The Performance Analysis and Optimum Design Based on FEM about an Azimuth Reductor Box of Radar Antenna-seat; Alignment and Micro-Displace Measurement with Four-Quadrant Photo-Detector by System Modeling
某型雷达天线座方位减速器箱体有限元分析和优化设计基于系统建模的四像限光电探测器对准与微位移测量系统
The four quadrant impulse correction scheme may lead to the losing of thrust and the increasing of miss distance, since this scheme cannot measure the exact target azimuth information.
