1. A radar sensing system comprising:
a plurality of transmitters configured to transmit radio signals; and
a plurality of receivers configured to receive radio signals that include the transmitted radio signals transmitted by the transmitters and reflected from objects in an environment;
a code generator configured to generate first and second spreading code chip sequences, wherein the code generator comprises a plurality of shift registers configured to produce the code chip sequences;
wherein first and second transmitters of the plurality of transmitters are configured to generate radio signals defined by the first and second spreading code chip sequences, respectively; and
wherein a first receiver of the plurality of receivers is configured to process received radio signals as defined by a plurality of spreading code chip sequences that comprises at least the first and second spreading code chip sequences.
