| 摘 要： | Ku频段信号测向时通常使用比幅测向法,认定测向范围内接收到的信号幅度值最大的方向为信号来波方向,但该方法测向精度较低。针对比幅测向法的不足,提出了一种比幅测向法与相关干涉仪测向法相结合的测向模型,利用比幅测向法来解模糊,而相关干涉仪测向法用来保证较高的测向精度。详细阐述了新方法的实现步骤,介绍了测向天线阵列的设计。试验结果表明,该方法测向精度高,处理速度快,适于硬件实现。

| Abstract: | The direction finding of Ku band signals usually uses amplitude comparison method, regarding the direction of the maximal amplitude as the direction of arrival, but the precision of this method is low. To overcome the shortcoming of the amplitude comparison method, a new DF method is proposed combining amplitude comparison method and correlation interferometer, using amplitude comparison method to solve ambiguity and using correlation interferometer to guarantee high DF precision. The paper describes the new DF method in detail and introduces the design of the antenna array. Experiment results prove that the new method has the characteristics such as high DF precision and fast speed and fits hardware realization. |
