Eighteen capabilities that define Varta as a production-grade, field-deployable anti-drone system.
Deploy at the right scale for the mission. All tiers share varta_core for identical classification logic — the same detection engine runs on a compact field unit and a full command center.
v1: Pi Zero 2W + TinySA Ultra+. v2: Pi 5 + HAMGEEK AD9361 (dual RX), ~$243 BOM. Compact field sensor for rapid deployment and personal protection.
Jetson Orin + Fish Ball SDR / PlutoSDR. Full I/Q analysis with 43+ specific signatures, enterprise sensor node or standalone.
Server + Fish Ball SDR / PlutoSDR + Network. Multi-sensor command center with fused confidence scoring, TDOA positioning, tactical display, and fleet coordination.
Matches detected signals against known drone RF fingerprints to identify the platform type. All tiers detect the same drone categories — the difference is classification depth. Mini identifies 10 generic frequency bands (e.g., "2.4 GHz drone activity"). Pro/Max identify 43+ specific platforms (e.g., "DJI Phantom 4, OcuSync, hovering"). No other sub-$100K system carries military FHSS/OFDM signatures.
Multi-stage classification pipeline combining gradient-boosted noise gating, CNN spectrogram analysis, and rule-based heuristics in a HybridDecisionEngine that breaks the 85.9% heuristic false-positive ceiling.
Correlates RF detections with FAA-mandated RemoteID broadcasts and DJI DroneID telemetry to identify compliant vs "dark" (non-broadcasting) drones. Each sensor node acts as a distributed RemoteID receiver, publishing correlation data to Max where it is aggregated in the tactical dashboard.
Identifies when multiple detected drones are operating as a coordinated swarm rather than independent threats. The system analyzes temporal clustering, spatial convergence (within 1 km), behavioral fingerprinting (same RF band and channel spacing), and formation geometry (triangle, line, or cluster patterns). Escalation is automatic: 1 drone = THREAT, 3+ coordinated = EMERGENCY. "Suspected" vs "confirmed" swarm tiers with tracking_id deduplication prevent multi-sensor double-counting.
Five geolocation methods in priority order, automatically selecting the best available based on sensor capabilities and synchronization status. From nanosecond-precision TDOA to always-available RSSI fallback, the system adapts to the deployed sensor mix.
Converts field-captured unknown signals into new detection signatures and pushes them to the entire fleet. On Pro, automatic I/Q capture occurs locally when UNKNOWN, CRITICAL, or EMERGENCY threats are detected. The full review-and-deploy workflow — capture, feature extraction, operator review, approval, and signed fleet push — requires Varta Max. Closes the loop from "unknown signal in the field" to "fleet-wide detection capability" in under an hour.
Every failure mode defaults to the safe state. Invalid data never produces a CLEAR result — the system assumes threat presence until proven otherwise.
Detection events map to STIX 2.1 structured threat intelligence objects for machine-readable sharing with partner systems and government agencies. Satisfies DHS LRBAA RO3 requirement.
Detects RF-silent drones using motor/engine acoustic signatures via USB MEMS microphone with MFCC + spectral feature extraction. Trained on a 13,997-segment corpus with balanced retraining achieving 88.9% overall accuracy. Supplementary modality only — acoustic detection never overrides an RF CLEAR determination.
Correlates detections from multiple geographically distributed sensors to increase confidence and reduce false alarms. Mini and Pro act as Nodes — publishing detections (and DF bearing data from equipped stations) to the network. Max acts as the Hub — aggregating, fusing, and triangulating across all sensors using the 5-method geolocation priority chain. Three transport layers with encryption, edge buffering for disconnected operation, and full provenance tracking on every detection event.
Browser-based operational interface with PMTiles offline mapping, real-time WebSocket threat streaming, and integrated operator tools for the full detection-to-response workflow.
Five independent jammer detection paths ensure no jamming technique evades classification. Each path targets a distinct electronic warfare strategy.
Monitors sensor CPU, temperature, battery, scan rate, noise floor, and clock sync to detect degradation before it causes missed threats or false alarms. On Mini, health monitoring runs locally and triggers local alerts. On Pro, local monitoring plus MQTT health telemetry to the network. On Max, fleet-wide health status is displayed on the dashboard with real-time toast notifications for state changes. Fleet authentication via HMAC-SHA256 ensures only trusted sensors contribute to fusion.
Full lifecycle tracking from discovery through decommission with SensorLifecycleManager managing 25+ state transitions and complete audit history.
Distributes updated signature databases to all sensors with cryptographic verification and rollback protection. Mini and Pro receive OTA updates and verify signatures before applying. Max acts as the Admin — managing releases, hosting a local mirror for air-gapped deployments, and tracking per-sensor registry compliance across the fleet. If a signature update fails verification, the sensor automatically falls back to its last-known-good database.
Deep learning spectrogram classifier trained on 3,804 real-world spectrograms, achieving 90.3% holdout accuracy across 14 drone/jammer classes. Noise false positives reduced from 89.7% to 9.6%. Deployed on Pro via TensorRT INT8 quantization and on Mini v2 via ONNX CPU inference.
End-to-end validation using real RF hardware (PlutoSDR TX → TinySA RX) with realistic channel models. 26 drone/jammer profiles tested through the complete detection pipeline.
