Claim 17:
18. A method, comprising:
transmitting, by a radar device associated with a first vehicle, a radio frequency (RF) transmission signal including a plurality of frequency-modulated chirps;
receiving, by the radar device, an RF radar signal, wherein the RF radar signal is overlaid with an interfering signal that originates from a radar sensor associated with a second vehicle different from the first vehicle;
generating, by the radar device, based on the RF radar signal, a dataset including a set of digital values, the dataset being associated with a chirp or a sequence of successive chirps of the RF transmission signal and associated with the interfering signal;
selecting, by a convolutional neural network of the radar device, complex-valued weighting factors from a predetermined set of discrete values; and
filtering, by the radar device, the dataset using the convolutional neural network, the convolutional neural network being configured to reduce the interfering signal included in the dataset,
wherein at least one layer of the convolutional neural network is a complex-valued neural network layer comprising the complex-valued weighting factors, wherein the complex-valued neural network layer is configured to perform one or more operations according to a complex-valued computation and the complex-valued weighting factors.
