摘要
从三站对辐射源联合时差定位的原理入手 ,总结出基于时差误差与站址误差分离的定位精度模型 ,估计了目标高度引起的平面位置定位误差范围 ,通过计算机仿真得出了关于定位误差分布和布站选择的有益结论 ,最后给出了定位精度推算模型 .
We have investigated a location precision model based on the separated error of TDOA from that of station site by analyzing the principle of tri-station united TDOA location towards emitters.The scale of 2-D location error caused by target height is estimated as well.With the help of computer simulation,we have made some useful conclusions about the distribution of location error and station deployment.Then a location precision reckoning model is proposed.
