Problems solved by technology

The existing antenna TIS (Total Isotropic Sensitivity, Total Isotropic Sensitivity) evaluation method is mainly used to evaluate the receiving performance of isotropic antennas (that is, omnidirectional antennas). However, with the rapid development of the communication field, directional antennas It has been gradually applied in satellite communications and some directional communications. Due to the strong directivity of the antenna direction of the directional antenna, the existing antenna TIS evaluation method is no longer suitable for evaluating the receiving performance of the directional antenna.

Embodiment 1

[0048] see figure 1 The flow chart of a receiving performance evaluation method of a directional antenna shown includes the following steps:

[0049] Step S102, detecting sensitivity test values ​​of the directional antenna to be tested at each test position; the azimuth angle and / or inclination angle of different test positions are different.

[0050] The anechoic turntable in the OTA test system can move the directional antenna to different Theta angles (ie tilt angles) and Phi angles (ie azimuth angles) in sequence. The azimuth angles and / or tilt angles of different test positions are different. All locations need to measure the sensitivity test value of the directional antenna, and record the results. For example, when testing a directional antenna, it is assumed that the Theta angle is set from 0 degrees to 180 degrees, and each 30 degrees is a step length of 6 steps; the Phi angle is from 0 degrees to 360 degrees, and each 30 degrees is a step length. , a total of 12 s...

Abstract

The invention provides the receiving performance assessment method and device of a directional antenna and relates to the communication technology field. The method comprises the following steps of detecting the sensitivity test value of the directional antenna to be tested at each test position, wherein the azimuth angles and / or angles of inclination at different test positions are different; searching weight corresponding to each test position; and according to each test position, the sensitivity test value corresponding to each test position and the weight, assessing the receiving performance of the directional antenna. In the invention, the receiving performance of the directional antenna can be reasonably and reliably assessed.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for evaluating the receiving performance of a directional antenna. Background technique [0002] In order to ensure the reliability of the antenna and to apply the antenna reasonably to the market, it is necessary to evaluate the reception performance of the antenna. The existing antenna TIS (Total Isotropic Sensitivity, Total Isotropic Sensitivity) evaluation method is mainly used to evaluate the receiving performance of isotropic antennas (that is, omnidirectional antennas). However, with the rapid development of the communication field, directional antennas It has been gradually applied to satellite communications and some directional communications. Due to the strong directivity of the antenna direction of the directional antenna, the existing antenna TIS evaluation method is no longer suitable for evaluating the receiving performance of the directi...
