摘　　要：舰船尾流常作为对舰船跟踪识别的重要依据。受水文、试验装备等条件制约,国内开展海上尾流测量相关试验较少,对尾流全寿期几何与声散射特性的描述分析一直处于定性或半定量的阶段,同时鱼雷尾流自导仿真试验中的尾流模型尚有改进空间。为了掌握尾流几何特征发展规律,提供更准确具体的尾流模型,本文基于多组数据样本统计分析,采用多项式、高斯函数等数学表达式建立尾流几何特性全寿期的统计模型。本文开发的模型可用于声尾流目标的制导与识别相关研究,可为仿真试验中的尾流模型改进与应用提供参考。Ship wake is often used as an important basis for ship tracking and dentification.Due to the constraints of hydrological conditions,test equipment,and other conditions,there are few relevant tests on sea in China,and the description and analysis of geometric and acoustic scattering characteristics of the wake during it’s whole life are always in the qualitative or semi-quantitative stage.There is still room for improvement in the wake model of the torpedo wake self-conductance simulation test.In order to master the development law of wake geometric features,and provide a more accurate and specific wake model.This study is based on statistical analysis of the multiple data samples and adopted polynomial,Gaussian function and other mathematical expressions to establish the statistical model of the wake geometric characteristics of the whole life.The developed model can be used for the guidance and identification of the wake target,and can provide reference for the improvement and application of the wake model in simulation tests.
