High-Speed Parallel Adaptive Algorithm to Radiation Pattern Array and Its Experimental System

在天线阵发射波束时进行方向图零点控制是现代雷达采用的先进技术之一。讨论了一种期望方向增益最大约束下的唯相位方向图置零算法 ,同时描述了相应的雷达自适应干扰对零阵列处理实验系统。理论分析和实验结果均表明该算法在大多数情况下一般都能有效置零抑制干扰 。

It is one of advanced technologies used in modern radar that control nulls of the beampattern when array antenna radiates beams. This paper describes a phase-only nulling method with the constraints that the pointing direction gain of a linear phased array antenna is maximised, and its corresponding experimental radar adaptive nulling array processing system. Theoretical analysis and experimental results all show that the method has proved useful and practical in most cases.
