Abstract: Aspects of the present disclosure are directed to radar communications with disparate pulse repetition intervals, as may be implemented with radar transmission, receiver and processing circuitry. As may be utilized in accordance with one or more embodiments herein, time division multiplexing (TDM) multi-input multi-output (MIMO) radar signals are transmitted by transmitting sets of successive radar signals, each set having a pulse repetition interval (PRI) that is different than the PRI of sets of radar signals transmitted in another one of the sets. Positional characteristics of a target may be ascertained based on the PRI used in each of the sets and on phase characteristics of ones of the radar signals reflected from the target.

Abstract: Aspects of the present disclosure are directed toward apparatuses and/or methods involving the communication of radar signals. Certain aspects involve communicating time division multiplexing (TDM) multi-input multi-output (MIMO) radar signals, having pulses with a chirp interval time (CIT) that is different for respective chirps. Positional characteristics of a target may be ascertained based upon both the CIT between each chirp in the communicated radar signals and the time between each corresponding chirp in received ones of the signals reflected by the target. Communication of the radar signals may involve utilizing a combination of antennas to provide a virtual aperture.
