Abstract
A method of operating a radar sensor system includes: frequency down-converting a reception signal that is chirp-modulated with a sequence of chirp ramps to an intermediate frequency signal; and high-pass filtering the intermediate frequency signal to produce a high-pass filtered signal. High-pass filtering includes: first high-pass filtering, with a first corner frequency, the intermediate frequency signal at each chirp in the chirp modulation of the reception signal; and replacing the first high-pass filtering with a second high-pass filtering with a second corner frequency, the first corner frequency being higher than the second corner frequency.
