| 摘 要： | 从红外辐射理论和热成像仪工作原理出发,得到了烟幕类干扰剂对热成像系统遮蔽效果的定量测试方法以及相应计算公式.该方法基于辐射亮度的相对测量,无需黑体,直接以面源型被遮蔽目标为靶标,简易快速,既能直观可视地评价遮蔽效果,也可以定量表征遮蔽率.外场试验结果表明,该测试方法所得定性与定量结果一致性较好.

| Abstract: | Based on laws of infrared radiation and working characteristics of the thermal imager,a quantitative measuring method and the operational formula of screening efficiency of infrared screening materials are presented in detail.Relative measuring of equivalent radiation brightness is employed in this method,and a screened facial object instead of blackbody is used as a target,which can make the test easy and quick.We can directly observe the screening effect and quantitatively measure the screening efficiency... |
