机载多功能射频系统是21世纪防空电子对抗的新威胁

New Threat in the 21st Century: Airborne Multifunctional Radiofrequency System

美国空军第四代战斗机F 2 2上的低可探测性 (LO)多功能射频系统 (MFRFS)AN/APG 77,以及将要为联合攻击战斗机 (JSF)设计研制的机载多功能射频系统 (MFRFS) ,主要特征是使用了先进的有源电扫阵 (AESA)天线。通过对AESA的共享 ,F 2 2的MFRFS能同时执行雷达、电子战和通信功能 ,其超视距目标探测、识别与拦截能力 ,丰富多彩的电子对抗招式 ,以及飞机具有的低可探测性能 ,使之成为 2 1世纪夺取空中优势的重要武器系统 ,必将给未来防空电子对抗构成严峻的挑战。

The low observability (LO) multifunctional radiofrequency system (MFRFS), AN/APG 77 on F 22, and another MFRFS being developed for joint strike fighter (JSF), which makes a feature of using an advanced active electronic scanning array (AESA), can perform radar, EW and communication functions nearly simultaneously by sharing the AESA. Over the horizon detection, identification and acquisition function, and various ECM sleight of hand the MFRFS is possessed of, and F 22′s stealth, all of these should make it an important air dominance weapon system in the 21st century, and it should give a serious challenge to future air defense ECM surely.
