Systems and methods for estimating vehicle speed based on radar

Abstract:

Systems, methods, and non-transitory computer-readable media can receive a frame of data generated by a radar system on a vehicle that is associated with an environment at a particular time as detected by the radar system. The frame of data can comprise a plurality of angular positions. Data points included within the frame of data that correspond to the plurality of angular positions can be determined. A fit of a curve having a trigonometric function can be determined to the data points. A speed estimate for the vehicle can be generated based at least in part on the fit of the curve to the data points.
