mr_radar is an in development open hardware frequency modulated continuous wave radar.
It is a radar altimeter for remote control quad-rotor helicopters and UAVs. Eventually, it may be capable of radar imaging. One of the goals of this project is to be easily reproducible and inexpensive.
Board layout is done so using KiCad. Measurements (s-parameters, noise figure measurements) are available in data/

Questions
How big is the Radar PCB?
It measures 70 × 43.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Radar use?
87 parts, built around the OPA1664AIPW. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Radar KiCad files?
From the loxodes/mr_radar repository on GitHub, at the commit this page was made from: the board is hardware/radar.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Radar design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
