A proprietary direction-of-arrival algorithm that outperforms published industry-standard methods by 39–92% in bearing accuracy, operates from as few as 5 data snapshots with no fallback, and achieves zero false detections across 10,000 noise trials. Fully benchmarked, publicly verifiable, and ready for integration into existing passive RF systems.
The TSD DOA engine is a proprietary passive RF bearing estimation algorithm benchmarked head-to-head against MUSIC and ESPRIT on 1,518,000 labeled IQ frames using the Stoica-Nehorai narrowband ULA signal model — the field standard for phased array validation.
Key validated results:
The benchmark dataset — TSD-DOA-Benchmark-v1 — is publicly released on Zenodo under CC0, master seed 20260424. All results are bit-for-bit reproducible by any third party.
The DOA engine is one module of a broader compiled passive RF intelligence system. Additional validated capabilities exist and are available for discussion under NDA.

Desired business relationship
Other : Defense contractor partners or program offices interested in evaluating a passive RF DOA capability that materially outperforms published methods. Live demonstration available against customer-provided or synthetic scenarios. NDA required for full system discussion.
Other : Technology licensing, research and development partnerships, and hardware validation collaborations.
New Leaf Tools LLC is a solo-founded technology company built on a proprietary mathematical framework that is domain-agnostic by design. The same core engine powers multiple independent technology products across different industries — each one solving problems that existing methods have been unable to solve.
Current technologies include a passive RF intelligence system for defense applications — covering direction-of-arrival estimation, adaptive beamforming, emitter tracking, and cognitive EW — and a Selective Harmonic Elimination solver for power electronics that finds every solution in the complete solution space, a capability the field has considered intractable for four decades.
The common thread is a deterministic mathematical engine that replaces statistical approximation and iterative search with exact, certified answers. No training data. No threshold tuning. No heuristics. Just math.
New Leaf Tools LLC is actively seeking defense contractor partners, licensing discussions, and research collaborations. All technology is delivered as compiled binaries with no source exposure required.
