摘要

本文描述了来自下伏地表的脉冲无线电信号反射的数学模型，并给出了该模型在喇叭天线和维瓦尔第单元天线阵列振幅测向仪精度估计中的实际应用结果。结果表明，利用所提出的地表反射多点模型，可以分析接收到的脉冲信号的畸变，并估计单脉冲幅度测向仪在不同长度的无线电波传播表面轨迹上的射电发射源测向误差。

A Model of Reflections of Pulsed Radio Signals from the Earth's Surface and Its Practical Use in Assessing the Accuracy of Amplitude Directional Finders

The description of a mathematical model of reflections of pulse radio signals from the underlying Earth's surface and results of its practical use for estimation of accuracy of amplitude direction finders with horn antennas and antenna arrays of Vivaldi elements are presented. It is shown that the use of the proposed multipoint model of reflections from the ground surface allows an analysis of distortions of received pulse signals and estimation of errors of direction finding of radio emission sources by a monopulse amplitude direction finder on surface traces of radio wave propagation of different lengths.
