Automotive GMTI radar for object and human avoidance

Automotive radar can be used to detect and identify roadway obstructions including slowly-moving personnel, but must also reduce or remove the effect of platform motion. We measured the capabilities of a 77-GHz system under various conditions, such as rural and urban environments, and on various terrains, such as asphalt and grass. We utilized range Doppler map processing capabilities to correct for platform motion using the variation in the clutter line and identified stationary obstacles as well as vehicles and personnel moving along the path of the system. We tracked pedestrians and vehicles, and detected stationary objects like road boundaries, a fire hydrant, picnic table and utility poles.
