Embodiment Construction

[0048] The present invention will be further described below in conjunction with accompanying drawing:

[0049] refer to figure 1 , is a schematic flowchart of the prior knowledge-based phased array radar adaptive task scheduling method of the present invention. The prior knowledge-based phased array radar adaptive task scheduling method includes the following steps:

[0050] S1: According to the priority of the radar task, establish a corresponding radar classification task list, each radar classification task list includes radar tasks with the same priority; select n / 2 radar classification tasks in order of priority from high to low linked list, n is the number of radar classification task linked lists; in the selected n / 2 radar classified task linked lists, if the time window of each radar task is greater than the scheduling interval of the phased array radar, then execute step S2, otherwise , execute step S3. The specific instructions are as follows:

[0051] Step S1 s...

Abstract

The invention belongs to the technical field of phase array radar task scheduling and particularly relates to a priori knowledge based phase array radar self-adaption task scheduling method. The priori knowledge based phase array radar self-adaption task scheduling method includes steps of S1, establishing a radar classified task chain list; selecting n / 2 radar classified task chain lists according to the high-to-low sequence of priority; implementing a step S2 if time window of each radar task in the selected n / 2 radar classified task chain list is longer than scheduling interval of a phase array radar; S2, obtaining a scheduling sequence of each radar task based on time minimum loss principle; S3, establishing a novel radar classified task chain list according to the two radar classified task chain lists with highest priority; scheduling each radar classified task chain list according to the high-to-low sequence of the priority until each radar task in each radar classified task chain list is scheduled.

Description

technical field [0001] The invention belongs to the technical field of phased array radar task scheduling, in particular to a phased array radar adaptive task scheduling method based on prior knowledge, which solves the problem of low task execution efficiency under limited radar system resources, and can be based on the radar scheduling The prior knowledge of the interval and each task time window is used for effective adaptive task scheduling to improve the execution efficiency of tasks. Background technique [0002] The beam of the phased array radar can point to any direction in space and can be agile at the level of microseconds to hundreds of microseconds. In addition, the phased array radar also has rich working waveforms, variable parameter control, optional Various working modes and powerful data processing capabilities enable phased array radars to simultaneously realize functions such as surveillance, detection, tracking, identification, and weapon guidance, with ...
