Abstract :
The analysis and implementation of beamforming arrays for three dimensional imaging by a broadband FMCW radar is presented. Measured performance of a non-imaging radar, shows the 3D resolution cell dimensions, commensurate with a practical array, are approximately 5 mm, for a 8-12.6 GHz sweep. Beamforming at the front-end is found superior to post-processing. An implementation of front-end beamforming is included
