舰船红外仿真研究对舰船的红外隐身设计和提高舰船红外对抗能力而言具有重要意义.由于仿真计算量大、耗费计算时间过长,舰船红外仿真平台在实际应用中受到了不少限制.提出了一种基于“贡献因子”的辐射场计算算法,大幅度的降低了仿真程序的计算量,缩短了计算时间.“贡献因子”算法已经在船舶系统工程部开发的 RIS(Real-time Infrared Simulator,实时海面舰船红外热像仿真平台)1.0版的计算程序中得到了具体应用,大大提高了 RIS 红外仿真计算的速度.
The research of infrared simulation of naval ships is of great significance to the infrared stealth design of ships and the enhancement of the ship’s infrared confrontation capability. Due to the large amount of simulation calculations and the long time-consuming calculation, the infrared simulation platform for naval ships has been subjected to many practical applications A radiative field calculation algorithm based on “contribution factor ” is proposed, which greatly reduces the computational cost and shortens the computation time of the simulation program. “Contribution factor ” algorithm has been developed in the Department of Ship Systems Engineering RIS (Real-time Infrared Simulator, real-time surface ship infrared thermal simulation platform) version 1.0 of the calculation program has been specifically applied to greatly improve the speed of RIS infrared simulation.
