Embodiment Construction

[0033] refer to figure 1 , the realization steps of the present invention are as follows:

[0034] Step 1. Obtain and sort the requested tasks to obtain a linked list of requested tasks.

[0035] The requested tasks obtained from the task generation module of the phased array radar system are sorted from large to small according to the comprehensive priority, and the requested task linked list is obtained where R iIt is the i-th request task in the request task list, i=1,...,N, N is the request task list The number of requested tasks;

[0036] The comprehensive priority is the request task R i The parameters carried are calculated by the task generation module, which is located at the front end of the functional module of the present invention and is responsible for forming the request task R i , and calculate the request task R i The parameters; the comprehensive priority reflects the importance of the request task, and the sorting enables subsequent operations to pri...

Abstract

The invention discloses a pulse staggered scheduling method in phased array radar resource management to mainly solve the problem that an existing pulse staggered scheduling method is difficultly applied to real-time engineering realization. The pulse staggered scheduling method comprises the first step of ranking request tasks obtained through a task generating module of a phased array radar system according to the comprehensive priority from large to small to obtain a request task chain R, the second step of sequentially traversing the request task chain R in order to carry out bi-directional greedy search scheduling to obtain an executing task chain E, the third step of sequentially traversing the executing task chain E in order to carry out three to five times of secondary scheduling scanning to obtain a final executing task chain E', and the fourth step of sending the final executing task chain E' into a task executing module of the phased array radar system. The pulse staggered scheduling method is high in real-time performance, can be conveniently applied to the engineering realization and can be used for time, energy and resource management of a phased array radar, and the good pulse staggered scheduling performance can be obtained.

Description

technical field [0001] The invention belongs to the technical field of radar, and relates to a pulse interleaved scheduling method for radar task scheduling in phased array radar resource management, which can be used for time energy resource management in phased array radar. Background technique [0002] Phased-array radar has remarkable characteristics such as beam agility, which enables a single radar to simultaneously complete multiple tasks such as search, tracking, and guidance, thus forming a multi-functional phased-array radar system. Under the control of the computer control unit, the multifunctional phased array radar system can adaptively change system parameters such as waveform parameters, so that the radar system can continuously adapt to changes in the external environment and state. However, since the available time and energy resources of the radar system are limited, the multi-functional integration of the radar system must require the radar to reasonably a...
