Abstract

The invention discloses a precise distance measuring device based on UWB. The UWB signal adjustment module includes a signal differential coupling unit, a first microwave switch unit, a radio frequency power amplifying unit and a second microwave switch unit. The signal differential coupling unit and The first microwave switch unit is bidirectionally connected, the output end of the first microwave switch unit is electrically connected to the input end of the radio frequency power amplifying unit, and the output end of the radio frequency power amplifying unit is electrically connected to the input end of the second microwave switch unit. The invention has the advantages of simple and compact structure, low cost, can realize distance measurement based on UWB, has high distance measurement precision and wide measurement range.

Description

technical field [0001] The invention relates to the technical field, in particular to a UWB-based precise ranging device. Background technique [0002] With the rapid increase of data services and multimedia services, people's demand for positioning and navigation is increasing, especially in complex indoor environments, such as airport halls, exhibition halls, warehouses, supermarkets, libraries, underground parking lots and mines, etc. It is often necessary to determine the location information of the mobile terminal or its holder, facilities and objects indoors. At present, positioning and ranging mainly include ultrasonic ranging technology, Bluetooth ranging technology, radio frequency identification ranging technology, Wi-Fi ranging technology, etc., but each positioning and ranging method has certain limitations. Multipath effects and non-line-of-sight propagation have a great impact, and at the same time require a large amount of investment in underlying hardware fa...
