一种基于有源开关的阵列天线带内模式项RCS减缩方法
|
Abstract:
针对干扰天线分时工作的特点，结合雷达散射截面的模式项理论，研究通过对比馈电网络调控模式项的几种方式，采用有源开关对馈电网络进行控制，实现隐身与干扰双模式分时工作；同时优化开关数量，有效减缩带内模式项RCS，保持了天线较高的辐射效率。
In view of the time-sharing operation characteristic of the jammer antenna and grounded in the mode-item theory of radar cross section (RCS), this paper compares several approaches for controlling the mode items via the feed network. An active switch is employed to govern the feed network, thereby enabling time-sharing operation between the stealth mode and the jamming mode. Furthermore, by optimizing the number of switches, the in-band mode-item RCS is effectively reduced, while a high radiation efficiency of the antenna is preserved.
