Problems solved by technology

[0005] (1) When driving the carrier detection, the motion state of the carrier (such as heading, roll, and pitch three-axis attitude angle) cannot be quantitatively executed, measured and marked, resulting in inconsistent test conditions for each detection
[0006] (2) When the driving carrier is detected, it often does not cover all the motion states of the carrier (such as the motion state of a ship under high sea conditions), and the detection is incomplete
[0007] (3) Due to the large number of carriers that can be applied to the mobile communication antenna, such as various types of vehicles, ships, aircraft, etc., the motion status and characteristics are different, and the detection method of the driving carrier cannot form a unified standard
[0008] (4) The detection cost of tracking performance of mobile communication antennas based on ships, helicopters, drones, etc. is relatively high

Embodiment Construction

[0041] The present invention will be further described below in conjunction with embodiment.

[0042] An example of ship-borne mobile communication antenna detection:

[0043] (1) Install the mobile Zhongtong antenna on the ship under test on a six-degree-of-freedom swinging platform, and place the six-degree-of-freedom swinging platform in a place where the satellite signal is not blocked.

[0044] (2) Connect the power supply of the on-board dynamic communication antenna, connect the control cable between the on-board dynamic communication antenna and the upper computer, and connect the downlink signal (LNB output) of the on-board dynamic communication antenna to the signal input port of the spectrum analyzer.

[0045] (3) Connect the data processing host computer with the LAN port of the spectrum analyzer;

[0046] (4) The six-degree-of-freedom oscillating table starts, runs to the zero position of the six-degree-of-freedom, and stops.

[0047] (5) Set spectrum analyzer p...

Abstract

The invention relates to a communication-in-moving antenna tracking performance detecting method based on a six-freedom-degree swinging table and belongs to the field of communication-in-moving antenna detecting field. A system used in the method comprises the six-freedom-degree swinging table, a spectrometer and a data processing upper computer. A tested communication-in-moving antenna is arranged on the six-freedom-degree swinging table. Down-going signals (output by an LNB) of the communication-in-moving antenna are connected with the spectrometer through a coaxial electric cable. The data processing upper computer is connected with the spectrometer through an LAN interface. According to the method, the detecting standard is unified, detecting is comprehensive, accuracy is high, and universality is high.

Description

technical field [0001] The invention relates to a method for detecting the tracking performance of an antenna in motion based on a six-degree-of-freedom sway platform, and belongs to the field of antenna testing in motion. Background technique [0002] Mobile satellite communication antenna refers to a satellite communication antenna that isolates the movement of its installation carrier through its own servo control system, and controls its satellite communication port antenna to track and align geostationary satellites in real time to establish a satellite communication link. Antenna". The mobile communication antenna can be installed on various carriers such as vehicles, ships, drones, and helicopters, and it has the performance of real-time tracking and alignment of satellites in geostationary orbit (referred to as "tracking performance"). [0003] At present, the detection of the tracking performance of the domestic mobile communication antenna is to install the mobile...
