基于DOP值的暗室天线组合优选设计

内容简介：基于卫星导航接收机抗干扰测试环境的建设在终端测试中有着至关重要的作用。通过分析建设抗干扰环境的需求,从系统总体和软硬件设计的角度介绍了一种基于导航信号定位精度因子（DOP）的暗室天线组合选择方案。在关键技术分析后给出了系统仿真方案与性能测试方法、结果分析和结论。该方法能够为微波暗室的多发射天线开孔改造以及空分抗干扰接收机测试环境的构建提供一种设计依据。

Abstract：The anti-jamming test environment construction of GNSS SDMA receiver plays an important role in terminal test. Based on analysis of the requirements of anti-jamming environment construction, this paper proposes an anechoic chamber antenna combination selection scheme based on navigation signal position dilution of precision （DOP）. By analyzing the key techniques, it presents system simulation scheme and performance test method, result analysis and conclusion. This scheme can provide a design basis for the reconstruction of muhiple transmit antennas and the construction of SDMA anti-jamming receiver test range.
