The invention belongs to the field of radar system resource management, in particular to a beam dwell scheduling method for a cooperative distributed system. The present invention comprehensively considers the influence of the priority of the task working mode and the deadline on the priority of the task, uses the HPEDF method to calculate the comprehensive priority, and establishes a beam according to the characteristics of multi-station cooperative implementation of radar task scheduling in the collaborative distributed system The resident scheduling optimization model is solved by a heuristic method based on time pointer analysis, and a beam resident scheduling method for cooperative distributed systems is formed. The invention solves the beam dwell scheduling problem of the cooperative distributed system in which the sub-radars can work independently and cooperatively when needed.
Description
A beam dwell scheduling method for cooperative distributed systems technical field The invention belongs to the field of radar system resource management, and particularly relates to the implementation of multi-station cooperative self-adaptation in a distributed system Method for beam dwell scheduling. Background technique The air defense guidance radar with single-station radar as the core is affected by stealth targets, anti-radiation missiles, low-altitude targets, etc. Threats, it is difficult to deal with the complex battlefield environment, and is encountering the bottleneck of development. Distributed system consisting of multiple single-station radars The system can take advantage of the diversity of spatial distribution, thereby improving the anti-strike capability of the combat system. Hence, the concept of distributed systems Get constant research. The distributed system is to adapt to multiple radars with different systems, different frequency bands, ...
