摘要: Degraded visual environments are a cause of problems for surveillance systems and other sensors due to the reduction in contrast, range, signal. Fog is concern because frequency its formation along our coastlines; disrupting border security, shipping, surveillance, sometimes causing deadly accidents. reduces visibility by scattering ambient/active illumination light obscuring environment limiting operational capability. Sandia has created fog facility characterization testing optical systems. This 180 ft. 10 chamber with temperature control that can be filled fog-like aerosol using 64 agricultural spray nozzles. We will discuss physical how affected environmental controls at disposal. have recently made several improvements including present results these on conditions. instrumentation used characterization. In addition, we preliminary from work Sandia, leveraged this investigate polarized enhance range capability provides platform performing propagations experiments known, stable, controlled where demand.
