1. A method for generating a target set using a radar, the method comprising:
generating, using the radar, a plurality of radar images, generating the plurality of radar images comprising
receiving an intermediate frequency signal representative of transmitted and received radar chirps from the radar,
applying first non-uniform discrete Fourier transform coefficients along the intermediate frequency signal for each chirp of the radar chirps in a frame to generate a first set of values, and
applying second non-uniform discrete Fourier transform coefficients along the chirps per range bin of the first set of values to generate the plurality of radar images;
receiving the plurality of radar images with a convolutional encoder; and
generating the target set using a plurality of fully-connected layers based on an output of the convolutional encoder, wherein each target of the target set has associated first and second coordinates.
