Embodiment Construction

[0008] According to the geodetic coordinate system, the warning area of ​​the radar is divided into 12 sectors according to the azimuth. Establish task library and time resource library for each sector. The sector task library contains the general alert search of the sector and the target tasks of the sector. For conventional search tasks, if there is no prior knowledge (specifically, those are key areas), the tasks are the same, and the time resources consumed are the same. Target tasks are different for each sector.

[0009] Each time resource is the antenna period of the radar divided by the number of sectors. For example, the radar rotates once in 3.6 seconds, and the time resource of each sector is 300ms. By balancing the time resources and tasks of each sector in real time, the time resources of adjacent sectors can be adjusted to the sectors with overloaded tasks, ensuring the high-quality completion of tasks. Specific implementation steps:

Abstract

The invention relates to a rotary phased array radar task load dynamic balancing method. The method is mainly suitable for rotary phased array radar resource scheduling, a warning region is divided into a plurality of sectors according to the orientation, a task library and a time resource library exist in each sector, and task loads in further three sector task libraries are counted at the scheduling moment of the sectors. If tasks in the task libraries are overloaded, sector balancing needs to be carried out. After balancing, when the tasks in the task libraries of certain sectors are executed, the deviation angle of a wave beam can be too large, and the tasks need to be further adjusted. The tasks exceeding the deviation angle of the wave beam are adjusted to the sectors with a small deviation angle. The electric scanning capacity of a rotary phased array is fully utilized, resource balancing of the sectors is achieved, and the quality and efficiency of task completing are greatly improved.

Description

technical field [0001] The invention belongs to the resource scheduling field of rotating phased array radar. Background technique [0002] The two-dimensional rotating phased array radar can realize electrical scanning in azimuth and elevation while mechanically rotating in azimuth, so it has advanced technology, multi-function, multi-task, excellent electronic countermeasure performance, good combat performance, high reliability, High cost performance, good fit, low energy consumption, light weight and other characteristics. The rotating phased array radar adopts an antenna beam with agile capability, which makes the phased array radar extremely flexible in operation. According to the situation of the task load, under the action of the radar controller, the phased array radar can adaptively adjust the working parameters, and switch the beam among various working modes such as search and tracking. Therefore, under certain hardware conditions, it is of great significance t...
