Real-time interference mitigation method for automotive radar

A computing device, comprising:

• a memory to store computer-readable instructions thereon;
• and
• at least one processor configured through execution of the computer-readable instructions to:
• receive a return signal using a vehicle radar, the return signal comprising an intended signal and an interference signal;
• transform the return signal to a frequency-time domain return signal using a short-time Fourier transform;
• determine a reconstructed interference signal in the frequency-time domain based on the frequency-time domain return signal, the reconstructed interference signal comprising an estimation of the interference signal;
• transform the reconstructed interference signal to a time domain version of the reconstructed interference signal;
• and
• remove the interference signal in the time domain from the return signal to isolate the intended signal in the time domain based on the time domain version of the reconstructed interference signal.

A system, comprising:

• a vehicle radar coupled to a computing device,
• wherein the computing device is configured to:
