Compact Wide Band Spectrum Monitoring Receiver System
SGX-SPIRE is a compact wide band Spectrum Monitoring Receiver System is designed to search, monitor frequency spectrum in HF/VHF/UHF bands. With the help of its fast scanning, wide band receiver capable to recognize and log the activity in the frequency spectrum. The system using its own multi-channel monitoring receiver to demodulate, record, analyze and decode the received signal, can measure the bearing of the incoming radio signal and with its own fast scanning receiver can continuously monitor the spectrum activity. Every parameter can be adjusted by the operator on the local terminal GUI in case of stand-alone operation or if connected through TCP/IP network, can be operated remotely. • Wide frequency coverage from 1MHz up to 6000MHz • Wideband signal processing up to 20MHz real-time bandwidth • Built in direction finding processor for all the spectrum components • Full or reduced bandwidth record and playback capability • Spectral emission search with up to 20GHz/sec scanning speed • Automatic channel scanning with up to 25k predefined channels • Hand off receiver pool with up to 16 fully independent channels • Narrowband monitoring and recording with 12.5-250KHz bandwidth • High probability signal classification and decoding functionality Signals and scenarios can be recorded continuously limited only by the size and speed of the internal hard disk. When playing back these recorded files all measurement and monitoring functionality such as marker- and bandwidth measurements, zoom and waterfall displays are available in the same detail as if receiving live antenna signals. Snapshot recordings of the complex baseband (I/Q) data at 20 MHz bandwidth can be performed using an onboard memory module. The system can be controlled in manual or full automatic mode. In automatic mode comprehensive scans can be performed. The frequency scan can be defined by start frequency, stop frequency and dwell time. Arbitrary frequency areas can be excluded from the scan. A memory scan can be performed by predefining individual channels. Channels can be grouped for specific sub-scans. The SGX-SPIRE as a versatile and highly sophisticated receiver platform is the ideal solution for a multitude of both civilian and military applications such as: • emission compliancy testing • spectrum allocation analysis • automatic signal detection • search, intercept and emitter location • strategic and tactical reconnaissance systems • data acquisition, classification and preprocessing • threat recognition • offline processing and technical analysis • finding unwanted transmitter sources’s location by public authorities
