摘要： A system and method for monitoring a person within a defined area by detecting breathing, or the lack thereof. Breathing is detected using radar signals, camera signals and/or microphone signals. The radar signals, camera signals and/or microphone signals are analyzed to determine if the subject person is moving, and if not moving if the person is breathing or not-breathing. An alarm is generated should the reflected radar signals, the camera signals and the microphone signals all simultaneously indicate no movement and no movement of the subject person in the defined area for a selected period of time.

摘要： Disclosed are examples related to non-destructive examination of tires using radar tomography. A radar signal can be used to illuminate a portion of a tire. Reflected radar signals can be received and used to generate a 3D image of at least the portion of the tire. The radar signals can illuminate a tread of the tire, an innerliner of the tire, and/or one or both sidewalls of the tire. The 3D image can include structural information of the tire that can be used to identify defects or damage in the tire. The examination can be conducted on new tires during fabrication, on existing tires during operation, and/or on used tires during refurbishment.

摘要： A method of performing vibrational radar backscatter communications includes transmitting radar waveforms at millimeter wave frequencies, receiving, from a vibrating transponder, vibrational backscatter of radar waveforms, performing synchronization on the vibrational backscatter to determine a start of an encoded communication message sequence, calculating a predicted symbol sequence based on the encoded communication message sequence, identifying, from one or more predetermined messages, an actionable message from the predicted symbol sequence, and communicating the actionable message to a display of a vehicle or causing the vehicle to take an action. This method can also be performed on a computing system that includes a processor, memory, and instructions stored in the memory and the method can be stored on computer readable storage media.

摘要： Remote recovery of acoustic signals from passive sources is provided. Wideband radars, such as ultra-wideband (UWB) radars can detect minute surface displacements for vibrometry applications. Embodiments described herein remotely sense sound and recover acoustic signals from vibrating sources using radars. Early research in this domain only demonstrated single sound source recovery using narrowband millimeter wave radars in direct line-of-sight scenarios. Instead, by using wideband radars (e.g., X band UWB radars), multiple sources separated in ranges are observed and their signals isolated and recovered. Additionally, the see-through ability of microwave signals is leveraged to extend this technology to surveillance of targets obstructed by barriers. Blind surveillance is achieved by reconstructing audio from a passive object which is merely in proximity of the sound source using clever radar and audio processing techniques.
