The elevate-azimuth structured seeker has been studied for a long time  and it is applied in all sort of missiles. Not only structure design but also control algorithm of the elevate-azimuth seeker are deeply developed. But for elevate-azimuth seeker there are several disadvantages such as big size and large abaxial angle blind. So the elevate-azimuth seeker gimbal angle is designed up to 65 according to relative references. In modern air war  it is important for a missile to have the ability of "first recognize" and "first attack". That means the air to air missile seeker is required to be a system with large gimbal angle and large abaxial launch angle. With the mentioned requirement  roll-pitch seeker with its advantages smart size and large gimbal angle is studied widely and deeply. The pitch angle of roll-pitch is up to 90 while its roll angle up to n 360. But there are also some disadvantages for the roll-pitch seeker  the most troublesome one is the zenith pass problem. The zenith pass problem is brought about from the gimbal kinematics  it is said that when target moves in the center of image plane  roll servo command gotten from the kinematics algorithm will go to infinite. Math model of zenith pass problem is proposed in this paper and two ways to solve the problem are brought forward. 2011 IEEE.   Estimation of canopy gap size and gap shape using a hemispherical photograph 期刊论文  OAI收割 TREES-STRUCTURE AND FUNCTION, 2009, 卷号: 23, 期号: 5, 页码: 1101-1108 作者:  Hu, LL;  Gong, ZW;  Li, JS;  Zhu, JJ;  Zhu, JJ, Chinese Acad Sci, Inst Appl Ecol, Wenhua Rd 72, Shenyang 110016, Peoples R China   |  收藏  |  浏览/下载：25/0  |  提交时间：2011/09/23 Forest Gap  Fisheye Lens  Shape Index  Zenith Angle  Gap Size
