摘要

摘要: 针对板块元法计算潜艇目标强度时积分分母可能为零, 从而导致计算结果不稳定的问题, 文中将Gordon积分算法用于潜艇目标强度的预报仿真, 并针对复杂目标简化面元遮挡判断流程, 首先对刚性球体进行建模计算, 其次对Benchmark潜艇进行3D建模, 运用改进板块元法对潜艇目标强度进行预报。仿真结果表明, 改进模型的计算结果更加稳定, 能够较好反映潜艇目标强度的特征。

Abstract: Aiming at the instability in computing submarine target strength with the planar element method in case the integral denominator is zero, Gordon integral algorithm is used for submarine target strength forecast, and the process of planar occlusion judgment for complicated target is simplified. Firstly, a rigid sphere is modeled. Then, a 3D model of Benchmark submarine and a forecast model of submarine target strength based on the improved planar element method are built to forecast submarine target strength. Simulation results show that the proposed forecast model gains more stable computation, and the obtained data can well reflect the features of submarine target strength.
