Spatiotemporal Encoding With Nonlinear Gradient Hardware Using Pulseq: From Principles to Practical Demonstration. [PDF]
Magn Reson MedPurpose Provide the theoretical foundation and the first practical demonstration of spatiotemporal encoding (SPEN) using additional nonlinear gradient hardware. Methods The quadratic phase profile can be generated either by a chirped‐RF pulse combined with a constant gradient or, directly, by a quadratic gradient pulse.

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.
