Abstract: The disclosure relates to a method for operating a sensor circuit in a motor vehicle, wherein a processor in the sensor circuit receives a reflection signal from an environment of the motor vehicle by way of an environmental sensor and ascertains from the reflection signal a particular detection point, which describes a relative position of a reflection event with respect to the motor vehicle. The disclosure involves the processor using pattern data to establish a surface region in the environment and a category of the surface region and checking for the detection point whether it lies in the surface region, and the detection point which lies in a surface region is categorized according to the pattern data of the surface region and the detection point is filtered according to its categorization by way of a filtering action for trajectory planning of a driving trajectory of the motor vehicle.

Abstract: A method and processor to determine spatial information regarding a vehicle. The method includes receiving at least one initial frame of FMCW radar data including spatial information regarding the vehicle associated with a radar signal reflected back from the vehicle via a surface of at least one stationary object other than the vehicle. The method also includes receiving at least one further frame of FMCW radar data including: spatial information regarding the vehicle associated with a radar signal reflected back from the vehicle via the surface of at least one stationary object other than the vehicle, and spatial information regarding the vehicle associated with a radar signal reflected directly back from the vehicle. The method further includes using the at least one initial frame of radar data to correct for static clutter associated with the at least one stationary object in the at least one further frame of radar data.

Abstract: A method and apparatus for acquiring chirp data in a frequency modulated continuous wave (FMCW) radar system of a road vehicle. The method includes transmitting a FMCW signal comprising a plurality of ramping regions in which a frequency of the FMCW signal ramps up to a first frequency or ramps down to a second frequency. The method also includes receiving a reflected signal corresponding to the reflection of the FMCW signal from one or more physical objects. The reflected signal includes a plurality of ramping regions corresponding to the ramping regions of the transmitted FMCW signal. The method further includes sampling the reflected signal by: taking a plurality of samples in a ramping region in which the frequency of the reflected signal ramps up; and taking a plurality of samples in a ramping region in which the frequency of the reflected signal ramps down.

Abstract: A system and method to classify objects using radar data obtained by an automotive radar. The system includes a convolutional network having a plurality of hidden layers comprising convolution layers for extracting features from the radar data, and an output. The system also includes a deconvolutional network having a plurality of hidden layers comprising deconvolution layers for classifying the features extracted from the radar data, and a classification output. The system also includes a filter having an input coupled to the classification output of the deconvolutional network. The system further includes a fully connected network having a plurality of fully connected layers for determining a clutter threshold value from the output of the convolutional network. The filter is operable to use the clutter threshold value to filter noise and/or clutter from the classification output of the deconvolutional network and pass a filtered classification output to an output of the system.
