Modelling of N21P emission rates in aurora using various cross sections for excitation [PDF]
Annales Geophysicae, 2009 Measurements of N21P auroral emissions from the (4,1) and (5,2) bands have been made at high temporal and spatial resolution in the region of the magnetic zenith. The instrument used was the auroral imager ASK, situated at Ramfjordmoen, Norway (69.6 N,

Wind Turbine Radar Cross Section [PDF]
International Journal of Antennas and Propagation, 2012 The radar cross section (RCS) of a wind turbine is a figure of merit for assessing its effect on the performance of electronic systems. In this paper, the fundamental equations for estimating the wind turbine clutter signal in radar and communication systems are presented.

A Model for the Backscattering From a Canonical Ship in SAR Imagery
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2016 Synthetic aperture radar (SAR) sensors represent one of the most effective means to support activities in the sector of maritime surveillance. In the field of ship detection, many SAR-based algorithms have been proposed recently, but none of them has ...
