Problems solved by technology

[0004] However, the existing resource scheduling algorithms basically track the entire arc of space targets, resulting in redundancy of most target observation data, which not only causes waste of equipment resources, but also makes space targets with lower priority no resources available
At the same time, when the system handles task conflicts, it cannot automatically adjust the arc time to solve the arc conflict problem. As a result, in the process of making the target plan, the entire arc that directly causes the conflict is discarded, not only failing to complete the planning of the target arc , and equipment resources are not fully utilized

Embodiment 1

[0050] First, the phased array radar resource scheduling process is explained. Specifically, the visibility of the space target relative to the equipment is calculated first, and all visible arcs of the space target that meet the requirements are put into the resource pool as the input element of the resource scheduling algorithm; Then, in the process of planning and scheduling, arc conflict resolution is carried out, and as many visible arcs of various space targets as possible correspond to equipment resources, so as to meet the needs of arc observation and further improve equipment utilization.

[0051] Further, to describe the method for resolving scheduling conflict of phased array radar based on arc segment interception in this embodiment, please refer to Figure 1-Figure 3 , figure 1 It is a schematic diagram of a method for resolving scheduling conflict of phased array radar based on arc segment interception provided by an embodiment of the present invention, figure ...

Embodiment 2

[0107] In this embodiment, the effect of the method for resolving scheduling conflict of phased array radar based on arc segment interception in Embodiment 1 is described through a specific simulation experiment.

[0108] The phased array radar is generally designed with an index m of the maximum number of multiple targets. In this embodiment, the resource utilization rate is used to describe the time utilization of the equipment. The resource utilization rate refers to the difference between the number of planned targets arranged at the same time and the maximum number of multiple targets m. The ratio, the higher the resource utilization rate, the closer the number of target arcs arranged at the same time is to the maximum number of multiple targets m, the more fully the radar equipment is used. This embodiment uses the TLE publicly released on November 7, 2021 as the number of planned targets, and sets a fixed point as the radar equipment position for forecasting and resource...

Abstract

The invention relates to a phased array radar scheduling conflict resolution method based on segmental arc interception. The method comprises the following steps: step 1, obtaining visibility forecast of a space target; 2, carrying out the preprocessing of the visibility prediction, and obtaining a prediction arc section of a space target, which meets the detection conditions of the phased array radar; 3, intercepting the forecast arc section to obtain a target visible arc section meeting a preset orbit calculation condition; and 4, arranging the target visible arc segments according to a preset priority, if an arrangement task conflict occurs, obtaining an idle time interval in the channel according to the arranged target visible arc segments, and arranging the conflicting target visible arc segments according to the idle time interval. According to the method, the visible arc section of the space target is intercepted, the resource utilization rate can be improved to a large extent, the observation requirements of various space targets are further met, and the stable cataloguing number of the space target can be continuously increased.

Description

technical field [0001] The invention belongs to the technical field of space target measurement and control resource scheduling, and in particular relates to a phased array radar scheduling conflict resolution method based on arc segment interception. Background technique [0002] Compared with the rapidly increasing space targets, the resources of phased array radar are still in a state of shortage. For space target measurement and control resource scheduling, domestic and foreign scholars have optimized various resource scheduling strategies for equipment application to improve equipment utilization. [0003] For example, a random search cataloging scheduling algorithm (CB-RSA algorithm) based on the constraint satisfaction problem, which decomposes the scheduling strategy according to the task level and equipment type, and realizes the cataloging of space objects through reasonable scheduling of measurement equipment. The algorithm is fast and stable in the task environme...
