Abstract

Aerosol extinction is critical to EO sensor performance. Some information about extinction may be obtained from a visibility meter or from observing distant parts of the scene. However, this may be difficult under conditions of darkness, slant paths, clouds, smoke etc. Therefore, we investigate how a laser (for example in the form of a laser range finder) can be used to estimate atmospheric extinction at the laser wavelength. Translating this information to other wavelength regions may be done through established atmospheric models. The use of a laser to evaluate atmospheric attenuation offers an attractive way to achieve performance of various laser and passive electro-optical sensors. A laser weapon is for example very depending on the atmospheric propagation. The paper discusses and exemplifies lidar methods to derive extinction from measurements against targets in the scene or from atmospheric backscatter.
