Embodiment Construction

[0015] The service system concept of task scheduling includes the following eight contents.

[0016] 1. Customer: Radar mission.

[0017] 2. Service Desk: Scheduler.

[0018] 3. Queuing rules: queue from high priority to low priority.

[0019] 4. Service rules: service with priority (Priority, PR).

[0020] 5. Captain L s : The number of radar tasks in the service system.

[0021] 6. Queue leader L q : The number of radar tasks queued in the system.

[0022] 7. Stay time W s : The dwell time of a radar task in the system.

[0023] 8. Waiting time W q : The amount of time a radar task is queued for execution.

[0024] The process of the present invention is as follows.

[0025] Step1 obtains the distribution model of passive radar tasks by analyzing the prior knowledge of a large number of passive radar tasks, assumes that the radar task flow approximates Poisson flow, calculates the average arrival rate λ of radar tasks, the average service rate u of tasks, and calcu...

Abstract

The invention discloses a passive phased array radar resource dynamic queuing management and control method. The method comprises the following steps: regarding radar mission arrival and execution as a 'client queuing service' process and obtaining the service system parameters, such as the mission queuing average length and the average waiting time, by analyzing the priori knowledge of a plenty of passive radar missions; computing the integrated priority of the missions and generating a queue based on the characteristic parameters, such as the mission deadlines, the working mode priority, the residence time and the expected execution time; dynamically matching the missions with radar system resources; computing the service effective rate in real time. The method can achieve the effects of effectively utilizing the passive radar resources and improving the operational efficiency, computing the knowledge-based system service parameters and the integrated priority of the missions, ensuring effective execution of the missions, matching the missions and the resources in real time, increasing the resource utilization rate, computing the system service effective rate and assessing the service results in real time. The method can support enhancement of the passive radar resource management and control capacity and can be popularized in the field of radar resource scheduling.

Description

technical field [0001] The invention relates to the field of passive phased array radar resource management and scheduling, and mainly relates to passive resource scheduling service system parameter design, task priority sorting, radar task-resource optimization matching strategy and the like. [0002] technical background [0003] Advanced and effective resource scheduling management technology is the key to the best performance of passive radar. Passive phased array radar resource scheduling is tightly hinged with subsystems such as signal processing, data processing, and terminal display and control, and various parameters are optimally configured to make full use of radar time, computer and other resources to better play the performance of passive radar. Passive phased array radar resource scheduling requires fast task execution, less task delay, low resource usage, and high probability of interception. Designing a reasonable and optimized resource scheduling plan is the ...
