Embodiment Construction

[0035] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0036] Phased array radar has the characteristic of working with wave standing (CPI) as the beat in time. CPI is the indivisible minimum time unit for the normal operation of the radar. Therefore, resource scheduling with wave standing as the beat is the optimal resource for radar. An inevitable choice for scheduling. Therefore, in the resource scheduling method of the present invention, the radar resource scheduling is performed by the radar scheduling module according to the wave standing as the beat and driven by the wave standing events. The scheduling module takes the SYN as the beat and the SYN event as the driving source, and dynamically updates the event queue according to the data report of the signal processor or the combat mission requirements, and always executes the event with the highest priority first. With dynamic beam dwell time, events are seam...

Abstract

The invention relates to a phased array radar self-adaptive resource scheduling method based on a wave parking rhythm and event driving. Resources such as phased array radar time and energy are limited and need to be dynamically allocated and effectively managed so that the phased array antenna beam agility ability can be given full play to. Meanwhile, radar work modes and work parameters are adjusted in a self-adaptive mode to achieve multiple tasks and multiple functions. The invention provides a phased array radar self-adaptive resource scheduling strategy based on the wave parking rhythm and event driving. The scheduling strategy is combined with work characteristics of the modern radar wave parking rhythm, wave parking serves as a time interval of task scheduling, a computer is scheduled to synchronize radar wave parking, organic combination of search management and tracking management is achieved and can better adapt to work characteristics of a phased array radar, the scheduling success rate and the time utilization rate are high, response to external random events has flexibility, dynamics, quickness and broad-spectrum adaptability, and the method is an optimized scheduling mode.

Description

technical field [0001] The invention belongs to the technical fields of radar and computer, relates to a resource scheduling method of a phased array radar, in particular to an adaptive resource scheduling method of a phased array radar based on wave standing beat and event-driven. Background technique [0002] Phased array radar has limited resources such as time and energy, which need to be dynamically allocated and effectively managed in order to give full play to the beam agility of phased array antennas, adaptively adjust the radar working mode and working parameters, and realize multiple tasks and multiple tasks. function. In the traditional template or adaptive resource scheduling, the radar can only complete specific tasks in a specific time unit, and cannot execute tasks according to the priority in real time, and the time unit is almost fixed, resulting in a lot of waste of time resources. [0003] Looking at the current resource scheduling methods of phased array...
