In these charts I show how to build a synthetic aperture radar (SAR) in your backyard.
There are many reasons to make your own SAR, including:
1. learn about radar imaging by actually doing it yourself
2. SAR image your car to learn why you were pulled over
3. measure the radar cross section of your favorite model airplane
The SAR presented here is based on the $240 rail SAR that i built in graduate school using parts from the Dayton Hamvention, a cordless drill, an old Genie garage door opener, shown here.
Enjoy, and let me know if you build a DIY synthetic aperture radar of your own :)
