1. A multiple input, multiple output (MIMO) radar system, the MIMO radar system comprising:
a plurality of transmitters configured to transmit radio signals;
a plurality of receivers configured to receive radio signals that include radio signals transmitted by the transmitters and reflected off objects in an environment, wherein the received radio signals also include interfering radio signals transmitted by other radar systems, wherein the plurality of receivers is configured to measure the received radio signals for interference during selected time periods when the plurality of transmitters is not transmitting, and wherein the plurality of receivers is configured to receive the received radio signals while the plurality of transmitters is transmitting and while the plurality of transmitters is not transmitting;
an interference manager configured to control the plurality of transmitters and the plurality of receivers to avoid and/or mitigate interference from the other radar systems, wherein the interference manager is configured to analyze the received radio signal measurements to detect interfering radio signals, wherein the interference manager is operable to select a time slot, frequency band, or a time slot/frequency band for transmitter/receiver operation to avoid the interference, wherein the interference is detected interference, and wherein the plurality of receivers is configured to process the received radio signals to detect at least one object in the environment.
