Abstract: An integrated circuit including an optical input, which can be coupled to an optical fiber, allowing an optical signal to be provided to the optical input via the optical fiber. The integrated circuit includes a controllable liquid crystal element, into which the optical signal can be coupled via the optical input. The integrated circuit is characterized by an optical waveguide arranged directly at the liquid crystal element, and a control device designed to activate the liquid crystal element to modulate its refractive index, thereby enabling at least partial coupling of the optical signal into the optical waveguide. The present disclosure also relates to a system and a method.

Abstract: A system and method for estimating current positions of sensor elements in an array sensor involve providing initial position estimates by an electronic computing device, transmitting a sensor signal into the surroundings, and receiving a reflected signal from at least one calibration target. The system determines the direction of arrival of the reflected signal and analytically estimates the virtual positions of the sensor elements based on this direction and a criterion of smallest residuum. The current positions are then estimated using the virtual positions and initial estimates. The technology further includes a computer program product, a computer-readable storage medium, and an array sensor configured to perform these functions.

Abstract: An antenna device for emitting and/or receiving electromagnetic radiation in a motor vehicle includes at least two sub-antenna groups arranged at a predefined first distance relative to one another. Each sub-antenna group includes at least one transmitting antenna and one receiving antenna, with a second distance between the at least one transmitting antenna and the one receiving antenna being smaller than the predefined first distance between the sub-antenna groups. This description also relates to a motor vehicle that incorporates the antenna device.

Abstract: Technologies and techniques for correcting a radar signal to determine a synthetic aperture. Data indicative of the radar signal is received, the radar signal having a sequence of echoes from a target region and being based on a sequence of transmission pulses. A movement of at least one target object in the target region is determined, and correction information for the radar signal is determined, based on the movement of the target object. An influence of the movement of the target object on the radar signal is reduced, based on the correction information to obtain a corrected radar signal.
