Army researchers built the sensor, which can sample the radio-frequency spectrum — from zero frequency up to 20 GHz — and detect AM and FM radio, Bluetooth, Wi-Fi and other communication signals.
A new quantum sensor can analyze the full spectrum of radio frequency and real-world signals, unleashing new potentials for soldier communications, spectrum awareness and electronic warfare.
The metal detector circuit shown here must represent the limits of simplicity for a metal detector, yet the design works surprisingly well. It uses just. ... As shown, the metal detector gives a ...
Dual frequency detection is a technology utilised by the Pyronix break-glass detectors to filter through noise to focus solely on the frequencies of breaking glass, to optimise detection and generate ...
Frequency output is proportional to the velocity of the detected object; the maximum speed for the sensor is only 14.5 mph (22.7 km/h), so don’t expect to be tracking anything too fast.
New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection ...
A new sensor that can detect the entire radio spectrum could play a big role in the future of electromagnetic warfare and communications. In January, David Meyer, Paul Kunz, and Kevin Cox with the ...
However, the research team in Delft developed a circuit that can actually detect these chunks of energy in radio frequency signals, opening up the potential for sensing radio waves at the quantum ...
Lightning strikes are quite high energy events, and release plenty of radio frequency energy when they go off in the atmosphere. This makes them easy to detect, and the magnitude of the energy rele… ...
