通过理论分析与数值模拟方法，研究了高功率激光系统中非线性热像光强与模糊斑大小的关系。
The relationship between intensity of nonlinear hot image and dimensions of obscurations has been investigated theoretically and numerically.
但SAR图像容易受到相干斑噪声的影响，而光谱图像普遍存在目标与背景对比度差、边缘模糊的缺点。
But SAR image is liable to be affected by speckle noise, while almost spectral image have shortcomings of low contrast between object and background, edge blurring.
同时通过近似计算给出了由于加速间隙电压波动引起束聚焦焦斑模糊范围增大的上限值。
The upper limit values of blurred area coverage of focal spot caused by the fluctuation of accelerating gap voltage are also calculated using a approximate method.
