Description
Technical Field
The application relates to the technical field of aerospace measurement and control network management, in particular to a resource scheduling method, device and computer equipment for antenna array demand.
Background
In deep space measurement and control, the transmission attenuation of communication signals is large due to the very large distance between the spacecraft and the ground station, and how the ground station receives weak signals transmitted back from remote space is an important problem. Increasing the antenna aperture of a ground station is an effective means for improving the system's reception of weak signals, but since the design of the maximum antenna aperture is already approaching a limit, antenna array techniques that synthesize signals from multiple antennas are effective means for improving the signal-to-noise ratio of the signals. The antenna array technology is to utilize a plurality of reliable, relatively high cost performance and variable scale small-caliber antennas to form an antenna array, receive the same signal, and utilize the coherence of the signal and the uncorrelation of the noise to weight and synthesize the signals received by each antenna so as to obtain the required high signal-to-noise ratio received signal. This technique is characterized by flexibility in that the antenna array can serve several tasks simultaneously and can provide a caliber that meets the requirements of each task. Meanwhile, compared with a large antenna, the small antenna has a longer life cycle, higher cost performance and much lower maintenance difficulty and cost.

In the actual use process, the deep space antennas can work independently and can work in an array mode, the array antennas and the single antennas can operate simultaneously, the functions of the antennas are different, and the modes of participating in tasks are various. The common general scheduling object of the space measurement and control network resource scheduling algorithm is for a single antenna, and the individual algorithm can be suitable for a multi-beam antenna without direct use, so how to adapt to the antenna array demand is an important problem to be solved by the space measurement and control network resource scheduling.

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
In one embodiment, as shown in fig. 1, a resource scheduling method facing antenna array requirements is provided, which includes the following steps:
step 102, performing equipment identification on the resource use application with the group array requirement according to the group array requirement of the user, the selectable antenna identification and the number of antennas required by the group array.
The resource use application is sent to the deep space measurement and control network management center by the operation control center of the deep space detector, the operation control center is a user, and the deep space measurement and control network management center is responsible for scheduling the deep space measurement and control equipment to meet the resource use requirements of the user. The deep space measurement and control equipment is deployed at a deep space measurement and control station, and in general, a measurement and control network formed by a plurality of deep space measurement and control stations on the ground is called a deep space network or a deep space measurement and control network, in particular to a special measurement and control network special for measurement and control and data transmission of a deep space spacecraft.
