| 摘 要： | 传统干涉仪测向采用模拟鉴相器,鉴相误差较大,即使数字鉴相器也不具备同时多信号分辨能力.本文提出了一种基于数字信道化接收机的全数字化鉴相器进行测向的方法.经理论分析和仿真实验,该方法测向精度有很大提高,且可以实现同时多信号的分辨.

| Abstract: | Analog phase discriminator used in traditional interferometer has great phase error;even digital phase discriminator is not capable of simultaneous multi-signal discrimination.A direction of arrival(DOA) estimation method by using of an all-digital phase discriminator based on digital channelized receiver is proposed.Theoretical analysis and simulation show that this method features high direction-finding accuracy and good simultaneous multi-signal discrimination capability. |
