Abstract
A wind measurement apparatus comprises: a frame assembly; four transducers mounted to the frame assembly such that their locations serve as vertices of a regular tetrahedron; and a reflector assembly mounted to the frame assembly, positioned substantially at a center of said regular tetrahedron to allow for airflow between the reflector assembly and the transducers. The reflector assembly comprises a reflector element provided as a solid that has eight vertices and six substantially identical concave faces that serve as reflector surfaces and that is oriented such that each transducer is facing a respective vertex of the reflector element. Each transducer is arranged to: transmit a TX beam towards the reflector assembly such that the TX beam meets the three reflector surfaces that meet at the vertex of the reflector element faced by the transducer, and receive, via said three reflector surfaces, partial reflections of TX beams originating from other transducers.
