Abstract: Techniques and apparatuses are described that implement electromagnetic vector sensors (EMVS) for a smart-device-based radar system. Instead of including an antenna array of similar antenna elements, the radar system includes two or more electromagnetic vector sensors. At least one of the electromagnetic vector sensors is used for transmission and at least another of the electromagnetic vector sensors is used for reception. Each electromagnetic vector sensor includes a group of antennas with different antenna patterns, orientations, and/or polarizations. An overall footprint of the two electromagnetic vector sensors (e.g., one for transmission and one for reception) can be smaller than antenna arrays used by other radar systems, thereby enabling the radar system to be implemented within space-constrained devices.

Abstract: An optical-electronic integrated RF leakage interference cancellation system and method for continuous wave radars belongs to the technical filed of radars. The optical-electronic integrated RF leakage interference cancellation system cancels the RF leakage interference by integrating of the microwave photonic link and the cable link. The microwave photonic link implements the phase adjustment, time delay adjustment and amplitude adjustment of the microwave signal tapped from the continuous wave source in the transmitter and realizes the cancellation matching conditions of the out of phase, the matching delay time and the same amplitude with the leakage interference signal. It has the advantages of broad frequency band, large bandwidth, and high tuning resolution, which enables the effective suppression of the RF leakage interference and ensures the high transmit-to-receive isolation for continuous wave radars.

Abstract: Disclosed are techniques for wireless sensing. In an aspect, a network node detects a collision between at least one wireless communication signal scheduled to be transmitted by the network node and two or more bundled radar reference signals scheduled to be transmitted by the network node, wherein the at least one wireless communication signal is scheduled to be transmitted during a gap between a first radar reference signal and a second radar reference signal of the two or more bundled radar reference signals; performs a collision avoidance operation based on detection of the collision, and transmits the two or more bundled radar reference signals.

Abstract: To provide a radar device capable of improving azimuth estimation accuracy by compensating the Doppler phase shift of a moving target in a TDMA FMCW MIMO radar device. Provided is a radar device that allows transmitting antennas to perform transmission by performing sequential switching such that antenna element numbers are anterior-posterior symmetrical centering on a reference time and synthesizes a beat signal at the reference time from a first beat signal received by a receiving antenna before the reference time and a second beat signal received after the reference time.

Abstract: Methods and systems for monitoring blood pressure in a person are disclosed. A method for monitoring a blood pressure in a person involves transmitting millimeter range radio waves over a three-dimensional (3D) space below the skin surface of a person, receiving radio waves on multiple receive antennas, the received radio waves including a reflected portion of the transmitted radio waves that is reflected by blood in a blood vessel in the 3D space, isolating a signal that corresponds to the portion of the transmitted radio waves that is reflected by blood in the blood vessel in response to receiving the radio waves on the multiple receive antennas, and outputting a signal that corresponds to a blood pressure level in the person in response to the isolated signal.

Abstract: Concepts and examples pertaining to reconfigurable radio frequency (RF) front end and antenna arrays for radar mode switching are described. A processor associated with a radar system selects a mode of a plurality of modes in which to operate the radar system. The processor then controls the radar system to operate in the selected mode by utilizing a plurality of antennas in a respective configuration of a plurality of configurations of the antennas which corresponds to the selected mode. Each configuration of the plurality of configurations of the antennas results in respective antenna characteristics. Each configuration of the plurality of configurations of the antennas utilizes a respective number of antennas of the plurality of antennas.

Abstract: An apparatus and method identify emitters. The apparatus includes a receiver, a parameter estimator, a database, and a correlator. The receiver receives an electromagnetic signal from an emitter and measures actual values of observed parameters of the electromagnetic signal. The parameter estimator surmises surmised values of unobserved parameters from the actual values of the observed parameters. The actual values of the observed parameters and the surmised values of the unobserved parameters characterize the emitter. The database stores one or more entries for each emitter. Each entry specifies an identifier of an emitter and exemplary values of the observed and unobserved parameters. The correlator matches the actual values of the observed parameters and the surmised values of the unobserved parameters with the exemplary values of one of the entries of the emitter from which the receiver receives the electromagnetic signal. The correlator outputs the identifier from this entry in the database.
