1. A radar system, comprising:
A radar receiver configured to receive radio signals,
A range Fourier transform stage configured to generate, for each of a plurality of chirps, a vector of range Fourier transform coefficients,
A machine learning model configured to generate, for each of one or more additional chirps, a vector of range Fourier transform coefficients from the vectors of Fourier transform coefficients generated for the plurality of chirps, and
An object detector configured to perform velocity estimation of one or more detected objects using the Fourier transform coefficients generated by the machine learning model.
