A camera that can see through walls
Applied Electrodynamics built a radar camera that images through walls in 3D using GPUs
“the whole GPU revolution allows you to process them "on the fly" and generate these images”
Applied Electrodynamics is a YC startup using high-frequency radio waves and multi-antenna arrays to image through opaque materials like drywall and marble, producing 1:1 scale 3D models with depth information. The GPU mention is incidental — enabling real-time signal processing rather than AI inference. This is a hardware sensing story with minimal AI industry signal for a conference intelligence newsletter.
