Leading sensor solutions provider HENSOLDT is displaying sensor solutions with a major focus on airborne solutions at the ongoing airshow. The company’s range of sensor solutions can be installed on helicopters, aircraft and Unmanned Aerial Vehicles (UAVs).
Hensoldt is making the maiden presentation of the live air picture of its “TwInvis” passive radar system for the first time in Seoul.
“The highly sensitive digital receivers now make it possible for a single TwInvis system to monitor up to 200 aircraft in 3D within a radius of 250km, which opens up new options for civil and military applications”, says Nathan Manzi, head of Asia-Pacific at HENSOLDT.
The TwInvis system enables large-area surveillance using networked receivers. It offers a decisive operational advantage in that “passive radar” systems cannot be located by the enemy. Several interconnected systems can be deployed to improve target acquisition in mountainous regions and the high level of resistance to disruptive reflections, such as from mountain slopes.
The TwInvis system does not emit its own signals to monitor air traffic, but simply analyses the echoes of signals from radio or TV stations. The system can be integrated into an all-terrain vehicle or a van. The passive radar systems work as mere receivers and detect targets by analysing the signals reflected by them in response to third-party emissions. When deployed in the civilian sector, passive radar can provide air traffic control with an inexpensive supplement to existing sensors, e.g. as a backup for other sensors.
