Abstract

The disclosure provides a direction finding method, which comprises the steps: determining a plurality of incident angles, being included angles of the signal relative to a vertical line of a connecting line of two antenna units in the antenna array, of a signal sent by a target relative to an antenna array; and determining the direction of the target according to the incident angles and first weights corresponding to the incident angles. The first weights corresponding to the incident angles are in negative correlation with the absolute values of the incident angles. With the direction finding method provided by the invention, the direction finding precision of target direction finding can be improved.

Description

technical field [0001] The present disclosure relates to the field of Internet of Things, and in particular, to a direction finding method and device, and an ultra-wideband direction finding system. Background technique [0002] With the development of the Internet of Things, location information is becoming more and more important, and there is an increasing demand for high-precision location information. At present, there is a problem of low precision in the measurement of direction information. [0003] Therefore, how to improve the direction finding accuracy when performing direction finding on the target becomes a technical problem that needs to be solved by those skilled in the art. SUMMARY OF THE INVENTION [0004] An embodiment of the present disclosure provides a direction finding method, which includes: determining multiple incident angles of a signal sent by a target relative to an antenna array, wherein the incident angle is the signal relative to a connection...
