1. A system comprising:
a radar antenna array;
a hardware logic component; and
a computing device, wherein the hardware logic component and the computing device are configured to collectively perform acts comprising:
responsive to receipt of radar data that is indicative of a radar return received by the radar antenna array from a field of view (FOV) of the radar antenna array, encoding the radar data into a first embedding, wherein encoding the radar data into the first embedding comprises providing the radar data to a first neural network configured to map input to a first latent space, and wherein the first embedding is output by the first neural network and is a mapping of the radar data in the first latent space;
transforming the first embedding to a second embedding by providing the first embedding as input to a second neural network, wherein the second embedding is included in output of the second neural network, wherein the second embedding is representative of beamformed radar data in a second latent space, and wherein the second neural network is configured to map input from the first latent space to the second latent space; and
decoding the second embedding to generate the beamformed radar data, wherein the beamformed radar data is indicative of a partial radar return received by the radar antenna array from a subset of the FOV of the radar antenna array.
