An example system and method provides radiating into the 3D environment a millimeter wave (mmWave) radio frequency (RF) radiation signal that interacts with reflective surfaces, penetrable surfaces, scattering surfaces of the 3D environment, producing respective multipath components, determining information from two or more of the multipath components, including two among, or, optionally, all of angle of arrival (AoA), angle of departure (AoD), time of arrival, relative time of arrival (RTA), and phase and, based on the information and the received multipath components, performs computing the user device’s relative or absolute mobile device location in relation to the surrounding 3D environment, and providing images or video of the surrounding 3D environment to a display or a storage of the user’s mobile device, for displaying or storing.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) in a vehicle-to-everything (V2X) system may receive configuration information from an assisting node, such as a roadside unit (RSU), for calculating location information for a target UE in the V2X system. The assisting node may reflect one or more radar signals from the UE towards the target, and from the target back towards the UE according to the configuration information. That is, the assisting node may modify one or more waveform parameters of the reflection according to the configuration information. The UE may calculate location information for the target based on the reflection, such as by classifying the target as non-line-of-sight (NLOS) based on modified waveform parameters, location information of the assisting node, or both.

False detection of a ghost is prevented. A radar apparatus includes: transmission circuitry, which, in operation, transmits a radar signal; main reflective object detection circuitry, which, in operation, detects a main reflective object in a detection area using a reflected wave of the radar signal; in-area determination circuitry, which, in operation, determines a main area where a ghost caused by a reflective object outside the detection area and the main reflective object is located, the main area being inside the detection area; and auxiliary reflective object detection circuitry, which, in operation, detects a position of an auxiliary reflective object in the main area using a reception signal of the reflected wave of the radar signal, the auxiliary reflective object being located farther than the main reflective object on an extension of a line connecting the radar apparatus and the main reflective object.

This document describes techniques and systems to detect and localize NLOS objects using multipath radar reflections and map data. In some examples, a processor of radar system can identify a detection of an object using reflected EM energy and determine, using map data, whether a direct-path reflection associated with the detection is within a roadway. In response to determining that the direct-path reflection is not located within the roadway, the processor can determine whether a multipath reflection (e.g., a multipath range and multipath angle) associated with the detection is viable. In response to determining that the multipath reflection is viable, the processor can determine that the detection corresponds to an NLOS object. The processor can also provide the NLOS object as an input to an autonomous or semi-autonomous driving system of the vehicle, thereby improving the safety of such systems.

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.

A notification device of an approaching vehicle detects an approach of the other vehicle running a crossroad intersecting a run way of an own vehicle at an anterior intersection and an arrival direction thereof by a radar sensor and notifies a driver thereof. A reflection distance-acquisition part computes a reflection distance Xw according to a difference between absolute values of an X-axis component of a relative position acquired by the radar sensor and an X-axis component of a converted relative position acquired by a relative-position acquisition part of the other vehicle in an X-Y rectangular coordinates with its origin at a location and a Y-axis in a traveling direction of the own vehicle. A notification restriction part forbids a notification of the arrival direction of the other vehicle when the Xw has not fluctuated for a predetermined time or longer.
