中文摘要:
      相控阵雷达波位编排传统方法难以评价任意波束跃度下的覆盖率、重复率、空域多遍扫描时的累积检测概率、最小扫描时间。为了解决该问题,分析了波束指向、波束跃度、波束宽度和脉冲积累时间的耦合关系,提出了基于点阵图元的波束截面建模方法;建立了求解波位编排最优化问题的两个基本模型,给出了基于遗传算法的最优波位编排仿真流程,在案例中得以验证及应用。结果表明,通过联合运用两个模型,可实现波位编排可视化仿真及指标计算,可获得资源浪费少、累积检测概率高的最优策略。
英文摘要:
      With the traditional method of beam position arrangement for phased array radar, it’s difficult to evaluate Coverage Rate, Repetition Rate, Cumulative Detection Probability of multiple scans and Minimum Scanning Time when beam granularity is arbitrary. In order to solve this problem, this paper analyzed the coupling relationship of beam direction, beam granularity, beam width and dwell time, then proposed a beam section modeling method based on dot-matrix graphic. Thus the two basic models for solving optimization problems of beam position arrangement were built, and the simulation process of optimal beam position arrangement based on genetic algorithm was given, which was validated and applied in specific case later. Through the combination of the two models,the visual simulation and index evaluation of beam position arrangement are realized. Finally, the optimal strategy with less resource waste and high Cumulative Detection Probability is obtained.
