Abstract The invention discloses a Loran-C receiver signal processing method based on interpolation FIR (Finite Impulse Response) band-pass filtering and a self-adaptive notch algorithm, which comprises the following steps: firstly, carrying out interpolation band-pass filtering on a signal containing noise to filter out-of-band noise, carrying out spectral analysis on the signal without the out-of-band noise, and then carrying out self-adaptive notch processing to filter out in-band continuous wave interference; a de-noised signal is obtained; or performing spectral analysis on the signal containing the noise, then performing adaptive notch processing to filter out in-band continuous wave interference, and performing interpolation band-pass filtering on the signal after the in-band continuous wave interference is filtered out to filter out-of-band noise to obtain a de-noised signal. According to the method disclosed by the invention, the interpolation FIR band-pass filtering and the self-adaptive notch processing are
