摘要 对几种主要的角分辨率准则进行了综述及对比研究。首先分析了单目标的半功率点宽度(3dB波束宽度),讨论了不同窗函数加权及波束扫描对波束宽度的影响,并比较了不同谱估计方法分辨率的定量公式。更一般地,对于双目标情形,分析了双目标谱均值与双目标中点谱值比较、目标测角均方差、目标分辨概率三种不同分辨率准则的应用范围及影响因素,推导了基于中值比较法的最小方差信号无畸变响应波束形成器(MVDR)角分辨率理论公式,计算机仿真实验证实了上述结果,并提出相应修正。 The paper overviews and compares the main angular resolution criteria.Angular resolution for single source scenario is usually denoted by half-power bandwidth,namely 3dB beamwidth in spatial domain.Beam scanning and window function's weightings have different influences on the 3dB beamwidth.The results of 3dB beamwidth for several spectral estimators are included.Furthermore,several angular resolution criteria for two sources are introduced.The above analyses are verified by computer simulation results.
