Development and Study of a Small Radar

Abstract

In this paper our experience in developing a relatively inexpensive synthetic aperture radar (SAR) for educational purposes is presented. It has also been used as a simple non-imaging Doppler and FMCW radar for the first steps in an educational process with a gradually increasing complexity of the learning content. In SAR mode, the radar moves on a rail in order to ensure accurate rectilinear motion. Synchronizing pulses are produced that allow the processing software to determine the exact radar position. A sample plan for laboratory sessions conducted with this radar is also presented.
