烟幕的湍流效应对热成像制导导弹性能的影响

Effect of Smoke Scren Wobble on Ir Imaging Guided Missile Performation

在热成像系统静态模型的基础上,利用运动传递函数分析了烟幕湍流效应随成像制导导弹性能的影响,建立了动态性能理论模型,利用计算机对动态性能模型仿真,仿真结果表明湍流效应对制导导弹性能的影响是明显的。

Based on IR imaging system static performance model, the effect of smoke screen wobble on the system performance was theoretically analyzed with the motion transfer function. Additionally, detection criteria by background clutter was introduced, and dynamic performance model was established and simulated. The modeling result shows that the influence of smoke screen wobble on the system field performance should not be ignored.
