Problems solved by technology
[0003] For the above-mentioned conventional solutions, the multi-base station positioning solution requires information interaction between the device to be positioned and multiple base stations, and the timing of interaction between the device to be positioned and each base station needs to be reasonably scheduled, which increases the interaction complexity and power consumption in the positioning process of the UWB system ; The multiple receiving antennas of the single base station positioning scheme are independent of each other, so each receiving antenna corresponds to a complete receiving front-end channel, which also requires a large power consumption, and in the specific implementation process, the two receiving antennas and The corresponding receiving front-end channels are arranged in the same base station equipment, which increases the complexity and cost of structural design

The embodiment of the invention discloses a positioning method and device based on a multi-transmitting antenna UWB system, equipment and a medium. The method is applied to a to-be-positioned device with a single receiving antenna. The method comprises the following steps: respectively receiving data frames sequentially sent by at least two transmitting antennas of a transmitting terminal device through the receiving antenna; obtaining the distance difference between the at least two transmitting antennas and the receiving antenna according to the sequentially received data frames; and according to the distance between the at least two transmitting antennas, the distance difference between the at least two transmitting antennas and the receiving antenna, and the distance between a reference antenna in the at least two transmitting antennas and the receiving antenna, calculating the position of the to-be-positioned device.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of UWB communications, and in particular, to a positioning method, apparatus, device, and medium based on a multi-transmitting antenna Ultra Wide Band (UWB, Ultra Wide Band) system. Background technique [0002] At present, the conventional solutions for UWB system positioning include multiple base station positioning solutions and single base station positioning solutions. Flight) to measure the distance, and then locate the device to be located based on the distance between the device to be located and the three base stations and the fixed positions of the three base stations. In the single base station positioning scheme, a single multi-receiving antenna base station calculates a phase difference (PDOA, Phase-Difference-Of-Arrival) according to multiple received signals received from a device to be located, and locates the device to be located. [0003] In view of the above conventi...
