HENSOLDT’s air traffic control solutions include innovative new developments as the TwInvis passive radar. TwInvis is a passive radar that adds a new dimension to the world of surveillance and situational awareness.
Where conventional radar systems all work using the same principle of emitting signals that are reflected by an object allowing the radar to visualise that object based on the echo received, TwInvis follows a radically different approach: The system uses the countless radio signals which are already in the air from broadcast and TV transmitters and evaluates their echoes when reflected by an aircraft.
It detects up to 200 aircraft in 3D within a radius of 250 km while keeping complete radio silence.
As a primary radar TwInvis does not require any cooperation from aircrafts to locate them. In addition, it operates without emission of own radar signal energy.
Several TwInvis can be linked up into a networked system so as to monitor even larger areas.
Our passive radar technology is also available as an air defence solution:
