Abstract
In one embodiment, a method includes receiving a portion of a data offload from a radar antenna of a first vehicle. The data offload includes data packets that each include a sequence number and a total number of data packets in the data offload. The method includes generating a data packet log, storing in the data packet log the sequence number of each received data packet, determining that one or more sequence numbers are missing from the data packet log, and sending to the radar antenna, a communication signal that includes an acknowledgement and the sequence numbers that are missing from the data packet log. The method also includes determining that one or more data packets of the data offload include a location of an object in an environment surrounding the first vehicle, and sending the location of the object to a second radar antenna of a second vehicle.
