基于板块元法的水下目标回波亮点仿真

摘要

When using the traditional highlight model to simulate the echo of underwater targets, the precision is not high. Aiming at this problem, an echo simulation method hased on the planar element method is proposed in this paper. The three-dimension shape model of submarine was constructed. Using the planar element method, the time-domain echo of submarine is calculated. The simulation results show that the model is practicable and can be used for the detection and recognition of underwater targets research.%针对传统亮点模型模拟水下目标回波亮点精确度不高的问题,给出了一种运用板块元法仿真实现目标回波亮点的方法.采用建模软件对潜艇模型进行精确几何建模,运用板块元法计算了潜艇目标的高频回波数据.仿真结果表明:该方法可以更真实地反应水下目标的回波亮点特性,为水下目标的探测与识别提供数据支持.
