单脉冲雷达中和、差信号的微波馈线与接收机的连接处是两分系统的边绿地区,常常成为工程研制时不易引起重视的环节。过去不少雷达由于该环节设计不当,造成整机性能恶化。基于这种情况,我们在研制舰载单脉冲雷达时提出了一种半自动波导接口装置。尽管该设想未见到先例,并且加工也有一定难度,但我们大胆地对三根波导馈线同时实现半自动连接作了尝试,在车间工人同志积极配合下,终于设计成功。本文首先描述了该接口的重要性、旧式设计的弊端和新装置的构造,以及新装置如何正确解决了可靠性与可维护性的矛盾,最后给出了整机联试与远洋航行使用中的测试数据。 Monopulse radar and the poor signal of the microwave feeder and the receiver is a two-point system at the edge of the green area, often become engineering development is not easy to pay attention to the link. In the past a lot of radar due to improper design of the link, resulting in deterioration of machine performance. Based on this situation, we proposed a semi-automatic waveguide interface device in the research of shipborne monopulse radar. Although this scenario has not been preceded by any precedent and the processing has been somewhat difficult, we boldly attempted to realize the semi-automatic connection of the three waveguide feeders at the same time. With the active cooperation of the workshop workers, we succeeded in the design. This article first describes the importance of the interface, the disadvantages of the old design and the construction of the new device, and how the new device correctly solves the conflict between the reliability and the maintainability. Finally, Test Data.
