Augmenting Border Security and Defence With RF Sensor Technology

Adam Williams — Wed, 10 Jul 2024 14:41:32 +0000

Together with cameras and radar, RF technology is an essential element of border security and defence. Its distinct advantage is the ability to provide passive surveillance and early warnings of potential criminal activity, or threats to national security—which can then be closely investigated and addressed with the appropriate resources.

A CRFS Guide to Strengthening ISR Capabilities with RF Sensor Payloads in Unmanned Aerial Vehicles

Adam Williams — Wed, 10 Jul 2024 14:36:26 +0000

Unmanned aerial vehicles (UAVs) range from small quadcopters to high-altitude long endurance (HALE) systems that can conduct extensive missions. As UAVs are highly configurable, militaries, border security agencies and the police need the right mix of sensors to meet the requirements for a wide array of different missions day, night, and during adverse weather conditions.

Spectrum Monitoring and Geolocation Systems

Elli Karampela — Sun, 26 May 2024 23:00:50 +0000

In the past few years, the exponential growth of wireless devices has created significant challenges for spectrum regulators.

Principles of Geolocation Techniques

Elli Karampela — Sun, 19 May 2024 23:00:33 +0000

Geolocating RF signals can appear complex, with a plethora of available techniques (AoA, TDOA, FDOA, & POA).

Passive Geolocation with 3D TDOA

Elli Karampela — Sun, 12 May 2024 23:00:18 +0000

In this whitepaper, we will focus on the passive technique known as Time Difference of Arrival (TDOA), which uses the time difference between the receipt of signals at spatially separated receivers to determine the location of the source.

Key Radio Parameters for Spectrum Monitoring Receivers

Elli Karampela — Sun, 05 May 2024 23:00:46 +0000

Radio receivers for spectrum monitoring are at the heart of spectrum management operations.

Angle of Arrival/Direction-Finding Techniques

Elli Karampela — Tue, 23 Apr 2024 14:15:05 +0000

Angle of Arrival (AoA) or Direction Finding (DF) techniques are perhaps the most widely used ways to geolocate radio frequency signals.

Advanced Geolocation Capabilities

Elli Karampela — Tue, 23 Apr 2024 14:11:13 +0000

In this paper, we are going to look at how standard AOA (Angle of Arrival), TDOA (TimeDifference on Arrival) and POA (Power on Arrival) geolocation techniques can be improved upon by using advanced signal processing techniques as implemented by RFeye® software and hardware.

A Guide to RF Geolocation Techniques

Elli Karampela — Tue, 23 Apr 2024 14:09:39 +0000

Faced with this reality, it is paramount to understand the spectrum and the RF environment to know who is operating, who belongs, and who does not.
