机载雷达内外总线接口小型化设计

Miniaturization Design of Airborne Radar Internal and External Bus Interface

机载火控雷达存在多种复杂的内外接口关系。通常 ,在雷达的信息控制处理中心———信号 /数据处理机中针对不同的接口类型 ,设计相应的接口模块 ,模块数量较多。为了提高雷达的处理能力 ,除了直接设计处理能力更强的信号 /数据处理模块之外 ,压缩各种接口模块的数量也是行之有效的手段之一。文中分析了雷达各种内外接口关系的现状 ,介绍了三合一多功能接口模块的设计思路及实现方法 ,对于设计体积更小、功能更强的机载多功能火控雷达具有重要的现实意义。

There are many complicated interfaces in airborne fire control radar and between Radar and Avionics. Generally, according to different interface type, different interface modules in the digital signal processor and data processor are designed, and there are a large number of modules. In order to improve processing ability of radar, it is one of effective methods to compress the number of interface modules, besides improving the performance of the digital signal processor and data processor. The paper analyzes a number of internal or external interfaces of radar, and introduces a design method and describes a three-in-one multifunctional interface module. It is of important significance for designing smaller and stronger multifunction airborne fire control radar.
