Firstly the data of transverse vibration has been processed to eliminate the trend term caused by the trajectory  then obtained the displacement with two times trapezoidal integration. For the side rotation  the high frequency noise interference in the data has been filtered by using five-point moving average method. Took this model as the quivering rule between the object and the image  and then analyzed the effects of the transverse vibration and the side rotation on imaging quality through MTF. By calculation  the r.m.s value of the image motion caused by missile transverse vibration is 0.026mm  and the side rotation angle is 0.0044 . Through the establishment of two modulation transfer functions (MTF) of image random vibration and linear vibration  the results show that the image quality had declined  and the effect of transverse vibration on image quality is obvious. Through improving the rigidity of the missile and selection of small focal length optical system and shorten the time of exposure can improve the imaging quality of the seeker. 2010 IEEE.   On The Interaction Of Channeling/Segmentation Cracks Of Coating: Study On The Critical Spacing 期刊论文  OAI收割 Engineering Fracture Mechanics, 2008, 页码: 2531-2541 作者:  Wu CW(吴臣武);  Chen GN(陈光南);  Zhang K(张坤);  Liang NG(梁乃刚) 收藏  |  浏览/下载：738/74  |  提交时间：2009/08/03 Coating  Channeling/Segmentation Cracks  Critical Spacing  Stress Transfer Length  Thermal Barrier Coatings  Finite-Element-Method  Thin-Films  Stresses  Fracture
