| 摘要: |
| 在脉冲压缩系统中，雷达探测的距离分辨率与系统的相位特性紧密相关。因此，作为其核心器件，T/R组件的相位特性是其非常重要的一个指标参数。从T/R组件相位特性的原理出发，从4个方面分别对T/R组件相位特性进行了分析，并相应地提出了优化T/R相位特性的方法。以X波段T/R组件为设计实例，对所提出的优化方法进行设计验证。优化前后的测试数据显示，文中所提优化方法切实有效，可以在一定程度上改善T/R组件的相位特性，为T/R组件相位特性的优化设计提供了很好的方法和依据。 |

| Abstract: |
| In pulse compression radar system, the detection range is closely related to the phase characteristics of the system. As a core component, the phase characteristic of T/R module is an important indicator. In this article, the reasons of T/R module phase nonlinearity are represented by analyzing the distortion mechanism and four methods are proposed to promote the phase linearity. In the end, an X-band T/R module was designed and manufactured to verify the validity of the methods. The test results indicate that the phase distortion of T/R module is improved by using the proposed methods, which provides good methods and basis for the phase characteristics optimization of T/R modules. |
