TSD DOA Engine
Run the benchmarks yourself.
A deterministic direction-of-arrival estimator that approaches the theoretical accuracy floor across array sizes and SNR conditions — independently benchmarked against MUSIC, ESPRIT, and the Cramér-Rao Lower Bound on a public CC0 dataset of 1,518,000 labeled IQ frames. Bit-for-bit reproducible from a fixed master seed.
The TSD DOA engine produces direction-of-arrival estimates that approach the Cramér-Rao Lower Bound across array sizes from N=8 to N=64 elements. There is no threshold tuning, no snapshot-averaging assumption, and no iterative convergence loop. The engine is benchmarked against MUSIC, ESPRIT, and the CRB on a public CC0 dataset of 1.5 million labeled IQ frames — every published number reproduces from a fixed master seed on a clean checkout.
Numbers, with a way to check them.
Every figure below is reproducible against an external comparator. The mechanism is proprietary; the results are not.
What the engine guarantees.
Properties, not mechanism. Outcomes, not implementation.
- Direction-of-arrival accuracy within 0.5% of the Cramér-Rao Lower Bound from N=8 to N=64 elements
- Zero false-alarm rate by architectural design — not a tuned threshold
- Operates on commodity ULA / planar / circular arrays with no hardware modifications
- 1.75 ms end-to-end pipeline latency including detection, DOA, geolocation, and state-machine update
- Bit-for-bit reproducible from a fixed master seed
- Distributed multi-node fusion: 1.4 m geolocation accuracy with four nodes at 0.1° bearing noise
- No transmit, no calibration parameters — fully passive
Run the check yourself.
Public benchmark on Zenodo (CC0): 1,518,000 labeled IQ frames on the Stoica-Nehorai narrowband ULA model. Master seed 20260424. Run MUSIC, ESPRIT, and the TSD DOA engine on identical inputs and compare RMSE, bias, and CRB efficiency directly. No NDA required to reproduce.
All headline numbers on this page reproduce against an independent, industry-standard reference implementation. No NDA required for the verification path.
