  • Method for detection of movement of a specific type of object or animal based on radar signals
    Patent number: 8682821
    Abstract: A method of detecting movement includes using a radar sensor to monitor a space, and receiving an output signal from the radar sensor. A Fourier transform is performed on the output signal to produce a frequency domain signal spectrum. The frequency domain signal spectrum is transformed into an acoustic domain signal. It is decided whether the output signal is indicative of movement of a predetermined object or a non-human animal dependent upon at least one feature of the acoustic domain signal and at least one spectral feature of the signal spectrum.
    Type: Grant
    Filed: August 8, 2011
    Date of Patent: March 25, 2014
    Assignee: Robert Bosch GmbH
    Inventors: Diego Benitez, Zhaozhang Jin

  • Method for human only activity detection based on radar signals
    Patent number: 7924212
    Abstract: A method of detecting human presence includes using a radar sensor to monitor a space, and receiving an output signal from the radar sensor. A Fourier transform is performed on the output signal to produce a signal spectrum. It is decided whether the output signal is indicative of human activity dependent upon at least one acoustic feature of the signal spectrum and at least one spectral feature of the signal spectrum.
