Doppler Shift Tolerance of Typical Pseudorandom Binary Sequences in PMCW Radar. [PDF]
Sensors (Basel), 2022 In the context of all-digital radar systems, phase-modulated continuous wave (PMCW) based on pseudorandom binary sequences (PRBSs) appears to be a prominent candidate modulation scheme for applications such as autonomous driving.

Reversal of orbital angular momentum arising from an extreme Doppler shift. [PDF]
Proc Natl Acad Sci U S A, 2018 Significance The emergence of “negative” frequencies in physical systems is often accompanied by intriguing consequences. For example, supersonic motion between a source and an observer leads to a negative Doppler-shifted frequency, the physical meaning ...
