METHOD, DEVICE, AND SYSTEM FOR INTERFERENCE REDUCTION IN A FREQUENCY-MODULATED CONTINUOUS-WAVE RADAR UNIT

There is provided a method for interference reduction in a stationary radar unit of a frequency-modulated continuous-wave, FMCW, type. A sequence of beat signals is received, and a reference beat signal is calculated as an average or a median of one or more of the beat signals in the sequence. By co...

More Information
Summary:There is provided a method for interference reduction in a stationary radar unit of a frequency-modulated continuous-wave, FMCW, type. A sequence of beat signals is received, and a reference beat signal is calculated as an average or a median of one or more of the beat signals in the sequence. By comparing a difference between a beat signal and the reference beat signal, or a derivative of the difference, to one or more thresholds, a segment which is subject to interference is identified. The segment of the beat signal is replaced by one or more of a corresponding segment of an adjacent beat signal in the sequence, and a corresponding segment of the reference beat signal.
