Abstract: The present disclosure provides a systems and methods for processing radar data. In one example embodiment, a first digitized radar signal of an environment is received from a first radar module and a second digitized radar signal of the environment is received from a second radar module. The first digitized radar signal and the second digitized radar signal are processed, via an electronic processor, to determine a set of correction parameters. A first corrected radar signal is determined by applying the set of correction parameters to the first digitized radar signal. A second corrected radar signal is determined by applying the set of correction parameters to the second digitized radar signal. The first and second corrected radar signals are combined into a combined radar signal. A scene representation of the environment is determined based on the combined radar signal. The scene representation is provided to an autonomous driving system.

Abstract: A computing device for a radar sensor for identifying a disruption of the radar sensor through blocking or interference includes at least one interface for receiving radar data from the radar sensor and at least one processing device configured to determine at least one characteristic figure for a range of values in a noise distribution in the radar data, in which at most few and/at most weakly reflecting objects are present, and evaluate the characteristic figure in order to identify a disruption of the radar sensor.

Abstract: The invention relates to a method for interference suppression, wherein: a. a time signal (10) is provided, b. an interference range (16) of the time signal (10) is determined, c. a modified time signal (18) is provided by suppressing the interference range (16) of the time signal (18), d. a spectrum (20) of the modified time signal (18) is determined and a suppression spectrum (28) of the suppressed interference range (16) is determined, e. a real frequency component (30) of the spectrum (20) is determined, f. a modified suppression spectrum (34) is determined from a characteristic variable of the real frequency component (30) of the suppression spectrum (28), g. the modified suppression spectrum (34) is subtracted from the spectrum (20) to provide a corrected spectrum (36). The invention also relates to two methods for signal restoration on the basis of the method for interference suppression.
