Embodiment Construction

[0014] In order to meet the use requirements of the new generation of satellites, the power consumption of satellites has climbed to tens of thousands of watts, and the satellites are equipped with multiple deployable antennas and various electronic equipment and components, which brings potential radio frequency interference and radiation coupling problems. . Although the radio frequency compatibility problem can be reduced to a certain extent through the radio frequency compatibility prediction analysis design, in order to verify the results of the radio frequency compatibility prediction analysis and design of the equipment, it is still necessary to carry out the radio frequency compatibility test, which is subject to various antenna structures. Due to constraints such as layout and ground deployment tests, the problem of deploying all antennas to form a real working state on orbit for radio frequency compatibility tests has become a sharp contradiction, which limits the dem...

Abstract

The invention provides a method for compatibility test on fully-unfolded RF,which comprises the following methods: step 1, ensure the antenna layouts and signal characteristics of various RF transceiver links on stars; step 2, reasonably design RF compatibility test status; step 3, experiment verification, arrange test group status through simulating flight phase of on-orbit satellite, with focus on RF compatibility test toward links with close positions and similar frequency bands, as well as the RF compatibility test toward RF of unfolded double-dimension scanning antenna in the wicked operating status, and modify its adaptability on stars according to experiment result to ensure the whole-star compatibility test. The test method not only solves the compatibility test problem of such multi-antenna fully-unfolded RF, but also largely improves the efficiency through reducing test statuses.

Description

technical field [0001] The invention relates to a satellite radio frequency compatibility test method, in particular to a fully expanded radio frequency compatibility test method. Background technique [0002] In order to meet the use requirements of the new generation of satellites, the power consumption of the satellites has climbed to tens of thousands of watts. The satellites are equipped with large-scale deployable Synthetic Aperture Radar (SAR) planar phased array antennas, spot beam two-dimensional tracking deployable relay antennas, and spot beam two-dimensional tracking antennas. Dimensional tracking and deployment data transmission antennas, nine fixed measurement and control antennas, two navigation fixed navigation receiving antennas, and various electronic equipment and components, all of which have potential radio frequency interference and radiation coupling problems. Although the radio frequency compatibility problem can be reduced to a certain extent through...
