Patent ID: 8174930

Claim:
A housing for a phased array monostatic sodar system with a transducer array that sequentially emits and receives multiple generally conical main beams of sound along different primary axes, the housing comprising: an enclosure comprising a plurality of upwardly-directed sidewalls that together define a single interior volume that is essentially open to the atmosphere at the top, to emit and receive the beams; wherein the enclosure further defines an opening, and at least the opening shape closely conforms to the conical shape of at least a portion of one main beam: wherein at least some of a set of inside surfaces of the plurality of upwardly-directed sidewalls of the enclosure are shaped to closely conform to at least portions of each of the beams; and wherein at least some of the set of inside surfaces of the plurality of upwardly-directed sidewalls of the enclosure are generally partially elliptical in cross section, to closely conform to an angled conical beam contour.
