Hitoshi Nomi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Radar system, method of obtaining image, control method based on image data and monitoring method using milliwaves
    Patent number: 6762709
    Abstract: A plurality of sub-antennas in a two-dimensional plane antenna 11 or the like receive milliwaves from concerned object 20. An A/D converter 12 converts the received signal to digital data. A signal processor 13 executes signal processing on the digital data for displaying images on a monitor 15. Prior to the measurement, a calibration signal source 14 generates a calibration signal. A phase compensator 133 in the signal processor 13 obtains phase compensation data, and compensates measurement data.
    Type: Grant
