- 4Hacker News·6/30/2026researchBuilt a mmWave Radar for Material Classification
An engineer described building a prototype mmWave FMCW radar to classify materials, with a focus on detecting asbestos-like surfaces. The system used a TI IWRL6432 radar module, ESP32, signal processing, Capon beamforming, and a neural network to generate and classify electromagnetic signatures. The project remained a prototype due to funding constraints.
