摘要: 介绍了烟幕的类型和使用方式，分析了喷射式彩色烟幕的遮蔽原理。根据三基色原理提出了采用RGB色彩模式测量评估彩色烟幕色度的方法。分析了目前普遍采用的衰减率数据矩阵插值法测量烟幕形成时间的方法以及该方法在使用中存在的误差因素，提出采用彩色烟幕RGB数据矩阵法测量评估彩色烟幕形成时间的新方法，该方法解决了由烟幕的形状及形成方式、目标的数量及布设方式等因素引起的系统误差，经分析该方法对喷射式烟幕形成时间的测量精度提高到90%以上，具有测量精度高、便于数据处理的优点，丰富了烟幕遮蔽效果测量的评估措施。Abstract: The type and operation of smokescreen were described, the masking principle of jet smokescreen was analyzed .According to the three-primary-color principle, a measurement utilizing red-green-blue (RGB) color mode to assess the chroma of color smokescreen was presented. The attenuation rate data matrix difference method which was currently widely-used to measure the forming time of smokescreen and its errors were analyzed, and a new method using color smokescreen RGB data matrix was proposed to measure the forming time of color smokescreen. The method can eliminate the systematic errors caused by the factors such as the shape and forming way of smokescreen , the target amount, the disposition pattern and so on .Analysis result shows that the measurement accuracy of the method for jet smoke formation time improves 90%, which has the advantages of high accuracy and easy data processing, and provides an effective measure for the smokescreen shielding effect assessment.
