降低阵列天线RCS研究进展综述

Research Progress on Reducing RCS of Array Antennas

阵列天线系统作为平台通信系统的一部分,在其工作时,自身的散射特性会影响整体通信平台的隐身性能,所以降低阵列天线的RCS显得尤为重要。本文首先概述了降低阵列天线RCS的原理,然后根据相关原理将目前降低阵列天线RCS的技术分为四类。从每一类RCS技术的适用性出发,对应整理了相关阵列天线降低RCS的方法。对比并总结这几种方法的优劣性,最后从实用的角度出发讨论面向未来的可应用的降低阵列天线RCS的技术。

The array antenna system serves as a platform communication system.When it works,its own scattering characteristics will affect the stealth performance of the overall communication platform,so it is particularly important to reduce the RCS of the array antenna.This paper first outlines the principle of reducing the RCS of array antennas,and then divides the current technology of reducing RCS of array antennas into four categories according to the relevant principles.Starting from the applicability of each type of RCS technology,the methods for reducing RCS with related array antennas are sorted out.The advantages and disadvantages of the several types of methods are compared and summarized,and finally the technology for reducing the RCS of array antennas that can be applied in the future is discussed from a practical point of view.
