Unique Antenna Design
Spectra Go is a compact, portable, wideband monitoring and direction finding system with an operating frequency range of 20 MHz to 6 GHz. Spectra Go was specifically developed for high performance tactical RF signal monitoring, direction-finding and geolocation applications.
Spectra Go comprises of a packable DF antenna, ruggedised receiver , optional processing unit, and SpectraView software.
The Spectra Go Direction Finding antenna incorporates two antenna bands, each comprised of five elements. The antenna incorporates low noise amplifiers to maximise sensitivity, RF gain control and pre-selection filtering to maximise dynamic range, and RF sequencing to facilitate phase-interferometric direction finding. The antenna is light weight and designed for minimum packing size to facilitate easier deployment logistics. Spectra Go is ideal for man-portable and vehicle borne operations. Elevation of the antenna using masts or buildings of opportunity will enhance detection ranges from static/semi-static locations.
The wideband receiver is packaged in a rugged waterproof housing suitable for the harshest of environments. Spectra Go has two phase-coherent digitising receive channels, each with 100 MHz digitised bandwidth. Advanced integrated digital signals processing enables parallel prosecution of multiple signals of interest whilst maintaining energy and compute resource efficiency.
An optional processing unit extends the base system with long-duration wideband buffering to facilitate after the event ’post-facto’ signal monitoring, recording, direction-finding and geo-location.
