摘要: 综合考虑影响威胁度的5个参数,给出辐射源威胁度评估准则与方法。将辐射源威胁度参数融入被动雷达任务优先级的设计中,提出一种综合优先级算法(HTHPEDF),根据辐射源威胁度动态地调整任务优先级。运用该综合优先级算法实现任务自适应调度,设计调度收益与调度代价的评价函数。通过仿真验证了算法的有效性,该算法以较低的调度代价获得较高的调度收益,可有效提升任务综合调度能力。

Abstract: Considering comprehensively the five parameters affecting threat degree, the criteria and methods for assessing the threat degree of radiation source are given. A comprehensive priority algorithm (highest threat,highest priority and earliest deadline first, HTHPEDF) is proposed in the design of the task priority of the passive radar with the radiation source threat parameters which can be dynamically adjusted according to the degree of the threat of radiator. On this basis, the task adaptive scheduling implementation, the performance evaluation and the scheduling cost function are designed. The simulation results show that the algorithm obtains higher task scheduling performance with lower cost and has certain advantages for enhancing task scheduling ability.

Key words: passive radar, the degree of the threat, task priority, scheduling efficiency, scheduling cost, adaptive scheduling
