411
- 矩阵中的每一个元素称为像元、像素或图像元素。而g(i, j)代表(i, j)点的灰度值,即亮度值。 由于g (i, j)代表该点图像的光强度(亮度),而光是能量的一种形式,故g (i, j)必须大于零,且为有限值,即: 0<=g (i, j)<2n。 用g (i, j)的数值来表示(i, j)位置点上灰度级值的大小,即只反映了黑白灰度的关系。 数字化采样一般是按正方形点阵取样的, -each of the matrix elements known as a pixel, pixe
high-resolution-one-dimension
- 高分辨率要求系统具有大的带宽,瞬时带宽的增加必将提高系统对硬件的要求,本文采用方便灵活的步进频率波形信号。脉间频率步进波形通过子脉冲载频的步进变化来获得大的有效带宽,使成像具有高分辨率,采用加窗和补零方法提高信噪比,但该信号对目标径向速度非常敏感。采用补零方法提高距离取样分辨率,使距离像细化,并用公式说明了补零只能提高距离取样分辨率,并不能改变频率步进信号的距离分辨能力。该信号波形对目标径向速度的敏感,使目标能量分散到邻近的距离单元造成距离分辨率下降,如果不事先进行速度补偿,直接对回波信号进行逆
