GEW showcasing new direction finder at AAD 2018


GEW is showcasing at Africa Aerospace and Defence (AAD) 2018 exhibition for the first time what it says is its most advanced HF direction finder to date, the MRD600.

This is a high-speed, ultra-wideband direction finder designed for extremely fast and accurate spectrum monitoring and direction finding, GEW said. GEW is the spectrum dominance business line of Hensoldt South Africa.

With its 30 MHz instantaneous bandwidth, the MRD600 directly samples the entire HF spectrum, resulting in an extremely high DF scan-speed of more than 15 GHz/s. This high capture-rate leads to a very high probability of detection of even the fastest frequency-agile and LPI signals.

The MRD600 can be used for stand-alone, single-operator spectrum surveillance solutions or as part of an integrated signals intelligence or spectrum monitoring system. When combined with GEWTM receiver and automatic signal-analysis sub-systems, the entire HF frequency band can be buffered and automatically processed for both tactical and strategic collection systems, GEW said.

Designed for use with static and deployed HF antenna arrays, the MRD600 is suited for fixed and semi-mobile, or transportable COMINT and spectrum monitoring sites.

The high performance of the MRD600 is complemented by the use of large-aperture interferometric L-array antennas in either 85 m or 125 m configurations, which allows for sub-one degree accuracies and Single Site Location algorithms. For compact deployments, the MRD600 can also be used with a Watson-Watt antenna configuration.

The MRD600 is displayed at the HENSOLDT SA stand at 3CE19, where the HENSOLDT SA team can provide more information on its advanced functionality.
