1.引言用无线电测量设备观测人造卫星位置的方法大致分为:(1)地面站发射电波的应答器法和(2)地面站不发射电波,测量卫星运动产生的多普勒频移的多普勒法(3)测量在几个天线上激励起的电压相位差的无线电干涉仪法。考虑到无线电干涉仪的简单性和良好的测角精度用其观测人造卫星轨道问题,从理论和实验上进行了研究。本文首先论述一种为消除角测量模糊度而研究的的等间距四元无线电干涉仪,并说明为解决十字形配情况下,在卫星轨迹与其中某一天线大致垂直时存在的缺陷。文中就＊字形天线配置的干涉仪论述了其理论研究和实验结果。
1. INTRODUCTION The methods for observing the position of satellites using radio measuring equipment are broadly divided into: (1) the transponder method for transmitting radio waves by ground stations; and (2) the radio waves not radiated by ground stations and the Doppler frequency shift (3) A radio interferometer method of measuring the phase difference of voltages induced on several antennas. Taking into account the simplicity of the radio interferometer and the good angular accuracy of the orbit with its observation orbit, the theoretical and experimental studies. This paper first discusses a kind of equidistant quaternary radio interferometer studied in order to eliminate the ambiguity of angular measurement and shows the defects that exist when the orbit of a satellite is approximately perpendicular to one of the antennas in order to solve the cross configuration. The dissertation discusses the theoretical research and experimental results of the interferometer with the antenna in the shape of *.
