Method for improving the beam - steering accuracy of phased array antenna 提高相控阵天线波束指向精度的方法
Along with the development of the aerospace technology , the next generation of spacecraft will have an unprecedented degree of autonomy and pointing accuracy 随着航天技术的发展,新一代航天器将具有空前的自主能力和指向精度。
Finally , attitude stabilization control of the satellite and pointing precision of the payload are researched in the phase of infrared camera tracking object 第三,在红外相机跟踪目标阶段,研究了星本体的姿态稳定控制以及有效载荷的指向精度问题。
For ka - band communication antenna , several classes of different satellite weight were considered and the critic first frequency of antenna system was given 为满足ka频段通讯天线的指向精度指标,文中针对不同质量的卫星平台,计算了对天线系统的最小刚度要求。
