摘要
GSM基站一般呈蜂窝状分布,从中选取2个GSM基站信号构建的无源雷达系统,这2个基站的相对位置对于探测定位精度有巨大的影响。文中研究了利用应用工程学中风险系数最小原理提高该系统探测定位精度的问题,建立了最优化选择基站的数学模型,通过仿真,验证了方案的可行性,目标10 km时的定位误差小于3 m,对于提高双GSM基站无源雷达系统探测精度具有理论意义和实用价值。
GSM base stations distribute like honeycomb in general,the two GSM base station signals were selected from which for building a passive radar system,the relative deployment positions of the two base stations have enormous influence on the detection precision parameter.This paper studied the application of engineering principles to improve the risk factor to be smallest in positioning accuracy of the system to detect air target.It established the most optimal mathematical model for selection the base stations.Simulations have been done to verify the feasibility of the program.The location precision error is less than 3 m when the target is 10 km away.It＇s of theoretical significance and practical value for improving the detecting accuracy of passive radar system based on dual-GSM base station.
