1.绪论使用人造卫星等飞行体依靠遥测装置观测高空(超高层)的各种现象和物理量时,必须精密地知道得到其测量值时的飞行体的位置。光学观测虽能得到高的精度,但由于受距离、时间和气候限制,所以多采用无线电观测。在进行火箭试验时,虽能利用雷达、应答器等,但现在考虑的是这样一种方法,即地面站处于被动状态,依据接收从人造卫星发射来的甚高频段的信标电波来测量卫星方位。这时角度分辨力大致取决于天线口经对波长之比。但因在甚高频频段,采用无线电干涉仪系统要比用一个大的抛物面容易制成,所以研究了最简单的二振子干涉仪,并与实验结果一起报告如下。 1. INTRODUCTION When flying objects such as satellites rely on telemetry to observe various phenomena and physical quantities at high altitudes (superhighways), the position of the flying object at which their measurements are obtained must be precisely known. Although optical observations can achieve high accuracy, radio observations are often used due to distance, time and climate constraints. While conducting rocket tests, although radar, transponders and the like can be utilized, the method now considered is such that the ground station is in a passive state, measuring satellites on the basis of reception of very high frequency beacon radio waves transmitted from artificial satellites position. At this point the angle of resolution generally depends on the ratio of the antenna port on the wavelength. However, because of the use of a radio interferometer system in a VHF band, which is easier to produce than a large parabola, the simplest two-dipole interferometer was studied and reported together with the experimental results.
