舰载烟幕弹遮蔽效能的仿真研究

施放烟幕是对抗光电制导武器的重要手段,而烟幕遮蔽性能是烟幕弹的一个最主要的测试指标。烟幕的遮蔽干扰效果可以通过数学模型加以计算和预计,本文在建立烟幕透过率、烟幕遮蔽面积测量仿真模型的基础上,通过计算机仿真对烟幕遮蔽效能进行了分析,并根据仿真结果得出了烟幕遮蔽面积、透过率随时间变化的一般规律。

Simulation Study of Masking Efficiency of Shipboard Smoke Shell

Smoke screen discharging is an important way to confront optoelecronic guided weapons and the disturbing effectiveness of a smoke screen is the most important test specification of a smoke shell. The disturbing effectiveness of a smoke screen can be calculated and predicted by using a mathematic model.In this paper,a simulation model for measuring the transmittance and effective disturbing area of a smoke screen is established.The disturbing effectiveness of the smoke screen is analyzed through the simulation by a computer.Finally,the common rule of the disturbing area and transmittance of the smoke screen varied with time is obtained according to the simulation result.
