基于抗干扰天线的远近效应抑制技术

内容简介：分析了抗远近效应的目标——提高远近距离比,深入地总结了已有的解决方案及其优缺点,然后提出了利用自适应抗干扰天线来抗远近效应的方案,并搭建了半实物仿真平台。最后,通过实验证明这种结合抗干扰天线的方案有效提高了远近距离比,扩大了伪卫星增强系统的覆盖范围。

Abstract：Satellite navigation receivers are designed with regard to the fact that the levels of satellite signals reaching the earth＇s surface are weak and relatively unchanged.This paper firstly describes the concepts relating to the near-far problem and particularly analyzes the objective of near-far effect mitigation aimed at raising near-far ratio,then summarizes in depth the existing solutions and their relative merits,then further proposes a solution to near-far effect mitigation by employing adaptive anti-interference antennae,and finally,through experiment on a hardware-in-the-loop simulation platform established therefor,proves the effectiveness of such solution in raising near-far ratio and enlarging the coverage of pseudolite argumentation system.
