Abstract: A radar system uses multiple-beam maximum likelihood estimation (MLE) during both search and tracking operations. During search, a four beam sequential beam cluster may be used to search for targets in a region-of-interest. During tracking, a three beam triad may be used to track one or more detected targets. In some embodiments, a beam selector switch may be used to allow two offset receive beams to time share a beamformer output port to generate the four beam sequential cluster.

Abstract translation: 在搜索和跟踪操作期间，雷达系统使用多波束最大似然估计（MLE）。 在搜索期间，可以使用四光束连续光束，聚类来搜索感兴趣区域中的目标。 在跟踪期间，可以使用三光束三元组来跟踪一个或多个检测到的目标。 在一些实施例中，波束选择器开关可以用于允许两个偏移接收波束来共享波束形成器输出端口以生成四个波束顺序簇。
