Abstract
A radar system comprises a physical radar array comprising a plurality of physical transmit antennas, each configured to transmit a respective signal having a wavelength λ. The physical radar array further comprises a plurality of physical receive antennas, each configured to receive each of the respective signals. The radar system further comprises a neural network configured to receive data from the physical radar array and generate data corresponding to an emulated array of antennas, wherein a defined distance between each antenna of the emulated array of antennas is λ/2.

A radar system comprising:
- a physical radar array comprising:
- a plurality of physical transmit antennas, each configured to transmit a respective signal having a wavelength λ;
- a plurality of physical receive antennas, each configured to receive each of the respective signals;
- and
- a neural network configured to receive data from the physical radar array and generate data corresponding to an emulated array of antennas, wherein a defined distance between each antenna of the emulated array of antennas is λ/2.
A radar system comprising:
- a physical antenna array comprising:
- a plurality of physical transmit antennas, each configured to transmit a respective signal having a wavelength λ;
- a plurality of physical receive antennas, each configured to receive each of the respective signals;
- and
- a processor coupled to the physical antenna array and arranged to:
