  • Patent number: 11994617
    Abstract: An apparatus is for generating an emulated radar reflection signal of a target moving at a relative velocity. The apparatus includes a radar detector, an emulation transmitter, and a processor. The radar detector is configured to detect radar chirps emitted by a device under test (DUT), where the chirps are emitted at random time intervals. The emulation transmitter is configured to generate emulated radar reflection signals of the target being emulated. The processor is configured to generate control signals at intervals corresponding to the random time intervals at which the radar chirps are emitted by the DUT, where each control signal controls the emulation transmitter to generate a radar reflection signal. A relative phase of the control signals is adjusted according to a duration of each of the random time intervals between successive chirps and a magnitude and sign of the relative velocity of the target.

  • Patent number: 7852531
    Abstract: A system and method are provided for digital correction of a plurality of color channels and color image data. In color reproduction, a color image may be composed of a plurality of superimposed color channels in a color space. In order to assure the proper alignment of color channels and exemplary applications such as color printing, one or more of the plurality of color channels which compose a complete color image may be scaled to an output resolution, and corrected in order to ensure proper alignment and authentic reproduction of a color image. In place of a plurality of independent clocks, one for each channel, a single clock is provided for every channel, and additional unit is supplied to scale each channel according to independent characteristics.
