HENSOLDT Presents “TwInvis” Passive Radar for the First Time in Live Operation

New sensor demonstrates its capabilities during ILA in Berlin

Munich/Berlin, 25 April 2018 – HENSOLDT, the leading German sensor solutions provider, is presenting its passive radar system called “TwInvis” to the public for the first time in live operation during this year’s International Aerospace Exhibition (ILA) in Berlin. The new product name “TwInvis” is made up from “twin” + “invisible”, as neither TwInvis itself nor the targets to be detected emit any signals on their own, which means that they are “invisible”. The TwInvis system, which can be integrated into an all-terrain vehicle or a van, does not emit its own signals to monitor air traffic, but simply “passively” analyses the echoes of signals from radio or TV stations.

“Our newly developed, 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 250 kilometres. This was unthinkable even just a few years ago,” said HENSOLDT CEO Thomas Müller. “This will open up completely new options for application in such fields as air defence, the protection of large events or air traffic control.”

Working as mere receivers, passive radar systems detect aircraft by analysing the signals that they reflect from existing third-party emissions. HENSOLDT’s TwInvis system excels with a very precise picture of the airspace covered, which is obtained by simultaneously analysing a large number of frequency bands. For example, up to 16 FM transmitters (analogue radio) plus 5 frequencies used by several DAB and DAB+ transmitters (digital radio) as well as DVB-T and DVB-T2 (digital, terrestrial television) can be simultaneously analysed for the first time. Furthermore, HENSOLDT’s new generation of software will provide unprecedented performance in terms of range and precision of detection.

In civil applications, passive radar systems make cost-effective air traffic control possible without any additional emissions and without using transmission frequencies, which are in short supply. In military applications, the system enables wide-area surveillance using networked receivers, while offering the advantage that passive radar systems cannot be located by the enemy and are very hard to jam. Moreover, no agreement is required with any other public authority, as there is no radiation, which allows the system to be quickly ready for deployment in new locations and to also be used in urban areas. This results in another advantage of the new technology: the system can be used in places where coverage was previously inadequate, in particular for example, in mountainous regions.

TwInvis has already shown what it can do in several demonstrations to military customers, air traffic control organisations and other interested parties. Two TwInvis demonstrators have already been delivered to potential customers in Europe.

HENSOLDT Successfully Demonstrates UAV Countermeasures

Wednesday, December 6th, 2017

Hamburg, 6 December 2017 – As part of a major product demonstration on the Airbus airfield in Hamburg-Finkenwerder, HENSOLDT, the leading independent sensor house, provided proof of the excellent performance of its Xpeller counter-UAV system when it comes to protecting airports and critical infrastructure.


HENSOLDT demonstrated counter-UAV measures using a combination of radar, RF and optical sensors and a targeted jammer to representatives from the police, industrial companies, airport operators and armed forces. For this, the individual elements of the system were positioned in such a way as to ensure optimum surveillance of the whole area. This involved seamlessly integrating Xpeller into the airfield’s infrastructure and proving its compatibility with all the other local systems. Xpeller also managed to reliably detect UAVs starting from different locations. The visitors considered it to be a particular success that the HENSOLDT system was able to reliably detect even extremely small UAVs at a distance of several kilometres and to identify them as threats.

The modular Xpeller product family includes various sensors such as radar, camera and radio frequency detectors as well as direction finders and jammers. Xpeller uses sensors to detect and identify a drone and assess its threat potential at ranges from a few hundred metres up to several kilometres. Based on real-time analyses of the control signals, a jammer then interrupts the link between drone and pilot or interferes with its navigation. The modular Xpeller system concept relies on the selection of individual devices from the product family depending on customer requirements and local conditions.

Hensoldt/Zeiss Tactical

Friday, June 26th, 2009

Optics giant Zeiss has acquired long time Euro tactical scope manufacturer Hensoldt and the firm Hudisco is currently importing them into the US for the first time. Many feel they are comparable to Schmidt & Bender scopes in quality and durability. While pricey, users claim that they have excellent eye relief which makes getting back on target that much quicker.

One of the members of Snipers Hide did an excellent review of the Hensoldt 3-12X56 FF. It is a fact-filled look at the scope and features several videos, one of which is included above. Overall, the evaluation was favorable.
