| 1. | The software will display the snr , fwhm and rms values found
软件将显示它们的信噪比，点扩展函数和均方差值。 |
| 2. | Restoring turbulence - degraded images based on estimation of turbulence point spread function values
基于估计点扩展函数值的湍流退化图像复原 |
| 3. | Generally , an aperture radius of two to three times the fwhm of the psf is a good value
一般的，孔半径设置为点扩展函数的半宽值的两到三倍比较好。 |
| 4. | In other words , this value sets a limit on how much a real detection may differ from the assumed psf
意思是，对于不同的模拟点扩展函数究竟什么的目标才能被判断为真实目标，本值提供了一个限制值。 |
| 5. | Psf - fit rms : the maximum rms for the difference between the model psf and the actually fitted profile
点扩展函数的适合均方根：对于模拟点扩展函数与真实的适合的剖面图之间的不同，软件所使用的均方根的最大值。 |
| 6. | Choose a size large enough that the peak of the psf of the stars will be within the aperture , but small enough to resolve close pairs of stars
设置足够大的值，从而可以使恒星的点扩展函数范围在此半径之内，单也要小到足以区分密近双星。 |
| 7. | Because of the equivalence of spotlight sar and rotating target imaging , the impsar pro jection reconstruction theory can be successfully used in spotlight impsar
本文利用点扩展函数推导了旋转目标成像在360和小角度时的分辨率解析表示。 |
| 8. | Different from the other kinds of uwb signal , the radiation and picking up of the impulse signal has a very special property , time and space coupling
结果表明impsarwb - p算法方位分辨率与利用点扩展函数( psf )的分析结果基本一致，这也从另一方面证明了wb - p算法的有效性。 |
| 9. | Some different specific arithmetic were presented in recent 20 yrs . but all these arithmetic are applicable to point spread function which the parameters are known
目前，对于不同原因造成的图像变质的复原有了深入的研究，到现在已经提出了不同的具体算法，但这些方法适用于点扩展函数并已知其参数的情况。 |
| 10. | When the bar code is of higher density , adjacent edges interact each other due to the influence of the point spread function of image collection system , therefore , this kind of method becomes invalid
当条码密度较大时，受光学系统点扩展函数的影响，边缘相互干扰，这种技术不再适用。本文研究了高密度二维条码的识别技术。 |
