UVS Detector

Under active development. UVS Detector is approaching public release. Full technical documentation and beta builds — by separate agreement (NDA) for verified partners.

What it is

UVS Detector is an SDR-based platform for hands-on radio-spectrum work in the field. The cycle is: sweep, detect, classify the modulation, identify the emitter, and where possible decode the payload. All driven from a single operator-grade UI — 22 panels with preset layouts for different tasks.

Processing pipeline

• Sweep — configurable SweepPlans (Full / Targeted / Stare / FollowFHSS), stitched wide-band PSD, waterfall, heatmap, named band presets.
• Detect — noise-floor tracker, CA-CFAR, peak grouping, burst segmentation, hit aggregation, dedicated FHSS tracker, JSONL detection log.
• Classify — feature stack (bandwidth, cumulants, α-SCF, cyclostationary features, chirp, fingerprint) and a fusion classifier combining rules, EVM probe, and ML fusion. 24 modulation classes.
• Identify — Bayesian fusion of frequency, modulation class, fingerprint and regional spectrum allocations (ITU r1/r2/r3 + national rules) against a database of 329 emitters (226 civilian + 103 hostile). A separate layer — the hostile-intel overlay for RU tactical radio and EW, enabled in the appropriate operating modes.
• Decode — around 20 decoders: analog video (PAL B&W, PAL color scaffold, NTSC), audio (NBFM/WFM/AM/SSB), digital protocols (FT8, WSPR, CW, DMR, LTE MIB, WiFi PHY, LoRa), and an experimental FPV PHY scaffold.

Direction finding

A coherent backend over paired AD9361 SDRs (E310 / LibreSDR / Pluto in any combination) sharing a 10 MHz reference and PPS. Supported algorithms — MUSIC, correlative interferometer, Watson-Watt, and pseudo-doppler. Optionally — a passive bistatic radar scaffold with an FM / DAB+ / DVB-T illuminator catalogue.

Hardened network architecture

Three deployment modes: Isolated (full autonomy), LAN (sync within the local network only), Full (full participation in the federated station mesh). In-house PKI: software-cert station identity with an AES-GCM keyring, operators authenticate via a PBKDF2 vault, certificate revocation — Ed25519-signed CRL with a kill-switch.

Auto-update — cohort-staged signed manifest with 2-attempt rollback. Integration REST API with JWT. Station-to-station mesh — mTLS over length-prefixed frames. Storage — PBKDF2 + AES-GCM software sealer with a TPM probe on Linux.

A separate component — the chain-of-custody session signer: a canonical-JSON session manifest signed with Ed25519. Captures can serve as evidence with a proper audit trail.

Field readiness

Target platform — Ubuntu 26.04 LTS amd64 (.deb package with a systemd unit + a portable AppImage forward-compatible with Ubuntu 24.04). Installs on a typical field laptop, SDR over USB. First minutes after launch — synthetic sources for a smoke test; the hardware is then connected and scanning begins.

How to get access

Beta builds, demos, and full technical documentation — by separate agreement. Reach out via the contact form: we’ll ask for a short brief on the use case, verify the counterparty, and agree NDA terms.
