This outstanding radar has been developed by RST Radar Systemtechnik GmbH in
Germany in co-operation with ELBIT Systems, Israel, and the Deutsche
Rettungsflugwacht DRF within the EuropeanTechnology Programme EUROSTARS
Heli-FLR: on the radar
R
ST is a European SME founded in 1992 as a centre for
innovative developments of new radar systems for space,
air, ground and underground applications. RST designed
the high resolution SAR onboard the German satellites, SAR-Lupe,
developed special customer-aided radars like oil and ship
detection SAR for aircraft, helicopter GPR for glacier volume
investigation, airborne altimeter for Arctic topography measurement,
topography radar for blast furnace and GPR for separation
detection in mine drifts for worker safety.
Helicopters, especially in Emergency Medical Services (HEMS)
flights, typically operate under visual flight rules (VFR) and at low
altitudes. Especially when HEMS flights are needed during the
night or under foggy, brownout or whiteout conditions, a lack of
visual ground references can render a pilot susceptible to visual
illusions and other conditions, and can make it difficult to judge
the helicopter’s attitude and actual height above the terrain. The
American National Transportation Safety Board had observed that
many helicopter accidents in the past had occurred during
landing and low level flights. A radar system for detecting
obstacles in the flight path and providing 3D topographic
information on the landing site is, as a result, strongly desired.
The Helicopter Flight and Landing RADAR (Heli-FLR) is an
important development for Horizon 2020 and is supported by the
EUROSTARS programme. This radar provides information to
helicopter pilots during both flight and landing phases in order to
warn about potential harmful obstacles. The radar operates in two
different modes: flight mode and landing mode, is able to operate
in adverse weather conditions (such as fog, snow and rain) and to
detect obstacles through dust and snow blown in the air during
landing and hovering.
Safe flight
The system includes a database in order to store detected
obstacles in the memory. It also includes a visualisation and alert
device. In flight mode, the Heli-FLR warns the pilot of various
obstacles in the helicopter flight path (terrain, buildings, trees,
cables), up to a distance of 1km. An interferometric operations
principle allows the interpretation of the altitude of an obstacle in
the flight path with respect to the helicopter flight altitude.
In landing mode, the Heli-FLR system realises a 360°3D terrain
mapping in order to not only inform the pilot about potential
harmful obstacles, but also to provide him/her with information
about the landing zone (terrain shape, dangerous slopes etc.).
The 360°3D terrain mapping is realised using innovative
interferometric algorithms and provides it to the pilot within less
than two seconds.
The radar resolution of the system is less than 50cm and the
distance measurement is approximately 10cm. The standard
image is a 2D map with colour-coded altitude information.
Shadowed or low-reflectivity areas are shown in black. A 3D
visualisation option using a head-up display is under investigation.
The map example shown indicates the helicopter landing path.
The red line shows the point of entering the landing phase at the
centre and proceeds to the landing point to the left. The height
colour goes from red (high) over yellow, green, blue and finally to
pink (low). The black zones below the flight path are low reflecting
areas (water surfaces) and black zones to the left or on top
represent shadows.
After intensive flight-testing of the prototype in autumn 2013,
under supervision of the user representing partner DRF, a product
will be put on the market by ELBIT Systems that will significantly
increase the safety of helicopter missions.
