Abstract

The invention discloses a signal sending method and system, a target positioning method, a storage medium and a processor. The signal sending method comprises the step of controlling a base station tosend signals through a plurality of antennas at a preset time slot, wherein the isolation degree between two adjacent signals is greater than a preset isolation degree threshold. A base station is connected with multiple channels of antennas through a switching device, it is ensured that the multiple channels of antennas adopt the same clock source, the function of sending signals by multiple base stations is realized through a single base station and multiple antennas, the technical effect of improving the accuracy of sending signals by multiple antennas is realized, and the technical problems that a unified clock source is needed for multiple base stations to send signals and the positioning accuracy is poor in the prior art are solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a signal sending method and system, a target positioning method, a storage medium, and a processor. Background technique [0002] At present, UWB indoor positioning mainly uses multiple base stations and multiple tags for active or passive positioning. In this process, each base station corresponds to a clock source, and the synchronization accuracy is closely related to the clock source. Once the clock source deviates, it will greatly affect the positioning accuracy of the system. , and the multi-base station deployment has high complexity in the actual deployment process, and the implementation is cumbersome. Multi-base station positioning involves multiple clock sources. It is difficult to precisely control the frequency offset between clock sources of each base station within a reasonable range, and it is more complicated to deploy on site. [0003] For the above problems,...
