摘要： A method for estimating an occupancy level of a geographic area includes transmitting first signals to and receiving second signals from bodies within the geographic area by backscattering of the first signals. The bodies include first bodies permanently within the geographic area and second bodies temporarily within the geographic area. According to the first and second signals, a first map of the first bodies within the geographic area is generated. At a specified time period, following a reference time period, transmission of the first signals, reception of the radio signals and generation of the first map is repeated. According to the first and second signals, a second map of the bodies within the geographic area is generated. A number of the second bodies within the geographic area during the specified time period is determined as the occupancy level based on comparing the first map to the second map.

摘要： A method for detecting a moving target through a vehicle radar system includes acquiring radar data from a radar sensor disposed with respect to a vehicle, and using the radar data to detect a plane of a structure. The method also includes setting a reference classification line based on the detected plane, and determining whether the moving target is in a line of sight (LOS) area or a non-line of sight (NLOS) area based on the reference classification line.

摘要： A system and method for resolving a first target from a second target by radar is disclosed. The system includes a transmitter for transmitting a source signal, a receiver for receiving first and second echo signals from reflection of the source signal from at least a first target and a second target, respectively. A processor is used to subtract the first echo signal from the composite signal to obtain a second generation of the second echo signal, subtract the second generation of the second echo signal from the composite signal to obtain a second generation of the first echo signal, and estimate a parameter value for the first target from the second generation of the first echo signal and a parameter value for the second target from the second generation of the second echo signal.

摘要： A system and method to sense an environment based on data acquired by side looking radar. For example, a side looking radar is mounted on one or both sides of a ground-based vehicle and performs measurements from environment while the vehicle is moving. As the vehicle moves, a scan of the environment is therefore performed, wherein movement of the vehicle provides another dimension of information for the scan. In another example, the radar can further scan in the vertical plane at a fixed side looking angle to increase the field of view. A 3D map and localization can be determined from the scan.

An edge calculation unit calculates the edges of one or more objects from image data. A marker calculation unit calculates a marker from the capture region. A component region calculation unit calculates component regions by extending the marker using the edges. A grouping unit groups component regions belonging to the same object, of the component regions. The object identification unit identifies the types of one or more objects (e.g., large vehicle, small vehicle, bicycle, pedestrian, flight object, bird) on the basis of a target object region resulting from the grouping.

摘要： A method for classifying vehicles in which an angle-resolving radar device yields measurement signals which have frequencies corresponding to a Doppler shift and which originate from measured vehicles and from which radial distances, object angles and radial velocities can be derived. The frequencies of the acquired measurement signals are stored as functions over the measurement time period, and a spectrogram is formed for every vehicle therefrom. Subsequently, the spectrograms are checked for assessment regions with maximum bandwidth of the frequency. These assessment regions are compared with assessment regions of stored spectrograms for different vehicle classes and associated with the most similar such that the measured vehicles are classified.
