A method of using a multi-input multi-output (MIMO) antenna array for high-resolution radar imaging and wireless communication for advanced driver assistance systems (ADAS) utilizes a MIMO radar and at least one base station. The MIMO radar establishes wireless communication with the base station via an uplink signal. Likewise, the base station sends a downlink signal to the MIMO radar. Further, unlike conventional vehicle-to-everything (V2X) systems that filter the reflected uplink signal, the MIMO radar uses the reflected uplink signal to detect a plurality of targets. Accordingly, the MIMO radar derives spatial positioning data for each target from the reflected uplink signal.
