多功能可扩展DBF方法研究

Research on a multi-function scalable DBF method

介绍一种多功能可级联数字波束形成系统的设计方法。从原理上阐述了DBF过程的分解方法,并在此基础上设计可级联可扩展DBF系统,重点描述标准DBF模块设计方法、DBF合成工作原理和级联设计方法,并介绍了子阵化DBF设计。通过对级联DBF过程的时间分析,明确该方法具有很高的系统时效性,具备较好的工程实现性,为相控阵雷达系统设计提供了一种高效的多功能DBF实现方法。

A multi-function cascadable DBF system is designed. Based on the decomposition method of the DBF process described in principle, the cascadable and scalable DBF system is designed with emphasis on the working principle of the DBF synthesis, and the design of the standard DBF module and the cascade. The sub-array DBF is also designed. With the analysis of the time of the cascaded DBF process, providing an it is verified that the method features high timeliness and good engineering realization, efficient multi-function DBF method for the phased array radar system.
