Classification: CPC G | IPC G

Claim 13:
14. A radar device associated with a first vehicle, the radar device comprising:
a radar transmitter configured to output a radio frequency (RF) transmission signal including a plurality of frequency-modulated chirps,
a radar receiver configured to:
receive 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,
generate, 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; and

a neural network configured to filter the dataset to reduce the interfering signal included in the dataset, the neural network is a convolutional neural network,
wherein at least one layer of the neural network is a complex-valued neural network layer comprising complex-valued weighting factors selected by the neural network from a predetermined set of discrete values, 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,
wherein the neural network is configured to update the complex-valued weighting factors by selecting updated complex-valued weighting factors from the predetermined set of discrete values.
