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。
Real-time Infrared Simulator (RIS) is a ship infrared simulation system with independent intellectual property rights for the research and development of ship infrared suppression and infrared confrontation. The system integrates the hull radiation field, exhaust smoke radiation field, sea background radiation, atmospheric transmission calculation and infrared seeker and other functional modules. The calculated spectral resolution of RIS simulation reaches 20cm-1, which ensures the accuracy of the radiation calculation of the atmosphere, plume and other gases. The use of RIS can simulate various weather conditions and weather conditions along the different viewing angles observed by the atmospheric transmission of infrared thermography. On this basis, the infrared stealth effect of the ship, the effect of different infrared suppression and infrared countermeasure devices, and the economic cost can be simulated and analyzed. The results of the sea voyage experiment verify the accuracy of the RIS simulation results.
