摘要:

广播式自动相关监视(ADS-B)作为新一代空中交通管制监视系统存在位置报告信息真伪判决问题。本文提出基于单脉冲测角技术的解决方案，并针对单脉冲测角可用线性区间尺度的影响因素进行研究。理论分析和仿真实验结果表明，噪声水平、加权方式、波束指向和阵元个数均对单脉冲可用线性区间尺度产生影响，合理配置系统参数可以实现单脉冲测角线性区间尺度的优化，提高测角精确度。

Abstract:

There exist some authenticity judgment problems in position reporting in Automatic Dependent Surveillance-Broadcast(ADS-B) which is the next generation of air traffic control surveillance system. A solution based on monopulse angle measuring technology is proposed，and the influence factors on the available linear interval dimension of monopulse angle measurement are studied. Theoretical analysis and simulation experiments prove that the noise level，weighting method，beam direction and the number of array elements are all the disturbance factors to the monopulse available linear interval dimension. Therefore, configuring system parameters properly would be helpful to optimize the whole linear interval dimension and to improve the precision of angle measurement.
