The Marshall Space Flight Center MSFC has developed a scanning laser doppler vortex system SLDVS for use as an aircraft trailing vortex detection, tracking, and measuring system. This report describes the SLDVS design, development, and checkout at MSFC Previous efforts at MSFC had demonstrated the capability of laser Doppler systems to accurately measure remote wind velocity and turbulence. Tradeoff studies were performed to determine the optimum design parameters that met the program objectives. Computer simulations of the SLDVS performance were used in determining the optimum design parameters. The SLDVS scans both in range and angle. A real-time vortex display system is provided.
