Radar Jammers and Where to Find Them

A fully functioning radar provides crucial situational awareness in a wide variety of military settings. And as a key component in the electronic warfare arsenal, it is likely to be the target of countermeasures by opposing forces designed to degrade friendly capabilities, most likely some variety of radar jamming. This can range from straightforward brute-force jamming attempts, where an overwhelmingly powerful wideband RF signal [...]

Tracking Multiple Targets with 3D TDOA

In a recent blog post, we described how 3D TDOA could be used to detect spoofed ADS-B signals from aircraft. And it’s fair to say that the area around an airport is a heavily congested area, with large numbers of planes constantly coming and going. If you’ve got some familiarity with TDOA, though, there might have been something nagging at the back of your [...]

Drone Detection: Myths and Reality

In a rapidly emerging field like drone detection, it can be difficult to separate fact from fiction. At CRFS, we've got years of experience designing and deploying drone detection systems, so we thought we'd do our bit by collecting some of the myths and misconceptions that we’ve come across, and trying to clear them up in this blog. 1) All you need for drone [...]

AIS Spoofing Detection with TDOA

What is AIS? The AIS (Automatic Identification System) is designed to allow ships, boats and other maritime vessels to provide information about their identity, position and heading to other vessels and base stations. It works by broadcasting information using RF signals that can be detected by other users with AIS equipment. This data is transmitted over the maritime channels 87B (161.975 MHz) and [...]

SIGINT capability for Special Operations Forces

SOF (Special Operations Forces) must act with the highest levels of discretion in hostile and often unfamiliar environments. In these scenarios, real-time RF situational awareness is vital for ensuring friendly forces remain undetected and detecting enemy activity. However, this vital capability must be weighed (literally) against the need for forces to be able to carry the equipment and remain agile. So what levels of situational [...]
