英文: Abstract: The threshold algorithm of the target detection is often used to detect target echo signals.Its performance is based on signals-noise ratio.When signals-noise ratio is great than 6.7,the target can be detected.In order to increase the signals-no
中文: 文摘:目标检测的阈值法经常用于检测目标的回波信号.它的性能取决于信噪比,当信噪比大于6.7时,能够检测出目标.为了提高信噪比,经常采用匹配滤波器.如果系统是窄带系统,噪声为色噪声,无法使用匹配滤波器,不能提高信噪比.激光回波信号的几何特征不同于噪声.提出了一种利用这种几何特征检测目标的算法.当信噪比大于2时,该算法能够检测出目标.该算法已经实际应用.

英文: Additionally, target detection will take into account a target's radar cross section (RCS), its aspect angle, and its air speed (targets below the threshold gate will not be detected).
中文: 外加目标的确定怎加了计算目标的RCS值当空速低于这个门限的时候目标将无法被察觉.
