下一代支援干扰吊舱发展综述

Summary of the Development of the Next-Generation Electronic Attack Jamming Pod

为了应对高度竞争威胁环境,各国启动了下一代干扰吊舱的研制计划,美国海军为提升EA-18G的作战能力积极推动的NGJ项目是下一代干扰吊舱的典型代表。美军下一代干扰吊舱采用涵道式冲压空气涡轮发电技术,在不占用阵列天线安装空间的前提下实现了大功率自发电;采用基于氮化镓T/R组件构建宽带多功能有源相控阵阵列,大幅提升了干扰输出功率;采用数字化开放式架构支持能力快速升级迭代和功能的高度集成。在战术上,下一代干扰吊舱将重点提升对雷达的远距离副瓣干扰能力、定向多目标干扰能力,并实现雷抗、通抗等功能的综合化。

To deal with the highly competitive environment, the U.S Navy is developing next generation jammer(NGJ). The NGJ system is powered by the airstream flowing through a submerged turbine connected to a generator. The primary recipient of this prime power is a wideband, polarization diverse, Active Electronically Scanned Array(AESA) with Transmit/Receive(T/R) modules that contains efficient Gallium Nitride(GaN) amplifiers. Also featured is an all-digital, scalable, reprogrammable Software Defined Receiver/Exciter Unit that provides the technique generation. The capability of NGJ is proposed to be jamming radar through side-lobe, jamming multi-target with narrow beams and multi-functional.
