1. A radar sensing system for a vehicle, the radar sensing system comprising:

  • a plurality of transmitters configured for installation and use on a vehicle, and configured to transmit radio signals;

    a plurality of receivers configured for installation and use on the vehicle, and configured to receive radio signals that include the transmitted radio signals transmitted by the transmitters and reflected from objects in an environment; and

    a programmable code generation unit configured to provide sequences of spreading code chips to digital signal generators of the transmitters and to digital baseband processing sections of the receivers;

    wherein one sequence of spreading code chips is provided to each transmitter while multiple sequences of spreading code chips are provided to each receiver;

    wherein a sequence of spreading code chips is used by a digital signal generator of a first transmitter of the plurality of transmitters to generate transmitted radio signals; and

    wherein multiple sequences of spreading code chips are used by a digital baseband processing section of a first receiver of the plurality of receivers to process received radio signals.
