TL;DR
Nawfal Motii has created the AERIS-10, an open-source radar system that brings long-distance scanning capabilities to the maker community at a fraction of the cost of commercial alternatives. Traditional hobbyist radar modules typically have a limited range of only a few meters, but AERIS-10 extends that capability to over 20 kilometers while costing up to 95% less than commercial systems, which can run into the hundreds of thousands of dollars.
