“贡献因子”算法:一种快速的舰船红外辐射仿真算法

"Contribution factor"algorithm:a rapid algorithm for infrared simulation of marine ship

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 infrared simulation study on marine ship is of great meaning for infrared concealing design of ship,which will enhance the survival ability of ship under infrared threats.The infrared simulation of marine ship has been limited in engineering practices because of its huge computation load and long computation period.A rapid algorithm based on'contribution factor'is described in this paper,which can decrease the computation load and reduce the computation period greatly.The'contribution factor'algorithm has been applied in the RIS (Real-time Infrared Simulator) 1.0 edition,which has increased the simulation speed of RIS evidently.
