摘要： In accordance with an embodiment, a method includes: determining a harmonic spectrum of an intermediate frequency (IF) signal of a radar sensor; determining an undesired signal component of the IF signal caused by at least one of a crosstalk of the radar sensor or a near-range obstacle in a field of view of the radar sensor based on the harmonic spectrum; and determining a calibrated signal having a reduced contribution from the undesired signal component based on the undesired signal component and the IF signal.

摘要： This document describes techniques and systems that enable a smartphone-based radar system for determining user intention in a lower-power mode. The techniques and systems use a radar field to enable the smartphone to accurately determine the presence or absence of a user and further determine the intention of the user to interact with the smartphone. Using these techniques, the smartphone can account for the user's nonverbal communication cues to determine and maintain an awareness of users in its environment, and only respond to direct interactions once a user has demonstrated an intention to interact, which preserves battery power. The smartphone may determine the user's intention by recognizing various cues from the user, such as a change in position relative to the smartphone, a change in posture, or by an explicit action, such as a gesture.

摘要： An apparatus for is disclosed for mitigating radar-to-radar jamming within a shareable time slot. The apparatus includes a wireless transceiver configured to transmit a first radar signal during a first shareable time slot. The first radar signal has a start time that is delayed relative to a start time of the first shareable time slot by a first time delay. Additionally, the wireless transceiver is configured to receive a first receive signal during the first shareable time slot and detect a potential object based on the first receive signal. Furthermore, the wireless transceiver is configured to transmit, using the first antenna, a second radar signal during a second shareable time slot. The second radar signal has a start time that is delayed relative to a start time of the second shareable time slot by a second time delay. The second time delay is different than the first time delay based on the detection of the potential object.

摘要： An electronic device using a millimeter wave, according to various embodiments, includes a communication circuit and at least one processor. The at least one processor can be configured to: control the communication circuit so that a first millimeter wave signal is output at a first strength; use the communication circuit so that the first millimeter wave signal receives a first reflection signal reflected by an object; confirm whether the object is positioned within a first distance from the electronic device; determine the strength of a second millimeter wave signal to be a second strength corresponding to a second distance between the electronic device and the object, the second distance being shorter than the first distance; and control the communication circuit so that the second millimeter wave signal is output at the determined second strength.

摘要： Antenna switching can improve wireless connectivity of a computing device by selectively enabling one or more antenna modules. The antenna modules can be positioned along edges of the computing device to reduce the likelihood that multiple antenna modules are obstructed at once. Each antenna module can include an ultra-wideband (UWB) sensor and communication antenna (e.g., a Wi-Fi antenna) for wireless connectivity. A radio frequency (RF) controller of the computing device causes the UWB sensors to perform a UWB handshake with a wireless access point for position detection. Each UWB sensor is further configured to detect an obstruction proximal to the corresponding antenna module based on time-of-flight (ToF) and angle-of-arrival (AoA) measurements. In some cases, the RF controller can also perform gesture detection by the UWB sensors.

摘要： A computer-implemented method, a computer system and a computer program product refine service inquiries through an understanding of user context. The method includes receiving a service inquiry from a user on a computing device. The method also includes capturing movement data within a user environment. The movement data is selected from a group consisting of audio data, video data and telemetry data extracted from a second device in the user environment. The method further includes determining a user context by correlating motion and position of the user with respect to the user environment. In addition, the method includes generating a set of predicted modifications to the service inquiry based on the user context. Lastly, the method includes displaying the set of predicted modifications to the service inquiry on the computing device.

摘要： A system includes a memory configured to store a two-dimensional data structure that includes radar data arranged such that radar data of a first transmitter is separated from radar data of a second transmitter by a Doppler offset in the two-dimensional data structure. The system also includes a data fetch mechanism that includes a lookup table (LUT) applied on either of two dimensions. The lookup table is configured to store a data fetch location in the two-dimensional data structure, where the data fetch location indicates a location from which to fetch a subset of the radar data from the two-dimensional data structure and the data fetch mechanism is configured to fetch the subset of the radar data from the two-dimensional data structure based on the LUT. The system includes a processor configured to perform a fast Fourier transform (FFT) on the fetched subset of the radar data.

摘要： A radar system for tracking UAVs and other low flying objects utilizing wireless networking equipment is provided. The system is implemented as a distributed low altitude radar system where transmitting antennas are coupled with the wireless networking equipment to radiate signals in a skyward direction. A receiving antenna or array receives signals radiated from the transmitting antenna, and in particular, signals or echoes reflected from the object in the skyward detection region. One or more processing components is electronically coupled with the wireless networking equipment and receiving antenna to receive and manipulate signal information to provide recognition of and track low flying objects and their movement within the coverage region. The system may provide detection of objects throughout a plurality of regions by networking regional nodes, and aggregating the information to detect and track UAVs and other low flying objects as they move within the detection regions.
