本刊2015年第1期刊登了湖南省衡阳市无线电管理处的文章《创新航空干扰三级网格定位法演练机场无线电保障应急预案》之后,多家无线电管理机构的技术人员提出了一个共同的问题:小区4个二级测试点的情况下,如果测向误差偏大的话,其4条实测示向线交会区域很可能会偏离目标实际所在网格,而落入邻近网格。这对目标信号查找工作产生误导。鉴于此,本文结合湖南省衡阳市无线电管理处数据库编制的实际做法,提出一种采用“查表法”的“定点误差”
Article published in 2015 No. 1 Hengyang City, Hunan Radio Management Office of the article “Innovative aviation jamming three grid positioning method of airport radio security emergency response plan,” a number of radio management agencies put forward a common technical staff Problem: In the case of 4 secondary test points in a cell, if the DF error is large, the 4 measured intersections of the measured lines will probably deviate from the grid where the target is actually located and fall into the adjacent grid. This is misleading to find the target signal. In view of this, this article combined with the practice of database management of Hengyang Radio Management Office in Hunan Province, put forward a method of “fixed-point error”
