Abstract: A wind measurement apparatus comprises: cover and base portions arranged to allow for airflow therebetween; N receivers on the cover portion; a transmitter on the cover portion at a substantially equal distance from each of the N receivers; and a reflector assembly on the base portion. The reflector assembly is divided into N concave reflector portions. Each receiver is associated with one of the reflector portions. The reflector assembly and the base portion are disposed such that the transmitter is spatially aligned with a center point of the reflector assembly and each receiver is spatially aligned with the associated reflector portion. The transmitter is arranged to transmit a TX beam towards the reflector assembly such that the TX beam meets each of the reflector portions. Each of the receivers is arranged to receive, via the associated reflector portion, a reflection of a TX beam portion that meets the reflector portion.

Abstract: An antenna assembly includes first and second feed antennas and a lens element. The first feed antenna is arranged to transmit outbound radio waves of a transmitter beam. The second feed antenna is arranged to capture a received RF signal. The lens element is arranged to collimate the transmitter beam and to focus the receiver beam. The first and second feed antennas are disposed on a conductive ground plane that is offset from a back end of the lens element by a predefined distance in direction of a center axis of the lens element. A volume between the back end of the lens element and the ground plane comprises material that has a refractive index that is smaller than that of the lens element for converging the outbound and inbound RF beams between the back end of the lens element and the first and second feed antennas.

Abstract: A method and apparatus for calibrating an optical surface condition monitoring system (1). Light beams at different wavelengths (λ1, λ2) are emitted to a reference substrate (2) at different distances (L1, L2) as well as to sample substrates (5) at a specific distance (Lspecific). Subsequently, ratios between the signals scattered back from the reference substrate (2) and the signals scattered back from the sample substrates (5) are calculated. Then, input data regarding a measurement distance (Lmeasurement) between a target surface (8) to be monitored, for example a road, and the receiver (3) of the system (1) is provided. Further, a preset program is selected. Dry calibration of the system (1) can then take place based on the calculated ratios, the measurement distance (Lmeasurement) and the selected program. Dry calibration can be calculated without having to perform an actual dry calibration in the field and no dry calibration plate or dry spot of the target surface (8) is required.
