动态海面红外视景仿真研究

摘要

Infrared scene simulation of sea wave plays a very important role in battlefield situation visualization and research of infrared search and track systems.To improve infrared scene simulation effect of sea wave,sea wave surface was modeled by using gerstner wave,and wave surface parameters were computed by directional ocean wave spectrum based on PM and SWOP direction expanding equation.According to sea wave surface infrared radiation characteristics,infrared radiation effect was simulated,and high fidelity infrared scene simulation of sea wave was achieved.The simulation results show that this method has a high application value in some areas.%动态海面红外视景仿真在战场红外视景重构以及红外跟踪制导装备研究方面有着极其重要的作用.为提高海面红外仿真效果,采用Gerstner波进行海浪波面建模,采用基于PM谱和SWOP方向扩展函数的海浪方向谱进行波面参数计算,根据海面辐射特性进行海面红外辐射效果模拟,实现了动态海面高逼真度红外视景仿真.仿真结果表明,该方法符合实际情况,具有较高的应用价值.
