摘要
针对当前红外探测系统作用距离模型中出现的精度及适用性问题,引入切合实际的波段探测方法,从目标红外辐射、大气衰减及探测系统性能三方面进行建模,并通过迭代算法进行仿真,得到目标辐射强度及探测距离特性曲线。仿真结果显示,目标最大辐射强度及最远距离观察角度均出现在尾后偏离中心处。在对目标全向辐射及探测距离的仿真计算中,得到相似的结论。在与同类文献提供的可靠数据进行比较后,发现该优化模型接近实际情况,可以应用于实际工程。
In view of precision and suitability in current operating range model of infrared detection system, realistic band detecting method was applied, and the model based on infrared radiation of target and atmospheric attenuation and detection system performance was built. Characteristic curves of infrared radiation intensity and operating range were acquired by simulation in iterative algorithm The maximum angle of radiation intensity and the farthest detection range were located near tail and deviating from the central axis, and the similar conclusion was acquired by the simulation of aclinic infrared radiation intensity and operating range. Compared with reliable data of similar paper, the optimizing model is realistic and suitable for engineering application.
