Abstract: In accordance with an embodiment, a method of operating a radar system includes activating a transmitter to transmit a radar signal during a first time period, receiving a reflection of the radar signal from a radar antenna, downconverting the reflected radar signal, and digitally processing the downconverted reflected radar signal within a first frequency bandwidth using a first signal path. The method also includes deactivating the transmitter during a second time period, receiving a second signal from the radar antenna during the second time period, downconverting the second signal, measuring a power of the downconverted second signal within a second frequency bandwidth using a second signal path different from the first signal path, and determining an interference metric based on measuring the power.

Abstract: A method for processing radar data is described herein. In accordance with one embodiment, the method includes the calculation of a Range Map based on a digital radar signal received from a radar receiver. The Range Map includes spectral values for a plurality of discrete frequency values and a plurality of discrete time values, wherein each spectral value is represented by at least a first parameter. Further, the method includes applying an operation to at least the first parameters in the Range Map for at least one discrete frequency value to smooth or analyze at least a portion of the Range Map.
