战术车载通信车内互调干扰

The Study of Intermodulation Interference in the Tactical Vehicle Communication

在战术车载通信车内有多部不同种类的通信设备,当这些设备同时工作时,会产生严重的互调干扰,给战术车载通信设备的正常工作造成了很大的困难,有时候甚至可能导致设备间通信信道完全阻塞,导致整个通信系统陷入瘫痪。首先对互调干扰的产生机理进行了阐述,同时对互调干扰进行了建模和仿真,给出了在战术车载通信车内互调干扰测试的一种方法,最后给出了抑制互调干扰的一些方法。

There are various communication equipments in the tactical vehicle communication, The severe intermodulation interference will be arisen when those equipments parallel, which brings much difficultey to the normal operations of tactical vehicle communication equipments, sometimes even cause the communication channel jamming altogether, and makes the whole communication equipments paralysed. In this paper, the intermodulation interference principle is presented firstly, and meantime, the modeling and simulation are used for the intermodulation interference, and then the general method of intermodulation interference testing is presented. Finally, some interference suppression methods of interrnodulation interference are presented.
