实时海面舰船红外热像仿真平台

Real-time Infrared Simulator of marine ship

实时海面舰船红外热像仿真平台(Real-time Infrared Simulator,RIS)是针对舰船红外抑制和红外对抗研究开发的一款具有自主知识产权的舰船红外仿真系统。该系统集成了船体辐射场、排气烟羽辐射场、海天背景辐射、大气传输计算和红外导引头等功能模块。RIS仿真计算的光谱分辨率达到了20cm-1,保证了大气、烟羽等气体辐射传输计算的精度。利用RIS能够模拟各种天气状况和气象条件下沿不同视角方向观测时经大气传输后的红外热像。在此基础上,可以对舰船的红外隐身效果、不同红外抑制和红外对抗装置的使用效果以及经济成本进行仿真分析。海上航行实验的测量结果验证了RIS仿真结果的精度。

RIS is developed for the study of IRSS （Infrared Signature Suppression） and IRCM （Infrared Counter-Measure）. It is integrated with the functional modules for hull radiation, stack plume radiation, seasky background radiation, atmospheric transmission and infrared seeker.The spectrum resolution of RIS is 20 cm^-1, which can accurately simulate and analyze the 3D infrared signature of marine ship under different weather conditions. Using this simulator, the detailed IR signature management studies will be implemented, which includes IR suppression tradeoff studies, detailed susceptibility analysis and cost benefit analysis.The simulation results have been verified by the voyage experiment.
