Developer Constructs Millimeter‑Wave Radar for Material Classification

The author announces the creation of a millimeter‑wave radar system. The device is designed to classify different materials based on their reflected signals. It operates in the mmWave frequency band, offering high resolution. The post details the hardware components used in the build. It explains the signal‑processing techniques employed to differentiate materials. Test results show distinct signatures for common substances. The author shares schematics and software code for replication. The project invites further experimentation and potential applications in sensing.
