摘要
针对低频射电阵列海量数据、高带宽、多波束、实时处理的需求,设计了一种基于数字信道化的宽带数字多波束形成技术方案。针对射电天文学信号预处理的需求,该技术同时实现数字波束形成(Digital Beam Forming DBF)和频谱分析的功能,降低了射电阵列信号预处理运算复杂度,同时具有易于硬件实现,实时性高的特点,非常适合低频射电阵列应用。
In this paper,a broadband multi-beam forming technology is designed to cater the requirements of massive data,broadband,multi-beam and real-time processing in low frequency radio array. This technology implements digital beam forming and frequency analysis at the same time in demand for the radio radio astronomy signal preprocessing,not only reduces the radio array signal preprocessing operation complexity,but also simplifies the hardware implementation and improves the realtime ability as well,therefore,it is well suited for radio array application.
