摘    要:研究设计了航母中线电视监视系统。依据照度、对比度及分辨率要求提出了一套基于电子倍增电荷耦合器件(EMCCD)的光电成像系统。分析了航母中线电视监视系统的舰载稳定平台的精度要求,并探讨了该系统可采用的图像处理算法。分析表明:采用主流的AndorIxonEMCCD并配合口径为40mm的光学系统可满足照度、对比度和分辨率的要求;采用Petzval形式初步设计的F/2光学系统,其光学传递函数接近衍射极限;而现有舰载稳定平台技术可以满足指向稳定的需要。最后,分析了形心算法、边缘算子算法在获取着舰机位置和姿态角的应用。该系统具有全天候工作能力,适用于航空母舰的着舰引导。

关 键 词:航母助降  光电成像系统  综合电视监视  电子倍增电荷耦合器件(EMCCD)

Abstract:A centerline camera subsystem is designed for the mother-ship recovery television surveillance sys- tem. An Electron Multiplying Charge-coupled Device(EMCCD)-based Electrical-Optical(EO) imager is pro- posed according to the requirements for illumination principle, imaging contrast and resolution. The stability of a gyro-stabilized platform and the accuracy of a centerline camera are analyzed, and several imaging processing methods are discussed to solve the problems of position and inclination angles. It is found that the EO system based on Andor Ixon EMCCD with a diameter of 40 mm can fulfill the optical requirements for the centerline camera. The F/2 optical system based on a petzval show its MTF to be close to the diffraction limit. The sta- bility and accuracy status-quo gyro-stabilized platform is enough for the surveillance system. The centroid algo- rithm and edge operator imaging processing method are proposed to calculate the altitude, latitude and inclina- tion. The designed system is capable of performing surveillance with 24-hours a day, which is suitable for air- eraft landing on earriers.
