1. A method, comprising:
receiving a radar signal of an object in motion;
converting the radar signal into an input vector, the input vector including time and frequency information of the object in motion;
providing the input vector as input to a neural network, where the neural network has access to a set of initial data that has been generated based on a plurality of initial radar signals of a plurality of initial objects in motion; and
determining a spin rate of the object in motion based on an analysis performed by the neural network of the input vector including time and frequency information of the object in motion in view of the set of initial data, the analysis including comparing a first set of harmonics of the input vector to a second set of harmonics of a time-frequency image in the set of initial data.
