摘　　要：瞄准现代化信息战争中有源电子干扰超宽带、大功率、多目标作战能力需求,将超宽带光储频技术与有源相控阵相技术相结合,构建并设计了一套基于光储频的超宽带相控阵干扰系统。基于光延时网络结合波分复用技术实现超宽带光储频,并通过实时时间延时技术实现超宽带有源相控阵发射多波束合成。系统具有大有效辐射功率发射、同时多波束发射以及超宽带瞬时干扰特性,有效解决了传统数字储频、非功率合成体制有源电子干扰系统有效辐射功率小、多波束能力不足、干扰带宽受限等问题。Aiming at the need of active electronic inference system with ultra-wideband,high-power and multiple target in the modern informational warfare.An ultra-wideband phased array electronic inference system applying the technology of the Fiber-Optical RFM(Radio Frequency Memory)and the active phased array is designed and constructed.In this system,the Fiber-Optical RFM is realized based on optical delay network combined with wavelength division multiplexing(WDM),and multi-beam forming of ultra-wideband active phased array transmission is realized using true time delay(TTD).The system has the characteristics including high effective radiated power,transmission with parallel multi-beam and ultra-wideband instantaneous inference.Compared to the traditional active electronic inference system using of the digital radio frequency memory and without power synthesis,the new system effectively solves the problems that capability of parallel multi-beam is insufficient,effective radiated power is lower,and inference bandwidth is limited.
