Evaluation of EM Propagation Models Using Data from Wallops Island Experiment (2000)
Abstract
The Royal Navy and the United States Navy emphasise utilising the environment to achieve a tactical edge Such approaches are outlined in Sea Power 21 This thesis recognizes accurate characterisation of the physical battlespace as vital to concepts of both self-defence (Sea Shield) and strike (Sea Strike), Electromagnetic (EM) propagation is presented as a vital factor in the performance of a wide variety of ship, land, and airborne sensors and weapon systems Atmospheric influences on EM propagation are related to gradients of temperature and humidity within the atmosphere It is emphasised that modern maritime warfare is increasingly concentrated in the coastal theatre, an area in which atmosphere variability is often at maxima in both the vertical and horizontal, This thesis examines, using currently available technology and operational methods, how well the physical EM battlespace is described, Propagation models from the UK and US are used to evaluate the propagation environment within the coastal zone, using measured data, collected from the East Coast of the USA, at Wallops Island during 2000, as a comparison The main findings relate to the large potential errors, due the inability to measure and characterise the variability of the coastal environment under simulated, operational scenarios,
