Tracker Backscatter Study.
Abstract
An experimental and analytical investigation of laser aerosol backscatter as it may affect hot-spot tracking was performed. Scattering measurements (forward and 177 degrees backscatter) were made with an infrared radiometer and the TRW Baseline Demonstration Laser at the Capistrano test site in Southern California as part of the JAN propagation test Series A and B. Twenty-two tests of backscatter were conducted at low power (800W) and high power (40kW) with three spectral filters in the radiometer. Mie scattering calculations were made to predict the scattering coefficient and compare it with the measured value. Meteorological data were provided by the JAN propagation council and included temperature, relative humidity, wind velocity, total extinction, and aerosol data. Extrapolations of the verified models to higher laster powers, on-axis tracking through an annular beam, and to maritime aerosols were made.
