引言一部新的锁相干涉仪跟踪系统现已在西德中心地面站(Lichtenau-Weilheim)安装完毕,由西德联邦技术研究部主管。干涉仪系统由三部可控天线及其相应的信道接收设备和中心计算机组成。天线设置在南北和东西方向相等的直角等腰三角形的角上,中心站的基准点位于斜边的中点。干涉仪方块图如图1所示。图2示出宇宙飞行器位置与要测的二天线间相差间的基本相位关系。单脉冲跟踪天线完成模糊度值i的分辨。
Introduction A new phase-locked interferometry tracking system is now installed at the Lichtenau-Weilheim site, headed by the Federal Ministry of Technology Research. The interferometer system consists of three controllable antennas and their corresponding channel receiving equipment and a central computer. Antenna set in the north-south and east-west equal right angle isosceles triangle angle, the center of the reference point in the hypotenuse of the midpoint. Interferometer block diagram shown in Figure 1. Figure 2 shows the basic phase relationship between the position of the space vehicle and the phase difference between the two antennas to be measured. Single pulse tracking antenna to complete the ambiguity value i resolution.
