Abstract :
An RF Multibeam Spatio-Temporal RAKE radar architecture uses multi-beam beamforming and waveform diversity to isolate line-of-sight and multipath reflections for enhanced imaging. A 90 nm CMOS, 4-channel, 4-beam, 24-to-26 GHz vehicular radar prototype integrates a 4-channel mm-Wave front-end, a 4×4 multibeam matrix, and 4 high-speed mixed-signal baseband processors.
