Simulation and Application of Sea Clutter in the Condition of Evaporation Duct
摘要
Abstract
Evaporation duct is one of anomalous refractivity structure which ofen occur at ocean atmosphere. When a duct is present ;it can increase the electromagnetic wave's propagation length with less propagation loss than a stand atmosphere;but boost up the received radar sea clutter at the same time. This paper deduces the processes of simulating sea clutter in theory detailedly;which include the modeling of sea-clutter backscattering cofficient and using the PE to calculate propagation loss in the condition of evaporation duct;and then implement the simulation. At last introduce the application of simulating sea clutter to the " rafractivity-from-clutter".关键词
