborne objects

We examine the technology behind the passive three-dimensional geolocation technique, 3DTDOA and its use in monitoring airborne threats. This webinar will cover: what is 3DTDOA and why now is the time to use it, how to passively extend threat detection range, why the intelligence value of 3DTDOA is significantly greater than normal TDOA and how 3DTDOA can be used to augment existing radar and C4ISR systems.

Big data

How to record and extract signals from BIG RF data

This webinar looks into the challenges in recording I/Q data and finding signals of interest among the terabytes of data. It examines: what is I/Q recording and why would we want to use it, problems associated with recording and analysis of large I/Q data, what to look for when assessing I/Q recorders and technology to simplify the process.

Summer series


COMINT Capture, Decode & Demodulate

It’s not always enough to know a digital PMR signal exists. There is a lot of information conveyed in modern VHF/UHF radio protocols, in addition to the message content, that is essential for COMINT (communications intelligence) purposes and also for civil spectrum monitoring. CRFS are joined by Decodio in this webinar, to outline how signals can be detected and geolocated then captured, extracted, decoded and demodulated to gain an intelligence advantage.

SIGINT in the modern near-peer environment

In this webinar we will discuss some of the denial and deception developments and methodologies that affect modern SIGINT operations, including: Spoofing, Decoys, Wideband, complex or novel signals, Low-profile radars, UAVs, Optics & passive collection, Artificial intelligence and machine learning. More importantly, we will discuss ways to counter these threats to help maintain a tactical edge over potential adversaries.

The Anatomy of an Effective Counter Drone Solution

There are many counter drone/cUAS solutions on the market, each using a variety of technologies and techniques to detect, locate and neutralize any potential threat. But what makes a truly effective solution? In this webinar CRFS are joined by L3Harris ASA and will seek to answer this question along with:  What are the cUAS technology pros and cons? How do you integrate different technologies into a single solution? How can systems deal with COTS v military v modified drones? Plus, we show real counter drone examples from the CRFS and L3Harris systems.

From the field to the lab, best practices in RF signal capture and playback

This webinar looks at the challenges involved in high fidelity signal capture and playback. Topics covered include: the importance of field measurements in the lab setting, using measurements for trouble shooting, quantity v quality, interoperability, how to seamlessly use the data and how to re-create a realistic RF environment. We are joined by Keysight to look at some real-life examples covering Test and Measurement (T&M) and electronic warfare.

Military Spectrum Management

With swaths of spectrum allocated to the armed forces, spectrum monitoring is vital not only to control and manage what is being transmitted but also to control what your RF signature looks like to the enemy. We look at the challenges faced by modern militaries and methods to streamline and automate spectrum management to ensure spectrum dominance.
