Abstract: Methods and apparatus to implement compact time-frequency division multiplexing for MIMO radar are disclosed. An apparatus includes an antenna array controller to: transmit a first signal via a first transmitter of a radar antenna array, the first signal having a first duration and modulated across a first frequency range; and transmit a second signal via a second transmitter, the second signal having a second duration and modulated across a second frequency range, the first and second durations including an overlapping period of time, the first and second frequency ranges including an overlapping frequency range. The apparatus further includes a signal separation analyzer to: determine a first echo received at a receiver of the radar antenna array corresponds to the first signal; and determine a second echo received at the receiver corresponds to the second signal.
