Methods and apparatus are provided for controlling a movement of a sensor platform. The method includes receiving a desired position of the platform from a source. The desired position includes a first coordinate value and a second coordinate value. The method includes, based on the first coordinate value and the second coordinate value, calculating, by a processor, a first value associated with a first axis of rotation of the platform and calculating a second value associated with a second axis of rotation of the platform. The method includes outputting, by the processor, one or more control signals to at least one motor associated with the platform to move the platform based on the first value and the second value.

A radar apparatus includes transmitting means, receiving means, target detection means, and a cover member. The cover member is positioned opposite at least one of the transmitting means and the receiving means, such as to cover at least one of the transmitting means and the receiving means. The cover member is provided with a first face which is positioned opposite at least one of the transmitting means and the receiving means, and a second face which is on an opposite side from the first face and is not parallel to the first face.

A sensor device includes an emitter configured to emit radiation a detector configured to detect radiation reflected from an object and a cover having an interior surface facing the emitter or detector and allowing the radiation to pass through the cover. The sensor device also includes a heater with a wire-like trace directly deposited on the interior surface of the cover formed of a fluid comprising an electrically conductive material that was deposited onto a portion of the cover and cured. The heater has an electrically conductive connector pad formed with the heater by directly depositing and curing the fluid comprising the electrically conductive material directly on the interior surface of the cover simultaneously with forming the heater. The heater is positioned and arranged to sufficiently heat the cover while not blocking an area through which radiation must pass for proper operation of the emitter and the detector.

A radio wave reflection reducing sheet provided with a laminate having a first primary surface and a second primary surface is disclosed. The laminate has: a first resin foam layer having a thickness from 0.05 to 3.00 mm and a density from 0.10 to 0.85 g/cm.sup.3, and a second resin foam layer having a thickness from 0.05 to 3.00 mm and a density from 0.20 to 0.90 g/cm.sup.3. The density of the second resin foam layer is greater than the density of the first resin foam layer. The first resin foam layer and the second resin foam layer are disposed in this order from the first primary surface side.

A radar sensor having a frame, a housing arranged at the frame, a transmission and reception unit for high frequency signals arranged within the housing, wherein a radiation direction of the high frequency signals irradiated by the transmission and reception unit is rotatable about an axis of rotation. The radiation direction of the high frequency signals irradiated by the transmission and reception unit is substantially orthogonally oriented toward the axis of rotation, and the housing is supported at the frame rotatably about a pivot axis.

A sensor-cluster apparatus, in which a sensor configured to detect and collect external environment information is mounted in a case. The sensor-cluster apparatus includes a body member on which one kind or more of sensors are mounted on one surface thereof, a case in which an inner space is provided, and one surface thereof is opened to define an opening and on which the body member is mounted so that each of the sensors is exposed to the opening, and a position control device mounted inside the case to adjust a mounting position or a mounting angle of the body member.

A motor vehicle, in particular for a passenger car, having a support structure, a roof skin, which is disposed on the support structure, and at least one sensor module having at least one environment sensor for detecting a vehicle environment and having at least one housing for accommodating the environment sensor. The housing of the sensor module is disposed on the support structure and has a construction which collapses or is deformed when defined external forces are applied such that deformation forces, which are exerted by the sensor module on the support structure or on another roof module component, are reduced.

The present invention relates to a resin molded product having excellent impact resistance and weather resistance and low dielectric loss and a RADAR module including the same, wherein the resin molded product has a permittivity of 3.7 F/m or less and a dielectric loss of 0.023 or less in the frequency range of 77 GHz, has a high-speed impact strength according to ASTM D3763 of 400 kg.Math.m/s.sup.2 or greater, and has an electromagnetic wave transmission coefficient of −0.8 dB or greater in the frequency range of 77 GHz to 79 GHz.

Generally, the present disclosure relates to a forward deployed sensor system or, in a specific embodiment, a forward deployed radar (FDR) system. The forward deployed sensor system includes a radar system and may also include other types of sensors such as optical sensors, acoustic sensors including sonar, and electromagnetic sensors. Further, the forward deployed sensor system may also include a communication system such as a full spectrum receiver/transmitter, a ship to ship relay transponder, a satellite communication system, and global positioning system (GPS) capability.
