ILA 2018: Rohde & Schwarz showcases SDAR

26 April 2018

Rohde & Schwarz (R&S) has taken the opportunity at the ILA Airshow in Berlin to unveil its software defined radio (SDR) portfolio with the new R&S SDAR (Software Defined Airborne Radio).

Markus Dolfen, director of sales avionics, told Jane’s that the service component architecture (SCA) of the R&S SDAR is partially based on the existing R&S SDTR vehicle transceivers that were introduced back in 2012, but also incorporates the latest hardware components and manufacturing processes.

The R&S SDAR is a V/UHF transceiver operating in the 30-512 MHz range and is enclosed in a standard ARINC 600 housing, which enables it to be fitted in a diverse range of platforms, including fixed and rotary wing aircraft and unmanned aerial vehicles (UAVs).

The radio’s architecture is based on the international SCA standard, which supports the development and use of customised waveform and encryption algorithms. Options available for porting include the R&S HDR family of anti-jam (narrow and wideband variants) waveforms with throughput of 110 and 630 kbps respectively, as well as the R&S HDR Wideband waveforms with up to 2.1 Mbps at 500 kHz.

Other waveforms certified for the R&S SDAR are the R&S SECOS (enabling interoperability with M3xR installed base), civilian ED23C (ATC), and M.489-2 (maritime VHF). The company will offer R&S SDAR customers a support toolset, including the R&S WFDE (Waveform Development Environment), to develop radio applications such as crypto and waveform to individual national specifications.

The radio features a MIL-STD-704F fixed 28 V DC input and variable power output of 20-40 W depending on selected modulation such as AM/FM and QAM.
