摘要
本文给出了一种城市环境下无人机时差定位(TDOA)原理,并分析了无人机TDOA测量值误差的主要来源。从城市环境中无人机信号多径传播的附加时延的统计特性出发,基于统计原理建立了多径效应下TDOA误差的统计模型,并通过仿真进行了模拟试验,验证了TDOA误差统计模型的有效性。
The paper presents a principle of TDOA UAV location under urban environment and analyzes the main sources of TDOA measurement error in TDOA UAV location. Starting from the statistical characteristics of additional delay in multipath propagation of UAV electromagnetic signals under urban environment,a statistical model of TDOA error under multipath effect is established based on principle of statistics. In addition,simulation experiments are carried out to verify the effectiveness of the model.
