The mean and covariance matrixes and their inverse matrixes of all eigen vectors are obtained through measured data of the target. And the target is recognized by techniques of range discrimination.

由目标的实测数据，计算特征向量总体的均值和协方差矩阵及其逆矩阵，由距离判别法进行目标识别。

The operating range for extended target is calculated by considering of the target finding ability of eyes, contrast of target luminance, discrimination level and detection probability.

并综合考虑人眼的目标发现能力、目标的亮度对比度、观察等级和探测概率的要求，计算出面源目标的作用距离。

These range from stigmatization to shunning and discrimination against them and their families.
