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 [...]

5 Ways that RFeye Mission makes life easier for Spectrum Managers

As the amount of military hardware reliant on RF communication increases, so too does the spectrum manager’s workload, with the need to juggle requirements for spectrum allocation, keep track of in-progress tests and produce post-testing reports. So how can you fight back against this increasing complexity? By automating tasks using RFeye Mission. 1) Simplified scheduling RFeye Mission lets you directly import database schedules such [...]

RFeye for EMCON

"I'm up. They see me. I'm down." Ground forces assaulting forward learn to minimize the physical signature they give to adversaries. Many of our U.S. military customers are familiar with this refrain for minimizing a Soldier or Marine's individual profile when assaulting forward toward an objective. We understand that an enemy combatant on the ground can see us because, in a direct [...]

ADS-B Spoofing Detection with 3D TDOA

ADS-B Basics Automatic dependent surveillance-broadcast (ADS-B) is a surveillance technology currently being introduced in the US (Next Generation Air Transportation System), Europe (Single European Sky ATM Research) and across the globe. It functions as a replacement for secondary surveillance radar, and possibly even to replace primary radar in future, for air traffic monitoring and control. It requires planes to determine their current position using [...]

Augmenting Radar Systems with 3D TDOA

Radar is a tried and trusted method of monitoring aircraft activity in the surrounding area. It is also, in certain circumstances, a blaring beacon advertising its own location to enemy forces. Let’s have a look at how 3D TDOA can be used to circumvent this problem, when deployed as a complement to radar systems. Types of Radar System First of all, we’ll need to have [...]
