10. A system comprising:
one or more processors configured to:
receive an output radio frequency (RF) signal;
generate a digitized output RF signal representing the output RF signal;
transmit an output RF waveform associated with the output RF signal;
receive a return RF waveform based on transmission of the output RF waveform;
generate a digitized return RF signal representing a return RF signal associated with the return RF waveform;
serialize the digitized output RF signal and the digitized return RF signal to generate a serialized baseband signal; and
communicate a bit stream based on the serialized baseband signal to an RF unit, wherein the RF unit is configured to generate an altitude measurement, a ground speed measurement, or both for a vehicle based on the serialized baseband signal.
