SpectraStar™ Advanced Digital Spectrum Monitoring System

A leader in advanced RF Spectrum Management and Cognitive Radio systems, STAR-H has developed unique hardware and software systems for monitoring, managing, recording, and measuring the ambient RF spectrum in real time.

SpectraStar™ provides high performance spectrum monitoring and activity archiving at a remarkably economical price.  Using custom developed Windows software applications and PCI-based high speed A/D data acquisition along with a unique wideband high speed RF/IF downconverter, the SpectraStar™ is the optimal solution for inexpensive high performance monitoring of radio signal activity in the HF, VHF, and UHF spectrum.

Wideband Coverage
STAR-H's hardware and software can monitor spectrum occupancy from DC to 450 MHz standard or 1 GHz optionally, with expanded 3 GHz coverage coming soon.  Realtime continuous monitoring of 40 MHz of contiguous spectrum with 12.5 kHz resolution and scan rates up to 4200 GHz/second is possible.  Wider bandwidths are covered in sequential blocks with scan rates determined by resolution and bandwidth requirements. Matching compact and covert wideband antenna systems for monitoring are also available.

Monitor Realtime Pulse and FH Signals
STAR-H's systems are designed to identify short pulse and fast frequency hopping systems such as SINCGARS and other systems.  STAR-H's system can track FH units operating as fast as 2700 hops per second, and can identify systems operating even faster.

This sequence shows the tracking of a SINCGARS frequency hopping radio transmission over three consecutive hops.

Demodulation and Data Analysis
STAR-H's system allows the archiving of spectrum occupancy data for later analysis, or the realtime identification of underutilized spectrum for on the fly frequency allocation for military or civilian operations in combat, security environments, sporting events, or any other situation requiring realtime awareness of spectrum occupancy.  STAR-H's proprietary empirical prediction software can provide probabilistic ranking of unoccupied spectrum channels for immediate reallocation while maintaining co and adjacent channel interference specifications. 

Signal demodulation using onboard IQ demodulation allows AM, SSB, FM, PM, FSK, and digital demodulation to be easily performed on any identfied signal.  The modular nature of the system allows as many receiver channels as desired.

Because the system performance is based on a flexible DSP and FPGA based signal acquisition system, Star-H is able to customize versions for almost any application.  Contact Star-H for additional information.
