Abstract
A radar apparatus and an interference suppression method are provided. The radar apparatus includes a clock generator, an analog to digital converter (ADC), and a notch filter. The clock generator is configured to generate a sampling frequency. The ADC is coupled to the clock generator, and is configured to convert an analog signal into a digital signal according to the sampling frequency. The notch filter is coupled to the ADC, and is configured to attenuate one or more interfered frequencies of the digital signal. The interfered frequencies are related to the sampling frequency. Accordingly, the interference at a specific frequency and harmonics thereof may be suppressed.
