System for learning-based processing of radar data

A method comprising:

• receiving, from at least one radar module associated with a vehicle, an incoming radar signal including digitized radar samples indicative of objects in an environment surrounding the vehicle;
• determining a range-Doppler spectrum by processing the incoming radar signal through range and Doppler signal processing;
• determining a set of output predictions for the environment by processing the range-Doppler spectrum through a machine-learning computational model;
• determining a scene representation for the environment based at least in part on the set of output predictions;
• and
• providing the scene representation to an autonomous driving system associated with the vehicle.
