Embodiment Construction
[0027] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but should not be used to limit the scope of the present invention.
[0028] Such as figure 2 As shown, the near-field automatic detection method for dual-band radio frequency equipment in this embodiment includes the following steps:
[0029] S1. Place the full-band horn antenna on the back side of the working antenna and fix it. The horn mouth of the full-band horn antenna is always directed upwards, as shown in image 3 As shown; wherein, the full-band horn antenna covers the Ka frequency band and the Ku frequency band, and the working antenna is a Cassegrain antenna.
[0030] S2. The full-band horn antenna cooperates with the ground analog satellite transponder to transmit and receive short-wave corresponding frequency bands, and in the near-field electromagn...

The invention relates to the technical field of satellite communication equipment operation and maintenance, and particularly discloses a near-field automatic detection method for dual-band radio frequency equipment, which comprises the following steps of: fixing a full-band horn antenna on the rear side of a working antenna, and sending and receiving short waves of a corresponding frequency bandby matching the full-band horn antenna with a ground simulation satellite transponder, comparing the detection data with a tested full-band antenna operation attitude database and ground comprehensiveworkstation operation antenna working parameter data at the same time, and simulating level data obtained by testing the satellite transponder in a single-carrier working state and a forwarding working state through the ground; and judging whether the three-party comparison data is stably kept in a working standard threshold or not so as to finish automatic detection of the servo system in the satellite communication link under a near-field condition. According to the invention, the healthy working state of the servo system can be effectively detected, the detection time is reduced, the operation state of the satellite transponder is accurately and truly simulated, and the ground-air satellite communication joint debugging time is reduced.
Description
technical field [0001] The invention relates to the technical field of operation and maintenance of satellite communication equipment, in particular to a near-field automatic detection method for dual-band radio frequency equipment. Background technique [0002] The ground analog satellite transponder is used to replace the satellite transponder to perform low-noise amplification, filtering and mixing of the uplink signal sent by the ground integrated workstation to generate a downlink signal and send it to the ground user, and simulate the space loss of the uplink and downlink to cooperate with other instruments for system connection. Adjustment test to avoid interference to normal satellite communication services. [0003] As the requirements for satellite communication capabilities continue to increase, the requirements for automatic detection of ground analog satellite transponders also increase. There are essential differences between the near-field test and the far-fi...
