利用MATLAB实现移动目标的TDOA/FDOA定位算法 - CSDN博客
网页无源定位技术是接收站本身不发射信号，而是通过被动接收目标发射或者反射的信号完成定位的一种技术，它被广泛应用于传感器网络、无线通信、麦克风阵列和声纳等领域。 对于静止目标，常见的定位体制是测量目标信号到达各观测站的到达时间差 (Time Difference of Arrival, TDOA)，并计算时差双曲线的交点以估计目标位置。 当目标运动时，可同时利用TDOA和频差（Frequency Difference of Arrival, FDOA）观测量以估计目标位置和速度。
为什么蜂窝无线定位技术不会提到FDOA定位技术 ... - 知乎
网页基于到达频差定位（FDOA，Frequency Difference of Arrival）同AOA、TOA、TDOA一样属于无源定位体制中的一种，由于发射机在移动时会产生与信号频率成比例的多普勒频移，多普勒频差中包含了目标速度信息，可以通过多个接收机的FDOA数据快速获取目标的位置和速 …
Emitter Location Using Frequency Difference of Arrival …
网页2022年12月9日 · Although the FDoA technique is well studied and understood, it is less frequently used as a standalone solution for emitter location than the TDoA or AoA techniques. FDoA-based emitter location, in particular, is highly nonlinear and, therefore, the solution estimation problem is ill-conditioned and sensitive to noise . …
