Abstract
To compute the field and estimate the time delay of multi-path signal in sea evaporation duct ( SED) ,a method of modeling communication bandwidth channel is presented. Algorithm of ray tracing in subsections is proposed. A method of separating arriving multi-path signal and computing field is put for﹣ward,considering space wave diffusion, rough surface reflection and reception sphere. Characteristics of time delay estimation,system design and strategies of usage are studied. Feasibility of the constructed meth﹣od is verified by numerical experiments. The new method provides an effective way of link budget and per﹣formance analysis in SED communication to get expectable performances,with proper selection of signal fre﹣quency,bandwidth and energy surplus.关键词
