A method for radar imaging is disclosed herein. The method may comprise using a plurality of radar antenna arrays provided on a terrestrial vehicle to obtain phase measurements associated with one or more radar signals transmitted and received by the plurality of radar antenna arrays as the terrestrial vehicle moves through an environment. The method may further comprise processing the phase measurements to compute (i) a set of object-specific properties for one or more objects external to the terrestrial vehicle and (ii) a set of vehicle-specific properties for the terrestrial vehicle. The method may further comprise using the set of object-specific properties and the set of vehicle-specific properties to generate one or more radar images of the environment as the terrestrial vehicle moves through the environment.

Various examples of the present disclosure include a stereoscopic deep neural network (DNN) that produces accurate and reliable results in real-time. Both LIDAR data (supervised training) and photometric error (unsupervised training) may be used to train the DNN in a semi-supervised manner. The stereoscopic DNN may use an exponential linear unit (ELU) activation function to increase processing speeds, as well as a machine learned argmax function that may include a plurality of convolutional layers having trainable parameters to account for context. The stereoscopic DNN may further include layers having an encoder/decoder architecture, where the encoder portion of the layers may include a combination of three-dimensional convolutional layers followed by two-dimensional convolutional layers.

An imaging method and apparatus, a radar system, an electronic device, and a storage medium are provided. A first target image is obtained by obtaining at least two groups of original radar data from different radars, and performing image registration and time-domain coherent superposition. Each group of original radar data corresponds to one radar. The original radar data from the different radars includes different radar information. After image registration and time-domain coherent superposition are performed on the original radar data, the obtained first target image has higher physical resolution. Therefore, resolution of a generated radar image is improved, image information in the radar image is enriched, and positioning accuracy and driving safety of a vehicle are improved.

A method for aiding finding of available parking areas of a street section includes receiving data corresponding to parking areas situated in a street section, the data including information ascertained by an ascertaining vehicle driving through the street section and information received from a server, determining an instantaneous occupancy estimate of the street section based on the received data, calculating a forecasted occupancy estimate based on the instantaneous occupancy estimate using a timer series forecasting model, and generating a display representation of the calculated forecasted occupancy estimate. The method includes receiving the data and determining the occupancy estimate, for example, each time an ascertaining vehicle drives through the street.

A system may include a first sensor of a first type and a second sensor of a second different type and having a detector. A field of view of the second sensor may be formed by a plurality of regions of interest (ROIs) defined by the detector. Control circuitry of the system may be configured to perform operations including obtaining, from the first sensor, first sensor data representing an environment, and determining, based on the first sensor data, information associated with a feature of interest within the environment. The operations may also include determining, based on the information, a particular ROI that corresponds to an expected position of the feature at a later time, obtaining a plurality of ROI sensor data from the particular ROI instead of obtaining full-resolution sensor data, and analyzing the plurality of ROI sensor data to determine one or more attributes of the feature.

Vehicle body panels and systems are described. A vehicle body panel may include at least one layer of material defining the vehicle body panel and one or more than one electronic device, where a portion of each electronic device is embedded within one or more than one of the at least one layer of material. Each electronic device may communicate with a control system or a vehicle control unit of the vehicle to support an advanced-feature functionality of the vehicle. At least one electronic device may include a first portion embedded within the one or more than one of the at least one layer of material. The first portion may be couplable to a second portion, not embedded within the material, where the first portion upon being coupled to the second portion communicates with the control system or the vehicle control unit of the vehicle to support the advanced-feature functionality.

A radar system suitable for use on a vehicle and configured to detect a false radar-track arising from a reflection of a radar return from a target includes a first sensor, a second sensor, and a controller. The first sensor outputs a first signal indicative of a first target in a first area proximate to a vehicle. The second sensor outputs a second signal indicative of a second target in a second area proximate to the vehicle and different from the first area. The controller receives the first signal and the second signal. The controller determines that the second target is a reflection of the first target when a reflection-line that bisects and extends orthogonally from a line-segment extending between the first target and the second target intersects with a reflection surface detected by the second sensor.

In accordance with various embodiments, methods, systems, and vehicles are provided for determining an environment of vehicles. In one embodiment, a vehicle includes a body, a plurality of sensors, and a processor. The plurality of sensors are disposed onboard the vehicle, and is configured to at least facilitate transmitting signals from a vehicle and receiving return signals at the vehicle after the transmitted signals have contacted one or more objects. The processor is disposed onboard the vehicle, and is coupled to the plurality of sensors. The processor is configured to at least facilitate identifying one or more parameters of the return signals; comparing the one or more parameters with historical data stored in a memory; and determining an environment of the vehicle based at least in part on the comparison of the one or more parameters with the historical data.
