  • Patent number: 12288936
    Abstract: Disclosed is a method for fast automatic calibration of a phased array based on a residual neural network. A phase setting matrix is set and an amplitude and a phase of a array far-field complex signal are measured with a network analyzer to obtain an amplitude and phase vector of the array far-field complex signal. A real part, an imaginary part, and a magnitude of the far-field measured complex signal value are separated and normalized, and mapped to RGB three-channel image data. Datasets are automatically generated according to a preset amplitude-phase error range by a simulation software, the datasets are proportionally divided into a training set and a test set to be input into the residual neural network for training to obtain a calibration model. Measured data is input into the calibration model for automatic estimation of the amplitude-phase error of the phased array.

  • Patent number: 12276723
    Abstract: The present invention includes systems and methods for a continuous-wave (CW) radar system for detecting, geolocating, identifying, discriminating between, and mapping ferrous and non-ferrous metals in brackish and saltwater environments.

  • Patent number: 12274527
    Abstract: A precise cardiac data reconstruction method is provided, which may also be referred to herein as radar cardiography (RCG). RCG can reconstruct cardiac data, such as heart rate and/or electrocardiogram (ECG)-like heartbeat waveform signals wirelessly by using advanced radar signal processing techniques. For example, heartbeat and related characteristics can be monitored by isolating cardiovascular activity from strong respiratory interference in spatial spaces: azimuth and elevation. This results in significant improvements to pulse signal-to-noise-ratio (SNR) compared to conventional approaches, facilitating heart-rate variability (HRV) analysis.

  • Patent number: 12270898
    Abstract: Techniques and apparatuses are described that implement a smart-device-based radar system capable of determining characteristics of objects external to a vehicle, occupants within a vehicle, and objects proximal to an open-air vehicle. In particular, the system enables a smart device to perform many vehicle operations such as collision avoidance, occupant detection, and parking assistance in vehicle and open-air vehicle environments without integrated radar technology. By using a smart device to perform such actions, existing vehicles and open-air vehicles without integrated radar functionality may be able to leverage radar-based vehicle operations.

  • Patent number: 12265172
    Abstract: This document describes techniques and systems for a vertical microstrip-to-waveguide transition. A radar system may include a monolithic microwave integrated circuit (MIMIC) to generate electromagnetic signals and a printed circuit board (PCB) that includes a first surface, a microstrip, and a grounding pattern. The microstrip can be located on the first surface and operatively connect to the MIMIC. The grounding pattern is located on the first surface and made of conductive material. The radar system also includes a transition channel positioned over the grounding pattern, which includes a vertical taper between a bottom surface and a top surface. The transition channel defines a dielectric-filled portion formed by the grounding pattern and its interior surface. The described vertical transition can reduce manufacturing costs and support a wide bandwidth by tolerating an air gap at the transition-to-waveguide interface.
