预警机在未来战场上所面对目标的 RCS 越来越小，为了获得足够的作用距离，需要增加雷达的功率口径积，在载机功率资源一定的情况下，增大天线口径是最有效的方法。然而机载预警雷达天线口径受雷达罩外形尺寸及飞机总体气动构型等因素的限制，因此需要合理选择预警机总体气动构型并对雷达罩气动外形进行优化；通过合理的结构总体布局设计，有效利用雷达罩的气动外形，保证天线口径的最大化，文中就雷达罩气动外形选择以及雷达结构总体设计的相关问题进行探讨，可为预警机雷达结构总体设计提供参考。

The RCS of target faced by the early warning aircraft is getting smaller and smaller.It is re-quired to augment the power-aperture product for gaining the adequate detection range.It is the most effica-cious way to enlarge the antenna aperture when the power provided by the aircraft is limited.However,the antenna aperture of AEW radar is limited by the outline of the radome as well as the overall aerodynamic con-figuration of the aircraft.On the one hand,it is demanded to choose the overall aerodynamic configuration of the aircraft reasonably and to optimize the outline of the radome and make an effective use.On the other hand,it is demanded to design the overall layout of the equipment of antenna system precisely,so as to ensure the antenna aperture indexes.The related issues about the aerodynamic shape choice of radome and the overall structral design of AEW radar are discussed.
