Abstract

Orthogonally linearly polarized radio-beacon signals are emitted simultaneously from two spatially separated points in the horizontal plane to determine the bearing and roll angles. The resulting vector signals from the radio beacon are received by a receiving antenna on board an aircraft. The antenna irradiator is equipped with a polarizing modulator in the form of a ferrite rotator of the polarization plane. The bearing and roll angles are estimated at the receiver output at a frequency that is a multiple of the polarization-modulation frequency of the received beacon signals. The layout of the apparatus that performs this method is described. The results of measuring the navigation elements are presented. The mean square errors of the bearing and roll angle measurements were 0.48° and 0.35°, respectively.

通过正交线性极化信标信号确定飞机方位角和侧倾角的方法

摘要

从水平面中两个空间上分离的点同时发射正交线性极化的无线电信标信号，以确定方位角和侧倾角。来自无线电信标的合成矢量信号由飞机上的接收天线接收。天线辐射器配备有极化平面铁氧体转子形式的极化调制器。在接收器输出处以为所接收信标信号的偏振调制频率的倍数的频率来估计方位角和侧倾角。描述了执行该方法的设备的布局。给出了导航元素的测量结果。轴承和侧倾角测量的均方误差分别为0.48°和0.35°。
