SBIR 95-1 SOLICITATION
PROJECT SUMMARY
Proposal Number:
Project Title:
EYESAFE DUAL-DOPPLER LIDAR FOR HIGH RESOLUTION WIND MEASUREMENTS
Technical Abstract:
In this effort we propose to develop a dual-Doppler lidar system which will allow high-spacial
resolution 3-D wind measurements for several km around the lidar location. This instrument will
provide a measurement capability not previously available. In addition to detailed measurements
of regional 3-D winds with updates every few minutes, the dual-Doppler lidar will also be capable
of performing localized scans to probe the winds in specific areas in great detail and at faster
update rates. For example, high-spacial-resolution wind velocity can be obtained along the shuttle
landing facility runway center line or along the shuttle glide slope to an accuracy of <1 m/s and
with updates approximately every second. In the proposed effort Coherent Technologies, Inc. will
develop a dual-Doppler eyesafe coherent solid-state lidar system. During the Phase I effort,
analysis and computer simulations aimed at proving feasibility for the lidar system will be performed,
algorithms for optimization of the data from the two lidar views will be developed, and the preliminary
design for the dual-Doppler coherent lidar wind field sensor will be performed.
Potential Commercial Applications:
The proposed dual-Doppler lidar offers high potential for meeting critical sensor requirements for many
commercial and military applications requiring a detailed knowledge of the wind field state at short
to intermediate ranges. Potential commercial application include use of the sensor at airports for
detection of hazardous aircraft wake vortices and windshear. A very large market exists for the lidar
wind measurement sensor capable of autonomous operation.
