摘要

消隐和对消在许多应用中都能成功地阻挡强干扰，但在超宽带导航领域，很难恢复干扰抵消的效率。本文研究了在装有自主车载速度传感器的有货物的地下矿山中，脉冲干扰环境下的对消效率评估。利用实验得到的干扰环境模型，对匹配的滤波接收机进行了计算机仿真。由于干扰抵消，匹配滤波器输出的信噪比提高了1.9 dB，使其有效地应用于井下矿井超宽带导航。

UWB Signal Receiver Input Cancellation Efficiency in Ranging System with Onboard Speed Sensor

Blanking and cancellation are successfully used to block the powerful interferences in many applications, but in the area of UWB navigation it is difficult to retrieve efficiency of interference cancellation. This research is devoted to the evaluation of cancellation efficiency in conditions of pulse interferences environment in an underground mine with cargos, equipped with autonomous onboard speed sensors. Using the experimentally obtained interference environment model the matched filter receiver is modelled during computer simulation. The signal-to-noise ratio on the matched filter output is increased on 1.9 dB due to the interference cancellation, making the cancellation efficiently applicable in underground mine UWB navigation.
