为了检验近红外制导炸弹的命中精度, 通常在实验室进行半实物仿真试验, 需要研究近红外目标仿真模型, 将其置入目标模拟器中, 由近红外导引头跟踪目标, 仿真制导炸弹识别、跟踪、击中目标的全过程。基于仿真建模原理、理论和方法, 研究了环境建模、地形地物建模、天空背景建模、海天背景建模、雨雪特效建模和近红外目标建模等技术, 建立了多种静态、动态仿真模型, 以及仿真模型的驱动程序, 实现动态、逼真地显示仿真模型, 用于近红外制导炸弹的半实物仿真试验。

In order to check the attack accuracy of guided bombs, a hardware-in-loop experiment was conducted in the laboratory. The model simulating the near-infrared region target, which is input into the target simulating equipment, requires additional research. The seeker scans and tracks the target model. The process of a guided bomb scanning, tracking, and attacking a target was simulated. Based on simulation principles, theories, and methods, the technologies for environmental modeling, including the particular effects of terrain and features such as modeling a sky background, sea background, rain, or snow in the near-infrared region target, were researched. Several static and dynamic simulation models were established, including the driving programs of the simulation. The simulation models are displayed dynamically and approximately. These models were used in the hardware-in-loop experiment for guided bombs.
