An apparatus comprising: transmission circuitry to transmit time division multiplexing multi-input multi-output (MIMO) radar signals by transmitting sets of successive radar signals, each set having a pulse repetition interval that is different than respective PRIs of sets of radar signals transmitted in another one of the sets; receiver circuitry to receive ones of the radar signals reflected from a target; and processing circuitry to ascertain positional characteristics of the target based on the PRI used in each of the sets and on phase characteristics of the ones of the radar signals reflected from the target and received via the receiver circuitry; wherein the transmission circuitry includes a plurality of transmitters, each transmitter to transmit one of the sets of successive radar signals using a PRI that is different than a PRI used by other ones of the transmitters; wherein the processing circuitry is to apply phase compensation to the reflected signals by resolving radial velocity of the respective signals, including selecting peaks of the reflected signals that overlap one another, wherein peaks are samples above a detection threshold and with magnitude higher than its two adjacent neighbors; wherein selecting the peaks of the reflected signals includes selecting peaks having a position and magnitude that overlaps peaks in unwrapped spectrums of other ones of the reflected signals illuminated by other transmitters; wherein the processing circuitry is to apply phase compensation to the reflected signals by unwrapping spectrum samples from the reflected signals and forming an extended ±inter-2π spectrum, and by identifying aligned peaks in the unwrapped spectrum samples. transmission circuitry to transmit time division multiplexing multi-input multi-output (MIMO) radar signals by transmitting sets of successive radar signals, each set having a pulse repetition interval that is different than respective PRIs of sets of radar signals transmitted in another one of the sets; receiver circuitry to receive ones of the radar signals reflected from a target; and processing circuitry to ascertain positional characteristics of the target based on the PRI used in each of the sets and on phase characteristics of the ones of the radar signals reflected from the target and received via the receiver circuitry; wherein the transmission circuitry includes a plurality of transmitters, each transmitter to transmit one of the sets of successive radar signals using a PRI that is different than a PRI used by other ones of the transmitters; wherein the processing circuitry is to apply phase compensation to the reflected signals by resolving radial velocity of the respective signals, including selecting peaks of the reflected signals that overlap one another, wherein peaks are samples above a detection threshold and with magnitude higher than its two adjacent neighbors; wherein selecting the peaks of the reflected signals includes selecting peaks having a position and magnitude that overlaps peaks in unwrapped spectrums of other ones of the reflected signals illuminated by other transmitters; wherein the processing circuitry is to apply phase compensation to the reflected signals by unwrapping spectrum samples from the reflected signals and forming an extended ±inter-2π spectrum, and by identifying aligned peaks in the unwrapped spectrum samples.
