Abstract
A radar signal processor includes a baseband signal generator, which generates a baseband signal based on information from a received radar signal and a Lead-Lag filter, which filters the baseband signal to generate a filtered signal.
Claims18
A radar signal device, comprising:
- a baseband signal generator, which generates a baseband signal based on an information from a received radar signal;
- and
- a Lead-Lag filter, which filters the baseband signal to generate a filtered signal.
A method, comprising:
- receiving a baseband signal having information on a distance of an object;
- filtering the baseband signal using a Lead-Lag-filter to generate a filtered signal;
- and
- determining whether safe operation conditions of a radar system exist based on whether a signal property of a DC component of the filtered signal fulfills a predetermined condition.
