KOSTET SYSTEM / SPECTRUM INTELLIGENCE
IRIS II
Distributed spectrum monitoring, signal analysis and RF intelligence — designed as an operational measurement system rather than simply a spectrum display.
IRIS II continuously searches selected spectrum, preserves measurement integrity, identifies activity, builds persistent Signal objects and assigns deeper receiver resources when an emission deserves attention. The architecture separates RF acquisition, DSP/analysis, recording and browser presentation so that operator displays never back-pressure or redefine the underlying measurement process.
From spectrum to persistent RF intelligence
Search
Search Receivers cover configured frequency ranges efficiently, minimizing unnecessary retunes and retaining full native-resolution spectrum data for analysis and later presentation.
Detect
DSP measures frequency, bandwidth, level, noise and SNR, producing observations that can become persistent Signals when supported by persistence, recurrence or high-confidence evidence.
Task
Task Receivers can be assigned to selected Signals for closer monitoring, demodulation, IQ/audio recording or other signal-specific processing without interrupting broad search coverage.
Understand
Signal history, transmissions, sessions, recordings, classifications and analytical results remain linked so an operator can move from an RF event to its supporting evidence.
Receiver architecture
IRIS II deliberately separates receiver hardware from receiver role. A capable SDR stream may serve SEARCH, TASK, DF or REFERENCE functions according to mission and hardware capability. The planner considers instantaneous bandwidth, sample rate, retune/settling cost and revisit requirements rather than retuning simply because logical monitoring ranges are separate.
- Hardware/platform-agnostic receiver interfaces for SDR evolution and mixed-site deployments
- Search and Task roles with explicit capability and ownership
- RF-path resources for antennas, filtering, gain/loss and future switching/preselection
- Health monitoring that distinguishes a quiet band from device, stream or DSP failure
Measurement integrity first
IRIS II is designed around a strict principle: the system must not alter the meaning of an RF measurement merely to make a display look stable. Hardware gain, noise floor and absolute spectrum level are not dynamically normalized from live RF content during an ongoing measurement. Any correction is static, deterministic and traceable to calibration or known hardware state.
The server retains the full native-resolution stitched spectrum. A browser reports only the frequency span and physical display resolution it can actually show; server-side presentation then derives an appropriate view without changing acquisition rate, FFT resolution or the underlying stored measurement.
Signals, recordings and band-aware operation
Persistent Signals
Repeated observations can be correlated into logical Signals with state, history, classification and operator policy instead of treating every FFT excursion as an unrelated event.
Band Plans
Editable Band Plans describe channel raster, likely modes, bandwidths and operational expectations. Off-raster emissions remain valid observations and may themselves be analytically interesting.
Recordings
Audio, channelized IQ and raw IQ can be associated with Signals, Transmissions and Sessions together with timing, receiver state and provenance metadata.
Reference data
Known-emitter and transmitter databases can be imported as evidence sources and compared probabilistically rather than forcing uncertain observations into a false positive identity.
Distributed sites, timing and localization
The architecture extends naturally from one monitoring node to multiple Sites. Sites own their local receiver resources and can advertise RF, timing, compute and position capabilities. Future DF and TDOA functions preserve geometry, timing quality, uncertainty regions and contributing sensors instead of reducing localization to an unjustified point on a map.
- GNSS/PPS and timing-quality metadata where required
- TDOA sensor orchestration and centralized cross-correlation
- DF vectors, uncertainty sectors and fused position estimates
- Local autonomy with controlled federation and explicit resource authority
System-of-systems integration
IRIS II is spectrum-centric, while TraceGuard is Target-centric. Through controlled, versioned interfaces, TraceGuard can request monitoring, recording or localization around a Target, area or event. IRIS II can return detections, signal metadata, recordings, timing quality and localization evidence while both systems preserve their own data ownership and provenance.
