摘要： Systems and methods for scanning concealed surface and detecting concealed objects using a radar. A radar-based sensor unit has an array of transmitters and receivers which transmit a beam of electromagnetic radiations towards a subject being scanned and receive the reflected electromagnetic signals. A processing unit receives raw complex image data from the radar unit and processes the data for detecting specific concealed objects. A display unit displays images representing the concealed object. A database stores the processed data from the processing unit along with the raw complex image and the processed image data. Stored data may be used to train the processing unit for accurately detecting the specific concealed objects. A communicator may transmit notifications through a communication network.

摘要： Target monitoring and alert systems for identifying and tracking targets within radar data. Raw frame data is filtered to remove data relating to reflections from static objects. Moving targets are identified in the filtered data and their location is tracked over time generating target data. Neural networks may process the target data, calculate a fall likelihood score and generate a fall-alert if this is above an alert-threshold. A person identification module may extract the position and motion characteristics of each target from the data and generate a probabilistic identification of the target with a person.

摘要： Systems and methods for providing wide field-of-view radar arrays. Quadrature phase-shift keying (QPSK) beam forming reduces side lobes by applying a phase shift to transmitted signals to selected transmitting antennas. Super-hemispherical radar coverage at high gain in both broadside and end-fire directions is provided by beam directing elements mounted to a printed circuit board.

摘要： Methods and systems for reducing and eliminating the effects of reference signal leakage in multi-module radio-frequency systems, particularly for radio-frequency integrated-circuit devices. Isolation is provided by frequency shifting, by binary phase-shift keying of reference signals to furnish different reference signals with unique signatures to enable separation and discrimination, and by backwards sending of reference signals from receiver to transmitter to avoid contamination of receiver signals by leakage of transmitter reference signals. In addition to improving calibration, methods of the present invention also provide noise reduction in certain multiple-module radio frequency systems.
