对多基一次监视雷达几何精度因子进行了研究。根据民航航路和终端区域的监视需求,提出了采用多个发射站和多个接收站的多基一次监视雷达结构,并根据基于到达时间(TOA)的定位方法推导了最小均方误差位置估计算法和几何精度因子。最后用MATLAB仿真分析了采用不同的地面站布局来改善水平精度因子。仿真结果表明采用多个发射站和接收站结构的多基一次监视雷达能满足民航航路和终端区的监视精度要求。
The geometric accuracy factor of multi-base once-monitoring radar was studied. Based on the monitoring requirements of civil aviation routes and terminal areas, a multi-base primary surveillance radar structure using multiple transmitting stations and multiple receiving stations is proposed. Based on the arrival time (TOA) method, a minimum mean square error location estimation algorithm And geometric accuracy factor. Finally, MATLAB simulation analysis of the use of different ground station layout to improve the level of accuracy factor. The simulation results show that the multi-base primary surveillance radar with multiple transmitting and receiving stations can meet the monitoring accuracy requirements of civil aviation routes and terminal areas.
