There is described a ultra-wide band (UWB) communication device, comprising:

i) a UWB antenna, configured to receive a UWB signal from a further UWB communication device, and
ii) a control device, configured to
iia) determine an angle of arrival (β) based on the received UWB signal,
iib) determine a distance between the UWB communication device and the further UWB communication device, and thereby
iic) compensate for a distance determination disturbance using the determined angle of arrival (β).

Further, a UWB communication system and a method of determining a distance are described.

A system includes a computer including a processor and a memory. The memory includes instructions such that the processor is programmed to: receive, from a radar sensor of a vehicle, radar data indicative of a stationary object proximate to the radar sensor; receive, from a non-radar sensor of the vehicle, vehicle state data indicative of a vehicle state, the vehicle state data indicative of at least a longitudinal velocity and a yaw rate of the vehicle; determine an orientation estimate and an offset estimate of the radar sensor based on the radar data and the vehicle state data; and determine whether to actuate a vehicle system based on at least one of the orientation estimate or the offset estimate.

A radar system for air volume surveillance, the radar having a transmitter and receiver with separate antennas. The receiver aperture being relatively large compared with the transmitter aperture such that the receiving beam is narrower than the transmitting beam, which itself is relatively small compared with the volume to be surveyed. Multiple receiving beams can be configured so that collectively they substantially match the angular volume of the transmitting beam; and in which the transmitter is arranged, when operating, to transmit a signal with a duty cycle greater than fifty percent.

A vehicle passenger detection device, a system including the same, and a method thereof are provided. The vehicle passenger detection device includes a processor configured to determine a location of a passenger per at least one or more seats based on strength of radar signals reflected from the at least one or more seats including medium with different reflection characteristics and a storage storing information associated with strength of a radar signal for each distance and information associated with strength of a radar signal according to the reflection characteristics of the medium.

The invention relates to a guidance system for leading an aircraft to a reference point, characterised in that it comprises: An active beacon capable of emitting a first electromagnetic signal in a first emission cone, defined by an apex coinciding with the reference point, a first beam angle and a first axis corresponding to an emission direction; and a multi-beam radar, installed on board the aircraft, operating in reception mode and capable of performing deviation measurements on a signal received from the active beacon, the multi-beam radar comprising an antenna adapted for receiving in at least two spatially separate reception cones.

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In some aspects, the apparatus may be a user equipment (UE) or a component thereof; however, in some other aspects, the apparatus may be a base station or a component thereof. The apparatus may be configured as a wireless node that configures an intermediary apparatus to reflect signals for the wireless node and another wireless node. The apparatus may be further configured to communicate a set of sensing signals with the other wireless node using the intermediary apparatus. The apparatus may be further configured to sense an object based on a set of measurements associated with the set of sensing signals.
