摘要
为了解决目前目标识别方法应用平台难以实现小体积、低成本的问题,利用线扫描完成激光引信的探测成像,得到了DHGF算法的样本矩阵,建立了基于激光线扫描成像引信的四元评价算法对典型目标的识别模型。该模型使用德尔菲法确定目标轮廓相似度指标集;采用层次分析法确定指标权重分配;运用灰色系统理论确定评价灰类,得到单因素模糊评判矩阵;通过模糊数学理论得出目标识别的评价结果。该算法克服了在小样本数据的情况下,目标识别过程中的模糊性、不确定性等问题,并完成了对典型目标的仿真。仿真结果表明:该算法具备对典型目标的识别能力,可为激光扫描成像引信目标识别提供参考。
Current target recognition method application platform is difficult to achieve small size and low cost,the detection imaging of the laser fuze is obtained by the line scanning. The sample matrix of the DHGF algorithm is obtained,and a quaternary evaluation algorithm based on laser line scanning imaging fuze is established for recognition model of typical target,which uses Delphi method to determine target contour similarity index set. Analytic hierarchy process(AHP) is adopted to determine the index weight distribution,and grey system theory is applied to determine evaluation gray level to get single factor fuzzy evaluation matrix. Fuzzy mathematics theory is applied to evaluate target recognition results. The algorithm overcomes the ambiguity and uncertainty in target recognition process in the case of small sample data. The simulation of a typical target is completed,and the simulation results show that the proposed algorithm has ability to recognize typical targets. The research can provide a reference to laser scanning imaging target recognition.
