摘　　要：为了提高通信的保密和抗干扰性,跳频和扩频技术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是核心技术,厂方不可能提供给用户,跳扩频电台许多重要指标的检测难以实施。采用同型号电台对通的方法,有效避开电台测试过程中的跳频图案和扩频编码问题,同时采用变频的方法解决电台之间的同频干扰,并采用内嵌式计算机系统来完成射频信号的程控衰减和频谱分析、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,通过测试算法的优化设计,开展电台收发状态下所有重要指标的检测。实际检测结果证明,采用对通和变频方法能够实现在未知跳频图案和扩频码情况下跳扩频电台指标的自动检测,提高了跳扩频电台检测水平。In order to enhance communication the security and the anti-jamming, 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 many important of DS-FH radio target examinations. This article uses the same model radios communicating to avoid the frequency-hopping design and spread spectrum code question in the test procedure, simultaneously uses the frequency mixing to solut frequency disturbance between radios, through test algorithm optimization design and 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 satessiats that the test system can realize expands hopping radio＇s automatic detection in the unknown frequency-hopping design and spread spectrum code situation with a high intelligence level.
