摘要
Abstract
Statistical modeling of benchmark submarine target strength(TS) is performed to cover the shortage of deter ministic forecast model.A TS density function model is established by Parzen window estimation.Then to get an unified and succinct expression of the density function model,typical distribution function models are used for optimal fitting of TS estimation.Ultimately an improved x2 distribution model with three parameters is established.Errors comparison indicates that this improved x2-distribution model can describe the submarine TS reasonably.This study may provide a reference for submarine target simulation.关键词
