Poster: Thermal Compensation in RF Measurement Electronics Attestation Systems

RF signatures are highly sensitive to temperature. Even small variations introduce non-linear distortions that reduce the reliability of attestation methods in production environments.

​​Award Winning Poster

Presented at APEX Expo 2026, this work introduces a simple, data-driven compensation approach that models temperature-induced signal variation and normalizes measurements back to a baseline condition. By applying polynomial regression to real measurement data, the method enables consistent comparison across changing thermal conditions.

The results, conducted across a controlled temperature range, show clear alignment between raw and compensated signals, validating the approach.

Why this Matters for RF Measurement

This award-winning APEX 2026 poster presents a practical method to remove that noise:

• Makes RF-based attestation viable in real manufacturing environments

• Reduces false positives and missed defects caused by thermal variation

• Strengthens detection of counterfeits, defects, and tampering at scale

This poster offers a practical step toward deploying physics-based, black-box verification methods in production, not just controlled lab settings.
