Continuous visualization of beam steering vehicle radar scans
Examples disclosed herein relate to generating continuous visualizations of beam steering vehicle radar scans by acquiring data for a beam steering radar scan, generating a Range Doppler Map (“RDM”) corresponding to the acquired radar data, displaying a visualization of the RDM showing a plurality of identified objects, shifting each identified object by its velocity to generate a shifted RDM, and updating the visualization at a display rate that is higher than a radar scan rate to display continuous movement. The display may be part of an augmented reality system presented to a driver on a windshield or dashboard.
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;

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.
2. The method of claim 1 , further comprising:
overlaying the visualization over a windshield.
3. The method of claim 1 , wherein the augmented reality system comprises an augmented reality dashboard display.
4. The method of claim 1 , wherein the augmented reality system comprises a heads up display that displays information on a windshield of the vehicle.
5. The method of claim 1 , wherein the beam steered radar scan is performed over a plurality of field of views and at a plurality of angles.
6. A system for use in a vehicle, comprising:
a radar module configured to detect objects in an environment of the vehicle;
a perception module configured to generate label data for the detected objects;
a display module configured to present an augmented reality display; and
a pseudo visual module configured to receive return radar signals from the radar module identifying the detected objects, the pseudo visual module further configured to apply a velocity of the detected objects and determine display positions on the augmented reality display,
wherein the pseudo visual module is further configured to generate a continuous visualization of locations and movements of the detected objects at a display rate based on the velocity of the detected objects,
wherein the display rate is updated based on a velocity of the vehicle, and
wherein the display module is further configured to display the locations and the movements of the detected objects as part of the augmented reality display of the environment of the vehicle.
7. The system as in claim 6 , wherein the radar module is further configured to perform beam steering radar scans over a plurality of field of views and at a plurality of angles.
8. The system as in claim 7 , wherein the radar scan has a scan rate and a scan angle.
9. The system as in claim 8 , wherein the display module has a display rate that is greater than the scan rate of the radar scan.
10. The system as in claim 6 , wherein the display module is a part of an augmented reality dashboard display.
11. The system as in claim 6 , wherein the display module is a part of a heads up display that displays information on a windshield of the vehicle.
12. A radar display system for a vehicle, comprising:
an antenna module configured to transmit and receive radar signals;
a Range Doppler Map (“RDM”) module configured to determine a range and a velocity of an object detected in the received radar signals;
a prediction module adapted to label the detected object;
a processing module configured to determine a location of the detected object as a function of a velocity of the detected object; and
a display module configured to display the location of the detected object at a display rate based on a velocity of the vehicle.
13. The radar display system as in claim 12 , wherein the display module is part of an augmented reality system.
14. The radar display system as in claim 12 , wherein the radar signals have a scan rate across a field of view.
15. The radar display system as in claim 12 , wherein the display module has a display rate that is greater than a scan rate of the radar signals.
16. The radar display system as in claim 12 , wherein the display module is further configured to display a plurality of objects, and identify each type of object from the plurality of objects.
17. The radar display system as in claim 12 , wherein the display module is a part of an augmented reality dashboard display.
18. The radar display system as in claim 12 , wherein the display module is a part of a heads up display that displays information on a windshield of the vehicle.
