摘要 利用外场试验数据确定了三角形方向鉴别阈值准则.基于坦克目标和三角形靶标的外场测量图像,利用必选决策分别统计了不同距离处的坦克目标和三角形靶标的鉴别概率;采用Weibull函数最小二乘方差拟合鉴别概率数据,确定了75%正确判断概率对应的三角形方向鉴别阈值准则.与约翰逊准则及国外提供的三角形方向鉴别阈值准则比较可知,基于所做试验数据估计的三角形方向鉴别阈值准则是合理的. Triangle orientation discrimination threshold （TOD） criteria are determined utilizing the field experimental data. The discrimination probability of the tank and triangle pattern in various ranges is given by the statistical method, respectively using the forced-choice experimental method based on their field measured image. Further, the Weibull function is fitted to the discrimination probability data by the least-square deviation method, and the TOD criteria corresponding to 75% correct discrimination probability are determined. A comparison with John＇s criteria and TOD criteria provided by TNO shows that this method can determine a reasonable evaluation value for the TOD criteria.
