Abstract

A radar sensing system for a vehicle includes a transmit pipeline, a receive pipeline, and a memory module. The transmit pipeline includes transmitters for transmitting radio signals. The receive pipeline includes receivers for receiving radio signals that include the transmitted radio signals transmitted by the transmitters and reflected from objects in an environment. The memory module is 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. 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.
