- QuadRF is a phased-array radio built with Raspberry Pi 5 and an FPGA, capable of advanced signal processing and beamforming.
- It can detect WiFi through walls and track drones, with open-source potential hinting at more advanced government capabilities.
- QuadRF includes software for RF streaming/decoding, useful for WiFi analysis, and connects via a browser-based VNC interface.
- Developed as part of a Moon-scale antenna project for EME experiments, inspired by SpaceX's Dishy, with modular scalability.
- Testing revealed a functional but rough UI, with an AR visualizer showing RF blobs (4.9-6 GHz) and effective drone detection.
- Uses Raspberry Pi 5's MIPI lanes for high-speed, low-latency SDR I/Q streaming over 5 Gbps, enabling daisy-chaining of modules.
- Crowdfunding success may lead to improved enclosures, though it remains pre-production gear with typical campaign delays.
