Hensoldt has developed a mobile containerised version of its Twinvis passive radar system which provides long-range military airspace surveillance or, in the medium term, in civil air traffic control.

Let’s start off with proof. Below is an animation of a measurement of airplanes and meteors I made using a radar system that I built with a few simple easily available pieces of hardware: two $8 RTL ...

Achieving higher radar accuracy requires multiple radar nodes working together, posing a significant challenge in coherently distributing a shared local oscillator (LO) signal across nodes over long ...

A deployed Maverick M8 radar developed by Silentium Defence. Silentium will collaborate with Lockheed Martin to deliver undisclosed variants from its Maverick suite of radars for Australia's Joint Air ...

SAN FRANCISCO – South Australia’s Oculus Observatory, which opened Dec. 9, houses the first in a planned global network of passive radars to track objects in orbit. Located near the River Murray Dark ...

Like most waves in the electromagnetic spectrum, radio waves tend to bounce off of various objects. This can be frustrating to anyone trying to use something like a GMRS or LoRa radio in a dense city, ...

Passive radar systems have emerged as a transformative technology in remote sensing by exploiting non-cooperative illuminators such as GNSS, communication, television, and radio signals. Unlike ...

Traditional sonar and radar use an echo-based approach, and have been amazingly successful in sensing and tracking vehicles and objects under water, through the air, or even in space. The principle is ...
