Wake Vortex Lidar Monte Carlo Simulation and Visualization Tool

Light Detection and Ranging (LIDAR) sensors have been successfully demonstrated and implemented capabilities to detect and measure wake vortices in and around the terminal area. Although LIDAR systems have been used to measure wake vortex strength and position in NASA and FAA measurement campaigns and too little is known about their accuracy in quantifying location and strength in different regimes. Field data analysis suggests that strength may be commonly overestimated compared to theoretical models, but no study has been conducted to determine the validity and accuracy of the sensing techniques to determine these estimates. Additionally, these uncertainties cannot be determined since no other remote sensing system has been verified to accurately measure and characterize the wake vortices. A risk with no quantitative assessment is that it may negatively impact the separation standards. Aerospace Innovations, LLC proposes to design and develop a physics-based Monte Carlo LIDAR Simulation and Visualization (LiSiVi) Tool to provide NASA and industry researchers the ability to accurately model the performance of LIDAR based wake vortex sensing systems. The significance of this innovation is that it combines the advancement of knowledge in the wake vortex modeling research and the laser technology areas.
