Comparison of Infrasound Wind Filter Designs for Airport Deployments

This paper focuses on using infrasound microphones to detect and localize distant infrasound emissions from tornadoes and clear air turbulence in support of aviation decision making. The key to the detection of distant infrasound is an ability to suppress the noise caused by the local winds blowing over the infrasound setup. Towards this, we are conducting a side-by-side comparison of several different wind filter designs. The objective of the comparison is to identify the most compact, easy to deploy, and easy to maintain filter that meets our infrasound detection needs for an eventual airport deployment.
