| 摘要: |
| 非协同目标连续波雷达无法用一付天线实现同时收，发。发射天线与接收天线之间的空间隔离度往往不能满足要求，需要采用馈通过消技术。本文对这种馈通过消技术做了初步探讨，推导出环路的传递函数，分析了环路的稳定问题，提出了设计中一些需要考虑的问题。 |

| Discussion on Feed--Through Cancellation Loop |

| () |
| Abstract: |
| Non-cooperative target CW radar can not transmit and receive signals simultane-ously using an antenna. The space isolation between transmission and receiving antenna usually isnot satisfied, and therefore feed--through cancellation techncque must be used. This paper willdiscuss this feed--through cancellation technique. Transfer function of the loop is given and sta-bility of the loop is analysed in the paper. Some problems which must consider in design are pro-posed. |
