1. A method comprising:
quantizing points of a RADAR data packet according to a target resolution;
determining coordinate deltas between quantized points included in one or more respective tiles of a plurality of tiles of the RADAR data packet to obtain one or more respective tile delta sets; and
applying compression encoding to the one or more respective tile delta sets using one or more pre-computed encoding trees to obtain a compressed RADAR data packet.
 
8. A processor comprising:
one or more circuits to:
determine coordinate deltas with respect to points of a RADAR data packet to obtain one or more delta sets; and
apply compression encoding to the one or more respective delta sets using one or more pre-computed encoding trees to obtain a compressed RADAR data packet.
 
16. A system comprising:
one or more processing units to:
quantize points of a RADAR data packet according to a target resolution that is based on a localization tolerance of autonomous driving operations;
determine coordinate deltas with respect to the quantized points to obtain one or more delta sets; and
apply compression encoding to the one or more respective delta sets using one or more pre-computed encoding trees to obtain a compressed RADAR data packet.
