Multi-axis Radar Velocity Image from Stereo Doppler Radar

A system comprising:

• a vehicle;
• a first radar and a second radar coupled at different locations on the vehicle;
• a computing device configured to:
• receive first radar data from the first radar and second radar data from the second radar;
• determine a first radial speed for an object in an environment of the vehicle based on the first radar data and a second radial speed for the object based on the second radar data;
• estimate a velocity vector for the object relative to the vehicle by determining an intersection point based on the first radial speed and the second radial speed;
• provide the estimated velocity vector as an input into a neural network;
• and
• control the vehicle based on an output from the neural network.

A non-transitory computer-readable medium configured to store instructions that, when executed by a computing system, cause the computing system to perform operations comprising:

• receiving first radar data from a first radar and second radar data from a second radar, wherein the first radar and the second radar are coupled at different locations on a vehicle traveling in an environment;
• determining a first radial speed for an object in the environment based on the first radar data and a second radial speed for the object based on the second radar data;
• estimating a velocity vector for the object relative to the vehicle by determining an intersection point based on the first radial speed and the second radial speed;
• providing the estimated velocity vector as an input into a neural network;
• and
• controlling the vehicle based on an output from the neural network.
