This is the promise of combining Software-Defined Radio (SDR) with phased array antenna technology. This chapter dives into these fundamental concepts, exploring how a system like the hypothetical &ldquo;QuadRF&rdquo; phased-array radio system would likely be engineered using components like a Raspberry Pi 5 and an FPGA to achieve advanced sensing capabilities.</p>https://ai-blog.noorshomelab.dev/quadrf-phased-array-sdr-2026-07/Sun, 12 Jul 2026 00:00:00 +0000https://ai-blog.noorshomelab.dev/quadrf-phased-array-sdr-2026-07/<p>This section introduces the groundbreaking QuadRF phased-array radio system, detailing its innovative architecture built around the Raspberry Pi 5 and FPGA. Explore its remarkable capabilities, including seeing WiFi signals through walls and precise drone tracking, by understanding the core signal processing and beamforming principles. We also examine the broader implications for open-source development and critical security considerations.</p>
