Abstract
An apparatus for a low-power radar detection (LPRD) receiver is proposed in this disclosure. The LPRD receiver comprises an analog-to-digital converter (ADC) circuit configured to receive an analog dynamic frequency selection (DFS) signal associated with a DFS channel in a DFS frequency band to generate a digital DFS signal. The ADC circuit comprises a finite impulse response (FIR) filter circuit configured to sample the analog DFS signal at an FIR sampling rate determined based on a predetermined frequency plan associated with the DFS frequency band to generate a sampled DFS signal; and an ADC conversion circuit configured to convert the sampled DFS signal to the digital DFS signal at an ADC conversion rate that is lower than the FIR sampling rate.
