Embodiment Construction

[0015] The present invention uses sectors to allocate radar resources, and the specific implementation steps are:

[0016] 1. Determine the size of the partition ：

[0017] Assume the following parameters of the radar: the beam azimuth size is 1.5°, the data rate of the system is 2-12 seconds, the scheduling interval is 50 seconds, and the antenna rotation is 9° in each scheduling interval. According to the requirement that the maximum data rate of the system is 12 seconds, the size of the partition should be an integer multiple of 6 of the number of azimuths:

[0018] Partition size=1.5 degrees×6×N (N is an integer, to be determined);

[0019] The size of the partition should contain an integer multiple of the scheduling interval:

[0020] Partition size = 9 degrees × M (M is an integer, to be determined);

[0021] The size of the partition should be smaller than the requirements of the 90° sector precision and the target batch number in the scheme:

[0022] Partition si...

Abstract

The invention belongs to the phased array radar resource scheduling field and relates to a sliding window resource scheduling technique based on sectors. The technique is mainly applicable to managing and distributing the resources of two-dimensional rotary phased array radars. A radar system is used for carrying out resource distribution for multiple functions and multiple tasks by sectors, and in each sector, the residence time of tasks of each type is adaptively adjusted according to the capacity of the tasks. The sliding window resource scheduling technique refers to taking the task load conditions within one sector starting from the current scheduling interval into account during resource distribution to the current scheduling interval, and taking the task loads within one sector starting from next interval into account during the next scheduling interval, thereby forming sliding window type resource scheduling. The residence time distribution proportions of the tasks of various types are determined according to different working modes of the radars, and the detection distances of the radars, the search data rate, the fine tracking batch number, the confirmation batch number and the like can be adaptively adjusted according to the time obtained by the tasks, and therefore, multiple functions and multiple tasks are realized simultaneously, and the flexibility and the operational effectiveness of the two-dimensional rotary phased array radars are improved.

Description

technical field [0001] The invention belongs to the field of multifunctional phased array radar resource scheduling, and in particular relates to a resource management and allocation technology in the resource scheduling of a two-dimensional rotating phased array radar. Background technique [0002] Phased array radar resources are flexible and controllable, and different working modes (usually including tracking mode, search mode, etc.) can be switched according to the external environment and needs. The resource allocation ratio of each task is different under different working methods. Reasonable and real-time allocation of radar resources has become an important factor to release the powerful working capacity of the system. [0003] Scholars and engineers at home and abroad have conducted in-depth research on the resource scheduling technology of phased array radar with fixed area array. Representative ones include resource scheduling technology based on knowledge, reso...
