Claim 11:
12. A device comprising:
an interference detector comprising signal processing circuitry that comprises:
one or more processors configured to:
determine a first power of a first signal sample of a radar signal;
determine a second power of a second signal sample of the radar signal, the second signal sample being subsequent in time to the first signal sample;
determine a first difference value between the second power and the first power;
determine a third power of a third signal sample of the radar signal, the third signal sample being subsequent in time to the first signal sample, the second signal sample being subsequent in time to the third signal sample;
determine a fourth power of a fourth signal sample of the radar signal, the fourth signal sample being subsequent in time to the third signal sample and the second signal sample;
determine a second difference value between the fourth power and the third power;
determine whether the first difference value exceeds a first non-zero threshold;
determine whether the second difference value exceeds the first non-zero threshold;
determine a quantity indicating how many of the first difference value and the second difference value exceed the first non-zero threshold;
determine whether the quantity exceeds a second non-zero threshold; and
detect a burst interference signal occurrence within the radar signal based on whether the quantity exceeds the second non-zero threshold;

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.
