Systems, devices, and methods for real-time inteference detection

A method for processing a digitized radar signal, the method comprising:

• obtaining a radar signal;
• wherein for one or more iterations, the method comprises:
• determining a first power of at least one first signal sample of the radar signal;
• determining a second power of at least one second signal sample of the radar signal, the at least one second signal sample being subsequent in time to the at least one first signal sample;
• and
• determining a difference value between the second power and the first power;
• and
• wherein the method further comprises detecting a burst interference signal occurrence within the radar signal based on the difference values from the one or more iterations.

A device comprising:

• an interference detector comprising signal processing circuitry that comprises:
• one or more processors configured, for one or more iterations, to:
• determine a first power of at least one first signal sample of a radar signal, the at least one first signal sample of the radar signal being within a first processing window of the radar signal, the first processing window comprising one or more samples or the radar signal;
• determine a second power of at least one second signal sample of the radar signal, the at least one second signal sample being within a second processing window of the radar signal, the second processing window comprising one or more samples of the radar signal with at least one of the one or more signal samples of the second window being subsequent in time to signal samples of the first processing window
• determine a difference value between the second power and the first power;
• wherein the one or more processors are further configured to detect a burst interference signal occurrence within the radar signal using the difference values from the one or more iterations, and wherein the device further comprises:
• a sample synthesizer configured to synthesize, from the radar signal, one or more synthesized samples;
• and
• a combine and replace circuit configured to, in response to the interference detector detecting the burst interference signal occurrence within the radar signal, replace the one or more interfered samples with respective synthesized samples to produce a modified radar signal.
