基于终端区的多基一次监视雷达布局研究

摘要

对多基一次监视雷达在民航终端区的布局进行研究,以提高主动式监视的精度.监视精度主要由等效距离误差与几何精度因子决定,而对于影响几何精度因子的地面站布局问题,尚缺少研究.为解决以上问题,通过分析定位精度因子及利用到达时间算法,推导出了一种适合终端区的,呈现中心分布式的,发射站与接收站间隔分布的地面站布局形式,并结合解决实际问题的需要,进一步对站点数量、地面站分布重数、地面站发生故障、对地面站分布存在高度差等情况进行了仿真.终端区三维区域内仿真结果表明,所提出布局的水平定位精度满足民航对空管监视要求.%This paper focuses on the distribution of multi-static primary surveillance radar (MSPSR) in civil aviation terminal control area (TMA) to improve the precision level of active surveillance.Combined with the basic concept of the position dilution of precision (PDOP) and the time of arrival (TOA) method,a central symmetrical distribution where the emitting station and the receiving station are in an interval distribution method is derived.On this basis,the effect of different station numbers,different multiple numbers,height difference and the condition of malfunction is analyzed to make the distribution fit practical application.The simulation result state clearly that the horizontal dilution of precision (PDOP) satisfies the civil aviation criteria of surveillance accuracy.
