1. A method for generating a continuous visualization of vehicle radar scans in a vehicle, comprising:
detecting objects with a beam steered radar scan;
processing data from the beam steered radar scan, wherein the processed data include label information of the detected objects;
generating a Range Doppler Map (“RDM”) corresponding to the processed data;
displaying a visualization of the RDM showing a plurality of the detected objects at a display rate that is higher than a radar scan rate to display continuous movements,
wherein the display rate is updated based on a velocity of the vehicle, and
wherein the visualization overlays images of an environment and is part of an augmented reality system; and
shifting each detected object by its velocity that generates a shifted RDM.
