Enhancement of Doppler Unambiguity for Chirp-Sequence Modulated TDM-MIMO Radars [PDF]
2018 IEEE MTT-S International Conference on Microwaves for Intelligent Mobility (ICMIM), 2018 Current automotive radar sensors enhance the angular resolution using a multiple-input multiple-output approach. The often applied time-division multiplexing scheme has the drawback of a reduced unambiguous Doppler velocity proportional to the number of transmitters.
