QuantNature Global Technical White Paper (Document ID: QN-UARI-2026-V1) Title Universal Acoustic Resonance Imaging (UARI): Super-Resolution Multi-Source Localization and Spatial Energy Condensation across Sub-Wavelength Acoustic Arrays via RPU Physical Continuum Acceleration Author: QuantNature Global (https://www.quantnature.com)Release Date: August 30, 2026Document Version: v1.0 (Digital Twin & HIL Baseline) Executive Summary & Abstract Conventional acoustic phased arrays and industrial sonic cameras constrained by sub-wavelength apertures (D ≤ 71 mm, where D < λ) suffer from substantial diffraction beam broadening (θ ≥ 70°). Consequently, closely spaced acoustic emitters—such as formation-flight UAV swarms in tactical perimeter surveillance or concurrent micro-leakages in pressurized industrial infrastructure—collapse into single, irresolvable energy blobs under linear Delay-and-Sum (DAS) beamforming. This technical white paper formalizes Universal Acoustic Resonance Imaging (UARI), a dual-use computational physics architecture that achieves super-resolution localization by transforming incoming multi-harmonic acoustic phase streams into declarative potential energy landscapes (Vbias) across the 100,000-node physical continuum of the Resonance Processing Unit (RPU). By combining multi-harmonic relative phase coherence with continuous non-linear substrate relaxation, broad point-spread lobes autonomously condense into discrete, localized ground-state limit cycles (Emin), naturally suppressing secondary multi-path room reverberations and background noise. Key Empirical Outcomes (Digital Twin & HIL Benchmarking) Evaluated via a high-fidelity numerical acoustic digital twin coupled with real-time Hardware-in-the-Loop (HIL) open-air Software-Defined Radio (SDR) thermal entropy harvesting under hostile noise conditions (SNR = −8.0 dB): Super-Resolution Multi-Target Separation: Unambiguous discrimination of three simultaneous, closely spaced acoustic sources completely merged under classical linear DAS beamforming. Sub-Grid Spatial Accuracy: Empirical localization precision down to 20.60 mm (≈ 1.2 grid cells on a 1.60 m × 1.60 m evaluation plane at Z = 1.50 m standoff). Dynamic Range & Disparate-SPL Retention: Stable potential basin formation isolating stealth emitters (75 dB) operating alongside high-power heavy propulsion engines (105 dB) without dynamic range masking. Deterministic Real-Time Execution: Verified live execution latency of 127.98 ms per full continuum relaxation on standard GPU hardware (NVIDIA GTX 1070).
