摘要
在典型环境条件下的烟幕外场试验中,利用多波段成像传感器对野外施放烟幕条件下的运动目标进行测量,得到烟幕透过率、消光效果,利用成像跟踪器的实时跟踪误差确定指定类型烟幕的干扰效能;在试验中烟幕采用某型发烟源施放,成像探测波段包括可见光、红外长波和红外中波,透过率绝对值测量使用激光器和功率计探测;通过试验得到跟踪窗口为320~240,帧频为25Hz的动态烟幕条件下目标30s跟踪图像及其脱靶量变化数据;根据对得到的试验结果进行分析归纳,为该类型的烟幕使用以及成像跟踪对烟幕干扰的对抗提供了可靠的依据。
In the smoke field test with representative conditions, the moving targets can be measured by multi--speculum imaging sensors through the smoke. The smoke disturbance can be concluded with the results of smoke permeate ratio and extinction effect also with the tracking progress of imaging sensors. The smoke in the field test was loaded by smoke cans, and the imaging sensors speculum include visible light, far infrared and middle infrared. The laser can test the smoke permeate ratio and extinction absolute value. Data of the 30seconds imaging tracking progress with window of 320-240 and speed at 25Hz was present during the field testing. With those data gotten in the smoke test, it provide the key rules of this type smoke in the field of smoke disturbance performance and imaging sensors electro--optic encounter.
