Munich, December 1, 2021 –
Rohde & Schwarz, together with ESG Elektroniksystem- und Logistik-GmbH and
representatives of the German armed forces (Bundeswehr), successfully carried out
stationary tests on the premises of the Bundeswehr Technical Center for Aircraft
and Aeronautical Equipment (WTD 61) in Manching. The
influence of rotors on radio waves was tested on two types of helicopters, operational
with the Bundeswehr, the CH53 and Tiger, as well as on the rotary wing UMAT R-350
UAV from ESG. Piloted and unpiloted rotary-wing aircraft of the Bundeswehr need
to be able to send data links through one or more rotor planes, where interference
can by caused by rotor blade modulation. The successfully completed tests demonstrated
how robust the radios are against level drops, phase shifts and diffraction at rotor
blades' edges; while digital voice and data transmission was possible at the highest
sensitivity. In addition, a comprehensive set of data was collected to develop robust
waveforms for broadband data transmission in the SHF frequency band.
"Equipping today's armed forces with secure, up-to-date solutions for radio networking
is essential for command and control effectiveness during deployment," explains
Mathias Pauli, Vice President Secure Communications at Rohde & Schwarz. "These
tests, on behalf of the German armed forces, investigated the influence of rotors
from different types of helicopters on radio links. We achieved the goal of proving
the suitability of the existing VHF/UHF and 5 GHz radio systems for operational
deployment."
