Patent number: 11860265Abstract: A method for extracting spatial resolution and/or velocity resolution of a single-input single-output radar acquiring raw radar data with a frequency scanning antenna is provided. The method includes steering a radar beam with the aid of the frequency scanning antenna with respect to an area to be illuminated by the radar, and dividing the area into at least two angular sectors. In this context, the at least two angular sectors are configured in a manner that the at least two angular sectors overlap with respect to each other.Type: GrantFiled: July 28, 2021Date of Patent: January 2, 2024Assignee: Stichting IMEC NederlandInventors: Rainer Oliver Hornung, Peng Zhang, Marco Mercuri, Paul Mateman, Lichen Yao

Patent number: 11480654Abstract: Example embodiments relate to radar transceivers. One embodiment includes a radar transceiver. The radar transceiver includes a chirp generator for generating a chirp having an initial frequency and a final frequency. The radar transceiver also includes a controllable variable gain amplifier having an input connected to an output of the chirp generator. Further, the radar transceiver includes a control unit connected to a control input on the chirp generator and to a control input on the controllable variable gain amplifier. The control unit is adapted to output a first control signal to the chirp generator such that the chirp generator starts generating the chirp. The control unit is also adapted to output a second control signal to the controllable variable gain amplifier such that the controllable variable gain amplifier starts increasing an amplification in the controllable variable gain amplifier from a first amplification level to a second amplification level.Type: GrantFiled: February 13, 2020Date of Patent: October 25, 2022Assignee: Stichting IMEC NederlandInventors: Yao-Hong Liu, Marco Mercuri

Publication number: 20210275035Abstract: A method for automatic multi-object localization and/or vital sign monitoring is provided. The method comprises the steps of receiving a radar signal in order to form a corresponding observation matrix, reducing noise by applying singular value decomposition to the observation matrix, processing the result of the singular value decomposition by an independent component analysis in order to estimate the corresponding sources, and estimating propagation channels of the estimated sources by minimizing the corresponding residual error based on the observation matrix and the estimated sources.Type: ApplicationFiled: March 8, 2021Publication date: September 9, 2021Inventors: Yiting LU, Marco MERCURI

Patent number: 11051703Abstract: A method of detecting a vital sign comprising at least one of a heart rate and a respiratory rate of a subject is provided. In one aspect, the method includes transmitting a radio frequency signal towards the subject; and receiving a reflected signal from the subject, wherein the transmitted signal is reflected by the subject and Doppler-shifted due to at least one of the heart rate and the respiratory rate to form the reflected signal. The method also includes mixing the reflected signal with a first reference signal; and providing a vital sign carrying signal based on the mixing to a first input of a phase or frequency comparator. The method further includes generating an adjustable second reference signal and providing the reference signal to a second input of the phase or frequency comparator; and generating an output signal, by the phase or frequency comparator.Type: GrantFiled: February 12, 2018Date of Patent: July 6, 2021Assignee: Stichting IMEC NederlandInventors: Yao-Hong Liu, Marco Mercuri
