Abstract
An approach to wireless synchronization between two commercial 77GHz automotive FMCW radar sensors is shown. Our focus is the alignment of a passive listening sensor to a second active transmitting sensor in frequency, time, and waveform modulation parameters, just by observing the signals transmitted from the active sensor. We show that using a combination of inter- and intra-chirpsequence synchronization, the active sensor’s signal can be successfully de-ramped for fast-chirp-sequence waveforms with 275MHz of bandwidth. In addition, we discuss timing requirements and challenges, and characterize the remaining synchronization errors by an analysis of the IF signal data matrix of the de-ramped waveform.
