In support of the Agency's SILEX optical-communications project, a first evaluation of the suitability of the Canary Islands (Spain) for an optical communications test range has been conducted. The low atmospheric attenuation ...

A Laser Doppler Anemometer system designed to measure two components of the velocity vector in fluids is presented. The scheme followed is the differential technique with backward scattering ...

This work describes the application of a commercial CAD software to implement load-pull techniques in the design of microwave mixers. This method is used to generate conversion-loss regions when a diode is pumped and ...

As an application of the dimensionless parameterization concept proposed earlier for the characterization of lidar systems, the universal assessment of lidar capabilities in day and night conditions is considered. The ...

The inversion of lidar returns from homogeneous atmospheres has been done customarily through the well-known slope method. The logarithmic operation over the range-corrected and system-normalized received signal used in ...

A European network of atmosphere sensors uses multi-wavelength elastic-Raman lidar instruments in its infrastructure.

To estimate the probability distributions of power fades, we consider two basic types of disturbance in electromagnetic wave propagation through atmospheric turbulence: wave-front intensity fluctuations and wave-front ...

When a large aperture is used to collect light propagated through the atmosphere, it performs an average operation on the irradiance fluctuations, resulting in collected-power fluctuations that are not as large as those ...

This paper establishes the relationship between the signal of a lidar system corrected for the incomplete overlap effect and the signal of another lidar system or a ceilometer for which the overlap function is unknown. ...
