摘要
相控阵雷达与常规机械扫描雷达相比,其对空中目标的探测更加灵活、快速,能够在微秒量级形成定位的雷达波束,先进事件调度方式是发挥这一优势的关键所在。对于固定调度间隔和优先级调度算法,级别较高的事件抢占位置后不再调整,对于冲突的同等级别或级别低的事件进行时间窗内调整。其优点就是运算简单,无需反复调整,同时也产生较多破碎的时间片段,对于平均时间偏移率也无法实现优化调整,浪费雷达有限的资源。本文将弹簧振子模型引入到雷达事件调度算法中,利用弹簧双向调整原理,在最小能量的约束下,实现对雷达申请事件有反馈地自适应调度。结合对弹簧振子固有参数的设计可以在计算量与评价指标之间进行取舍,增加了算法可设计的空间。
Comparing with conventional mechanical scanning radar, phased array radar can detect air targets more flexibly and quickly, steered radar beams can be formed in microsecond ; key factor to take advantages of this prop- erty is by applying advanced event scheduling algorithm. For fixed schedule interval and priority scheduling algo- rithms, after high priority events occupy their positions, adjustment will be not conducted; only conflicted events with the same priority or lower priority will be adjusted computation is simple and doesn＇t need to do adjustment and optimization adjustment of mean time offset rate is un in repe able time window. Adv atedly; while many to achieve, therefo antages of this algorithm time fragments will be generated re limited radar resource is was- ted. By introducing spring vibrator model into radar event scheduling algorithm, and by using dual - directional ad- justment principle of spring, under minimum energy constrain, radar application events can be scheduled with feed- back adaptively. Through designing spring vibrator inherent parameters to achieve tradeoff between computation load and assessment index, more designable space can be provided for the algorithm.
