Various technologies described herein pertain to disambiguating velocity estimate data of a radar sensor system. First range estimate data can be computed based on samples from a period of a ramp for each ramp in a sequence. First velocity estimate data can be computed based on samples from a range bin across the ramps in the sequence for each range bin. For each of the ramps in the sequence, samples from a period of a ramp can be divided into a plurality of groups of the samples respectively from periods of subramps. The first velocity estimate data can be disambiguated to generate second velocity estimate data. The first velocity estimate data can be disambiguated based on the plurality of groups of the samples respectively from the periods of the subramps.

Velocity disambiguation for radar sensor system

Various technologies described herein pertain to a radar sensor system that performs ego motion estimation. A radar sensor system can be utilized to generate an instantaneous three-dimensional ego motion estimate of a vehicle. The radar sensor system employs an algorithm that enables generating ego motion estimates for velocities of the vehicle that can be greater than, less then, or equal to the unambiguous maximum velocity of the radar sensor system. Moreover, a single radar sensor system of a vehicle can implement the approaches set forth herein and the techniques can be applicable regardless of modulation of the radar sensor system.
