摘要： The present disclosure generally relates to a multistatic radar system and a method for a spatially resolved detection of an object under test. The multistatic radar system includes an at least two-dimensional multistatic array of antenna elements having an at least partially shared coverage area. At least one data processing circuit is coupled to the array. Analog and/or digital beamforming is performed thereby obtaining at least one image of the object under test at least partially being located within the shared coverage area. Processing the image obtained is used to resolve at least one scattering center of the object under test. A spatially resolved scattering center distribution is determined based on the image obtained.

摘要： A test system for testing a device under test (DUT) with a graphical user interface (GUI) and a touch-sensitive display is described. The test system includes a stimulation layer configured to selectively generate a stimulus signal in at least one area of the touch-sensitive display. The stimulation layer is at least partially transparent. The test system further includes at least one camera configured to capture at least one image of the GUI displayed on the touch-sensitive display through the at least partially transparent stimulation layer. The test system further includes an artificial intelligence (AI) circuit connected with the at least one camera and the stimulation layer. The AI circuit is configured to recognize at least one activatable element of the GUI based on the at least one image captured, and is configured to control the stimulation layer to selectively generate the stimulus signal based on the at least one recognized activatable element, such that a touch and/or or a gesture is imitated.

摘要： A system for correcting phase noise and/or drift, the system includes an optical signal module being capable of amplitude modulating the optical signal while being phase- and/or frequency-shifted. Further, the system includes a beam splitter capable of separating at least backward travelling waves based on polarization.

The system has a partially reflecting reflector capable of creating a backward travelling wave as well as a photodiode capable of receiving the backward travelling wave. The photodiode is capable of generating a detection signal used for detecting phase noise and/or drift in the backward travelling wave.
