Abstract
Example embodiments described herein involve techniques for orthogonal Doppler coding for a radar system. An example method may involve causing, by a computing system coupled to a vehicle, a radar unit to transmit a plurality of radar signals into an environment of the vehicle using a two-dimensional (2D) transmission antenna array, wherein the radar unit is configured to use time division multiple access (TDMA) to isolate transmit channels along a horizontal direction of the 2D transmission antenna array and Doppler coding to isolate transmit channels along a vertical direction of the 2D transmission antenna array. The method may further involve receiving, by the computing system and from the radar unit, radar reflections corresponding to the plurality of radar signals, determining information representative of the environment based on the radar reflections, and providing control instructions to the vehicle based on the information representative of the environment.
