Practical Examples of Small Synthetic Aperture Radar Imaging Systems

SAR imaging sensors are useful in imaging or mapping a scene from a stand-off range, where the image provided is a bird’s eye view. Small SAR sensors are used for numerous imaging applications including measuring target scattering, imaging through walls of a building, medical imaging, or proving the concept of a much more complicated array-based system without significant investment. Small SAR imaging sensors provide range versus range imagery of near-field target scenes.

The least complex SAR imaging systems can be implemented by placing a small radar sensor onto a linear rail and moved (manually or automatically) along a known path while acquiring range profiles. ...
