摘　　要：射频数字化可以去除接收机和发射机中模拟变频部分电路，简化射频前端设计。这将给电子对抗系统结构带来巨大的变化，并由此可能引发一场技术变革。文章提出一种新型射频数字化的架构，对其关键技术、性能特点进行了研究。在L波段进行了技术验证，测试表明射频数字化具有优异的技术性能，具有广阔的应用前景。RF（ Radio Frequency） digitization can remove some circuit of the analog tuner, by that the radio front of the system can be simplified. This can induce the great change, even the technique reform of the electronic counter system. A new RF digitization architecture is pro- posed in this paper, the key techniques, performances and specialties are also introduced. The test is performed at L band, the results indicate that RF digitization has excellent performance, and also prefigure this technique can be widely used in the future.
