Embodiment approach

[0162] In the first embodiment of distance measurement, through the time delay of a single round-trip signal between the device under test 200 and the electronic device 100, the time delay is two times for the electromagnetic wave signal to fly between the device under test 200 and the electronic device 100. Combined with the transmission speed of the electromagnetic wave signal between the device under test 200 and the electronic device 100 , the device under test 200 can measure the distance between the device under test 200 and the electronic device 100 .

[0163] The schematic diagram of signal interaction and time axis in this embodiment is as follows Figure 14 shown. The ranging process will be specifically described below.

[0164] Ranging in this embodiment is based on measurements over a single round-trip message time. Such as Figure 14 As shown, the device under test 200 ( Figure 14 Device A) actively sends data to the electronic device 100 ( Figure 14 In De...

Abstract

The invention provides an angle of arrival determination method and a related device. The method comprises the following steps: acquiring a first phase difference of an antenna signal sent by a to-be-tested device in a first direction; a first arrival angle of the antenna signal in a second direction is determined, and the first direction intersects with the second direction; determining a second angle of arrival of the antenna signal in the first direction according to the first phase difference and the first angle of arrival; and according to the first angle of arrival and the second angle of arrival, determining a target angle of arrival at which the electronic device receives the antenna signal. According to the arrival angle determination method and the related device provided by the invention, the accuracy of arrival angle measurement of the antenna signal can be improved.

Description

technical field [0001] The application belongs to the technical field of angle of arrival measurement, and in particular relates to a method for determining an angle of arrival and a related device. Background technique [0002] The angle of arrival measurement of antenna signals is widely used in the positioning of electronic equipment and remote control of equipment under test. The influence of the angle measurement is also increased, resulting in inaccurate measurement of the angle of arrival of the antenna signal, affecting the positioning accuracy and remote control sensitivity of the device under test. Therefore, how to improve the accuracy of angle-of-arrival measurement of antenna signals has become a technical problem to be solved. Contents of the invention [0003] The present application provides an angle-of-arrival determination method and a related device for improving the accuracy of angle-of-arrival measurement of antenna signals. [0004] In a first aspec...
