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

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

    a receive pipeline configured for installation and use on the vehicle, wherein the receive pipeline comprises 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 memory module configured to store interference estimates for each receiver of the plurality of receivers that are estimates of interfering radio signals received by each of the receivers that are transmitted by each respective transmitter of the plurality of transmitters; and

    wherein each receiver of the plurality of receivers is configured to mitigate interference that is due to interfering radio signals transmitted by the plurality of transmitters, as defined by the stored interference estimates of the plurality of transmitters for each particular receiver.
