Sensitivity of Radar Wave Propagation to the Marine Atmospheric Boundary Layer

Designers of radar use long term averages of meteorological conditions to assess system performance, but instantaneous conditions like strong moisture gradients, land breezes, and fronts can cause unpredictable propagation phenomena, such as ducts.  To better understand the relative importance of these effects, this study aims to quantify the sensitivity of propagation power to environmental parameters.  The study is performed utilizing a PE radar wave propagation simulation and computes its sensitivity to environmental inputs using the extended Fourier Amplitude Sensitivity Test.
