    Abstract: Systems and methods are described to identify motion events on a sloped surface, such as a mountainside, using transmitted and received radio frequency (RF) chirps. A one-dimensional array of receive antennas can be digitally beamformed to determine azimuth information of received reflected chirps. Elevation information can be determined based on time-of-flight measurements of received reflected chirps and known distances to locations on the sloped surface. Motion events may be characterized by deviations in return power levels and/or return phase shifts. The systems and methods may, for example, be used to provide real-time detection of avalanches and/or landslides.

    Abstract: A method includes disposing a spherical radar reflector at a location exterior a vehicle equipped with the vehicular sensing system. The vehicular sensing system includes at least two radar sensors disposed at the vehicle and a controller that processes received radio frequency (RF) signals received by the plurality of receivers of each radar sensor of the at least two radar sensors. Calibration RF signals are transmitted by at least one transmitting antenna of a plurality of transmitters of a first radar sensor and a second radar sensor the at least two radar sensors, and reflected first calibration RF signals are received by the plurality of receivers of the first radar sensor and the second radar sensor. Based on a distance between the first radar sensor, the second radar sensor, and the spherical reflector, the vehicular sensing system determines an orientation of the first radar sensor and the second radar sensor.

    Abstract: A radar system, a radar device, and an interference avoidance method are obtained that can utilize frequency effectively even in three or more radar devices. A radar system includes three or more radar devices and a schedule management controller. Schedule management controller predicts an interference time period that is a time period during which the overlapping scanning/radiation range is generated, determines a first interference avoidance measure that is a measure to cause radar devices to use respective different use frequencies while keeping a restriction on the number of frequency channels, in the predicted interference time period, and determines a second interference avoidance measure to be performed by a radar device that is unable to avoid interference by the first interference avoidance measure.

    Abstract: According to one embodiment, a radar receiving system is provided comprising a first receiving circuit, a second receiving circuit, a spectral analyzer, an object detector, and a phase compensation circuit. The spectral analyzer is configured to generate, from a first plurality of reception signals, a first set of Fourier transformation output values and, from a second plurality of reception signals, a second set of Fourier transformation output values. The object detector is configured to determine a range/Doppler bin of a plurality of range/Doppler bins as an estimate of a range and speed of an object. The phase compensation circuit is configured to determine a phase offset between the Fourier transformation output values of the first set and second set of Fourier transformation output values and to compensate the phases of at least a part of the second set of Fourier transformation output values by the determined phase offset.

    Abstract: The present disclosure relates to corner-mounted sensor modules for vehicles containing a multitude of sensor systems based on different types of sensors. In particular, the disclosure relates to a vehicle comprising a first and a second sensor module. The first and a second sensor modules each comprises a rigid structure, one or more first sensors of a first sensor type, one or more second sensors of a second type and an attachment mechanism. A sum of the field of views of the first and second sensor modules is at least 540 degrees. Furthermore, one of the sensor modules is arranged at a front corner of the vehicle 1 and the other sensor module is arranged at a rear corner at the opposite side of the vehicle 1 such that a composed field of view of the two sensor modules covers 360 degrees in relation to a reference point at the vehicle 1.
