摘要
灵敏度是电台的重要指标,随着通信技术的发展,采用跳频和扩频技术的抗干扰电台越来越多地应用到现代超短波通信系统中。由于跳频图案和扩频编码对于用户是不可知的,那么抗干扰电台灵敏度的检测难以实施。本文通过设计通信控制器,运用同型号电台相互通信的方法,并采用内嵌式计算机系统完成调制音频数据产生、信噪比和误码率分析、收发状态转换等功能,来实施音频灵敏度和数据灵敏度的检测。实际检测结果证明,这种方法能够实现未知跳频图案和扩频码情况下电台灵敏度的自动检测,提高了抗干扰电台检测水平。
Sensitivity is an important capability. With the deplovement of communication technique, the frequency--hopping and the spread spectrum technology more and more apply in the modern ultra--short wave communication system. Because the frequency--hopping design and the spread spectrum code are the core technologies, and the factory is impossible to provide to the user, it is difficult to implement sensitivity testing. This article design a communication controller and uses the same model radios communicating to avoid the frequency--hopping design and spread spectrum code question in the test procedure, simultaneously uses embedded computer system to complete radio- frequency signal program control attenuation, the spectral analysis, modulation singal data creating, signal--to--noise ratio and error rate analysis, receiving and dispatching state transition and so on. Pratice satessiates that the test system can realize expands hopping radio rs automatic detection in the unknown frequency-hopping design and spread spectrum code situation with a high intelligence level.
