指挥台围壳雷达隐身性数值模拟

Numerical simulation for the stealth performance of submarine sails

  • 摘要: 对潜艇指挥台围壳在水面航行状态和半潜航行状态下的雷达隐身性进行研究。基于高频法,应用CATIA和MATLAB软件对三元流线型指挥台围壳和传统的直壁式指挥台围壳的雷达散射截面积(RCS)特性进行数值模拟和对比分析,并在此基础上进行雷达发现概率的计算。研究指挥台围壳的探测概率随距离变化的关系和指挥台围壳在2种航行状态下各重点探测角域探测概率的变化关系。研究表明,对指挥台围壳进行三元流线型设计并配合低矮化设计后,能明显改善潜艇指挥台围壳的雷达隐身性。

     

    Abstract: This paper studies the stealth properties of sails on the water and underwater. Based on the high-frequency method, it compares the Radar Cross Section (RCS) features of the conventional straight wall sail and the advanced 3D sail. Using CATIA and MATLAB, the numerical simulation of the RCS characteristics of sails and the calculation of radar detection probability are conducted, and the influence of different distances and angle territories on radar detection probability is discussed. The results show that the stealth performance of the advanced low-3D sail is considerably superior to that of the conventional straight wall sail.
