Contraband Shadow — Concealed Metal Anomaly Imaging

Inside a metal vehicle, a small hidden metal object vanishes into the glare — physics says no.

Readiness Physics limit

Retained for transparency, but blocked from execution because the catalog physics review rejected it.

Evidence Unvalidated concept

An early research proposal with no capability-specific product validation yet.

Runtime family Not mapped

No browser runtime is assigned to this capability yet.

Why live sensing is unavailable

The vehicle is itself a large metal enclosure dominating scattering; a small added metal object's contribution against that metal-cabin background, amid seat/occupant reconfiguration, is below practical detectability. Differencing is valid in principle but defeated by the background.

Intended capability

Evaluate the sensing evidence for “Contraband Shadow — Concealed Metal Anomaly Imaging” in a stationary, controlled, ground-truthed vehicle study. This is not a vehicle, occupant, child, pet, or driver-safety system.

This describes the intended outcome. Readiness is physics limit, evidence is class C, and a catalog mapping or recording is not proof of this outcome at a real site.

Bundled recording

A related Automotive scene

This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.

01 The physics

Metal is a near-perfect scatterer: a new metallic object creates strong specular paths (new CIR taps) and a high-sigma region in the reconstructed conductivity field. A vehicle's own metal structure is static, so any new persistent high-sigma voxel that isn't in the baseline map is anomalous by construction.

02 Shared processing path

CIR sparse recovery for new specular taps -> RFF/NeRF sigma-field reconstruction -> voxel differencing vs vehicle's own baseline sigma map -> MVE anomaly scoring with location output.

This is a capability design path. Components may be shared with other catalog entries; it is not presented as a unique algorithm.

03 Validation plan

Own-hardware: van cabin and luggage rack, insert metal plates/toolboxes 0.5-5kg at varied positions and concealments, ROC of sigma-anomaly score vs mass and depth; ESP32-wall dataset for through-panel propagation priors.

04 Commercial hypothesis

Passive metallic-anomaly screening for fleet vehicles and transit cars — no millimeter-wave portal, no imaging of people — sold to transit police tech units and armored/high-value logistics security chiefs.
