射频隐身是未来先进战机隐身要求的重要方面，研究机载电子设备、尤其天线系统的射频隐身技术是现实的和迫切的；特殊设计的相控阵系统能够同时担负雷达、电子战和高速数据链等各种战术任务，是未来先进战机不可或缺的重要电子装备。文中从相控阵天线系统的辐射特性与LPI、散射特性与LO和战术任务规划等方面论述了实现多功能相控阵系统射频隐身的技术方向，理清研究的先后层次，指出未来研究的发展方向。

It is practical and necessary for the RF stealth of the airborne electric equipments, especially for that of the antenna systems. It is the important area in the stealth of the advanced fighter. The special designed phased array can perform several tactical missions simultaneously, such as the radar, the electronic warfare, the high speed data-link and so on. It will be the most important airborne electric equipment in future. This paper presents the development trends of the RF stealth of multifunctional phased arrays in the relationship between the radiation characteristic and LPI, that between the scattering characteristic and LO and the tactical mission planning in order to make the sequence clarity and look for the key subjects to be enforced.
