SBIR 95-1 SOLICITATION
An acoustic phased array radar system capable of simultaneously
obtaining components of the atmospheric wind with multiple beams of
acoustic waves is proposed for a research and development. The
proposed innovation, Hyper-Sodar, is a high performance wind profiler
utilizing a novel digital signal processing technique that cleverly
induces cancellation of noise components in the return signals. The
system is designed to provide high resolution wind measurements at
spatial scales of 10 m and at time scales of an order of 1 s with an
accuracy of better than 1 m/s in speed and 10 degrees in direction.
The objectives of the research are to test and evaluate the technical
merit of the design concept, and to develop design specifications for
the proposed system. The effort involves: (a) develop an acoustic
phased array antenna system capable of obtaining multiple backscatters
on a single transmission pulse, and (b) develop a fast digital signal
processor to accurately transform the backscattered signals into
components of a three-dimensional wind field.
It is anticipated that the proposed Hyper-Sodar will be successfully
developed, and that the innovation will be immensely beneficial to
NASA's on-going research efforts in improving the safety measures for
the space flight programs.
Potential Commercial Applications:
(1) Aviation Safety Application. Hyper-Sodar can be used to measure
wind shear, wake vortex, and detect microburst turbulence.
(2) Aerospace Safety Application. Hyper-Sodar can be used to provide
an extra margin of safety for the space flight programs, especially
during the landing of the space shuttle.
(3) Environmental Application. Hyper-sodar can be deployed to provide
remote wind measurements for monitoring the trajectories and dispersion
of airborne pollutants.
