In conjunction with ESG Elektroniksystem and representatives of the German armed forces (Bundeswehr), Rohde & Schwarz has performed a series of tests on the CH53 and Tiger helicopters, as well as on the rotary wing UMAT R-350 UAV from ESG.
The stationary tests, conducted at the Bundeswehr Technical Center for Aircraft and Aeronautical Equipment (WTD 61) in Manching, were designed to examine the influence of rotors on radio waves.
This aims to ensure piloted and unpiloted rotary-wing aircraft of the Bundeswehr can send data links through one or more rotor planes.
According to the company, the tests demonstrated the resilience of radios against level drops, phase shifts and diffraction at rotor blades' edges.
Digital voice and data transmission also withstood disruption at the highest sensitivity.
A large data set 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," Mathias Pauli, vice president, secure communications at Rohde & Schwarz, said.
"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."
