The \"Coffee-Can\" Radar Redesigned as an Inexpensive RF PCB [Application Notes]

This article describes an inexpensive and small-size radar RF core that can be integrated into applications such as drones and unmanned vehicles and opens the door to many projects requiring better environmental sensing. Our work was inspired by the November 2012 IEEE Spectrum article "Coffee-Can Radar: How to Build a Synthetic Aperture Imaging System with Tin Cans and AA Batteries" [1], which describes a simple radar system that can be built with easily obtainable RF components.
