The R&S M3TR, a software-defined radio system with open architecture, provides a unique approach to joint, combined and coalition operation using line of sight (LOS) and beyond line of sight (BLOS) transmission. The R&S M3TR represents a new generation of affordable, high-performance digital radios, that meet these stringent inter operability needs. The R&S M3TR is designed for use with military and civilian legacy radios/ wave forms. State-of-the-art technology and the innovative system architecture of the M3TR provide flexible growth capability through pre planned product improvement (P3I) and enable the customer to benefit from future technologies through the evolutionary acquisition process.

Multiband

For applications using of various services and networks, different types of radio units were previously required. The R&S M3TR covers the whole spectrum from the HF to the UHF band, and thus allows interoperability as well as uniform and reduced inter-service logistics. The frequency flexibility of the R&S M3TR meets various national and international regulations, thus providing global operation in changing missions and environments.

A basic radio station consists of the transceiver with two radios in a vehicular installation but can be equipped for full net integration. Each radio can also be connected to RF amplifiers that increase output power to 50 W in the VHF and UHF bands (30 MHz to 512 MHz) and 150 W in the HF band (1.5 MHz to 30 MHz). If these power amplifiers are used, a single R&S M3TR radio (R&S MR3000H or R&S MR3000U) will cover the whole frequency range from 1.5 MHz to 512 MHz without any gaps.

Multimode

A software radio not only offers flexible network solutions but also integrates existing national or company standards in a single unit. Due to optimized protocols and waveforms, the R&S M3TR attains highest throughput rates for digital voice, data, video and position location.

Military waveforms

Available or prepared for the following:

• BLOS: ALE to MIL-STD-188-141B, App.A, AM, FM, SSB, STANAG 4285, SECOM-H
• LOS: SECOM-V, HaveQuick I/II

High data rate waveforms

Available or prepared for the following:

• Beyond line of sight (BLOS): R&S MR3000H/U HF modem waveforms for fixed frequency and frequency hopping
• Line of sight (LOS), VHF/FM, V/UHF up to 72 kbps, open for future extensions
• Civil waveforms, prepared for the following: VHF ATC (25/8.3 kHz), VHF AM, VHF/FM public services (12.5/5 kHz)

Security

• Embedded COMSEC
• Compatible with various external COMSEC devices

Digital voice

• Vocoders adapted to mode of operation and bandwidth

Multirole

The multirole features of a software-defined radio are mainly determined by its ease of integration into tactical communications networks. In addition to its use as a functional terminal in the respective subnet, e.g. CNR or PRN, it can also act as an interface between the individual subnets. The R&S M3TR can be used on diverse platforms and features interfaces to fixed networks such as ISDN, WAN, LAN, as well as intelligent gateway and relay functions, such as auto routing of a selective call to subscribers outside the network.

• CNR - combat net radio
• PRP - packet radio services
• RAP - radio access point
• REN - range extension node
• GPS: time and position location
• Gateway/interface:
• to WAN/LAN
• between HF/VHF/UHF nets

Embedded EPM

The newly developed SECOM (SECOM-V for the VHF and UHF bands, SECOM-H for HF) with its high hop rates and secure synchronization is setting standards. It ensures powerful protection against detection, interception, jamming and spoofing. Within one SECOM V net, several subnets and sublinks can be established simultaneously in point-to-point, point-to-multipoint and broadcast mode. Network synchronization and access can be planned and controlled individually for each user. Methods such as late net entry or hailing are available for this purpose. The COMSEC part of the SECOM EPM method is based on a crypto algorithm developed by Rohde & Schwarz. The method uses key lengths of up to 256 bits (approx. 107 variants). The keys required for the EPM method can be distributed by means of a KDD (key distribution device) or directly from a PC. All keys are encrypted and the deciphered original is present only in the read-protected security processor. Crypto units to NATO standards or from other manufacturers may be used as an external option.

Detachable frontpanel

The R&S MR3000H belongs to a new family of high-performance digital radios covering the HF and VHF/FM band in a single unit. Thanks to different high-speed data modes and protocols as well as different antijam modes for HF and VHF/FM, it perfectly integrates into tactical communication networks.The radio is software-configurable and reprogrammable including pre planned product improvement (P³I).

All members of the R&S M3TR family are based on one mechanical platform, with a common logistic concept and one man machine interface (MMI).
