摘要
波束域积累检测应用于相控阵雷达一直是雷达专家的关注重点,该技术的应用可平滑雷达系统空域覆盖曲线,优化相控阵雷达时间能量编排,相应地可降低雷达系统规模及成本。介绍了波束域积累检测基本原理、性能评估准则及计算机仿真方法。在设定的仿真约束条件下,通过计算机仿真分析了波束域积累检测所带来的性能得益以及波束交叠电平、检测概率、虚警概率、波束宽度等影响波束域积累检测性能的各个因素,在此基础上提出了工程实施方面的建议。
Accumulative detection in beam domain used for phased array radar has attracted researchers＇ attention for many years. This technique can smooth the space covering curve of radar system, optimize the time-energy arrangement of phased array radar, and reduce the complexity of radar system. In this paper, the basics of the accumulative detection method in beam domain, the performance evaluation criteria and the computer based simulation method are introduced. In computer simulation, for the given constraints, we analyze the performance benefits from the accumulative detection in beam domain and introduces the various factors that affect the performance of accumulative detection in beam domain, such as beam-intersect level, detection probability, false alarm probability, beam width, and so on. Based on these works, some suggestions on implementation are made.
