This document describes techniques for using occlusion constraints for resolving tracks from multiple types of sensors. In aspects, an occlusion constraint is applied to an association between a radar track and vision track to indicate a probability of occlusion. In other aspects, described are techniques for a vehicle to refrain from evaluating occluded radar tracks and vision tracks collected by a perception system. The probability of occlusion is utilized for deemphasizing pairs of radar tracks and vision tracks with a high likelihood of occlusion and therefore, not useful for tracking. The disclosed techniques may provide improved perception data more closely representing multiple complex data sets for a vehicle for preventing a collision with an occluded object as the vehicle operates in an environment.

A method and an apparatus for recognizing an absorptive radome coating on an apparatus for emitting electromagnetic radiation and receiving partial radiation reflected at objects is disclosed. The radome covers at least one antenna of the apparatus. A mixer mixes a frequency-modulated transmission signal with the signal received by the at least one antenna, the mixed product of the mixer is subjected to analog-to-digital conversion, the digitized signal is transformed into a two-dimensional spectrum, and the two-dimensional spectrum is mapped with a transfer function. The two-dimensional spectrum that was mapped with the transfer function is correlated with correlation matrices in order to carry out pattern recognition.

Systems and methods are described for monitoring detection of objects in a sensor. The system can generate an occupancy array based on scene data corresponding to a scene of a vehicle. The array can include points that represent a location within the environment of the vehicle and an occupancy value that indicates whether an object is detected at that location. The system can modify an occupancy value of at least one point in the array and identify at least one static object miss based on a group of occupancy values of a group of points in the array.

Methods and devices for estimating a component transmission loss are provided. In an exemplary embodiment, a method includes receiving a desired substrate criterion of a desired substrate, and receiving a desired coating criterion of a desired coating. A component includes the desired substrate and the desired coating. A coating criterion value is received, where the coating criterion value quantifies the desired coating criterion. A desired coating permittivity is estimated for the desired coating, using the coating criterion value, and an estimated component transmission loss of radar signal through the component is produced.

Systems and methods for controlling an autonomous vehicle are provided. In one example embodiment, a computer-implemented method includes obtaining sensor data indicative of a surrounding environment of the autonomous vehicle, the surrounding environment including one or more occluded sensor zones. The method includes determining that a first occluded sensor zone of the occluded sensor zone(s) is occupied based at least in part on the sensor data. The method includes, in response to determining that the first occluded sensor zone is occupied, controlling the autonomous vehicle to travel clear of the first occluded sensor zone.

A system and method of inspecting a static monitoring installation, installed in a traffic space. An evaluation circuit is able to create an image of the environment from a signal reflected from an object, wherein at least one reference value of a reference image of the environment is stored in the evaluation circuit, and the at least one reference value is formed from the reflected signals of at least one reference point for a reflected signal

A method for radar full blockage detection includes transmitting, via a transceiver, radar signals for object detection. The method also includes determining whether an object is detected within a first threshold distance based on reflections of the radar signals that are received. In response to a determination that the object is detected within the first threshold distance, the method includes determining whether the object is detected beyond a second threshold distance, based on the reflections of the radar signals. The second threshold distance is further away from the electronic device than the first threshold distance. In response to determining that the object is within the first threshold distance and not detected beyond the second threshold distance, the method includes determining that the transceiver is fully blocked by the object. upon a determination that the transceiver is fully blocked, the method includes modifying a wireless communication operation associated with the transceiver.

A method can be used for adaptive parking of a vehicle. A parking area is determined around a programmed destination of the vehicle. The parking area has more than one available parking spot for the vehicle. Parking data is acquired via a wireless communication network. The parking data for each parked vehicle includes a parking position and an individual sensing coverage of an environment sensor system of the respective parked vehicle scanning the traffic environment within the parking area. Available parking spots are ranked based on a calculated overall sensing coverage and a recommended parking spot is determined among the available parking spots based on overall sensing coverage of the traffic environment in the parking area.

A method for operating a headlight system of a motor vehicle, which during operation, illuminates an overall illumination area in the area surrounding the motor vehicle. At least two sensors are provided which detect objects in different associated sensor regions, the sensor regions of the sensors overlapping in an overlap region within the overall illumination area. The data of the sensors are fused to ascertain the existence of an object in the overlap region. Upon confirmation of the existence of the object, a zone in the overall illumination area in which the object is located is selectively excluded from illumination. A motor vehicle having a headlight system operated in this manner is also described.

Aspects and implementations of the present disclosure address challenges of the existing technology by enabling lidar-assisted identification and characterization of visibility-reducing media (VRM) such as fog, rain, snow, dust in autonomous vehicle applications, using lidar sensing. VRM can be identified and characterized using a variety of techniques, including analyzing a spatial distribution of low-intensity lidar returns, detecting pulse elongation of VRM-returns associated with reflection from VRM, determining intensity of VRM-returns, determining reduction of intensity of returns from various reference objects, and other techniques.
