摘要
平面多站无源时差定位系统模型,按到达时间差(TDOA)定位原理建立。由 VC++.Net 编程建立延迟器、TDOA 定位及显示图模块,编译后生成动态连接库并入通信仿真链路。信号源模块产生的时域数据经延迟器延迟,再经相加器输入 TDOA 定位模块,进行时域互相关。求解时差定位估计值后,用定位解最小距离匹配消除定位模糊。
The model of 2D multi-stations TDOA (time difference of arrival) location system is established according to the working principle of TDOA technique. Delay model, TDOA location model and display model is founded with VC++.Net programming, and dynamic link library is created and it is connected to simulation circuit after link library was compiled. The time domain data generated by signal mode was deferred with delayer, the deferred data was sent to TDOA location through adder, time domain data was crossed correlation. The value of TDOA location was estimated, and the fuzzy location was eliminated with least distance matching of locating solution.
