潜艇的物理特征是航空反潜传感器搜索潜艇的主要依据, 对潜艇特征进行准确的仿真建模能够实现 对潜艇的有效分析。本文以水下航行状态下的潜艇为背景，基于潜艇外部环境和内部工况因素，提出了一种尾 流特征仿真建模方法。通过仿真建立了潜艇内波尾流特征仿真模型和热尾流模型，仿真结果表明，所得模型从 雷达目视和红外探测两个维度模拟了水下潜艇的尾流特征，能够有效反映水下航行潜艇尾流特征。

Simulation Modeling Method for Underwater Submarine Wake Characteristics

The physical characteristics of submarines are the main basis of aerial anti- submarine sensors to search submarines. Accurate simulation modeling of submarine characteristics can enable an effective analysis of submarines. With the submarine in underwater navigation as the background, based on the external environment and internal working conditions of the submarine, a simulation modeling method of wake characteristics is proposed. The simulation model and thermal wake model of submarine internal wave wake characteristics are established by simulation. The simulation results show that the obtained model simulates the wake characteristics of underwater submarines from the two dimensions of radar visual and infrared detection, which can effectively reflect the wake characteristics of underwater submarines.
