基于软件无线电的电台综合测试系统研究

随着信息化的建设,电台已广泛应用于军事和民用领域。目前电台多波段、多制式并存,不同波段、不同制式的电台测试方法不尽相同,对电台的测试造成问题。对某一波段、某一制式电台的测试,需要选用不同性能、不同功能的测试仪器组成测试系统,如音频信号发生器、音频信号分析仪、射频信号发生器、射频信号分析仪、频谱分析仪、跳频信号发生器等。这种测试系统存在仪表种类多、体积大、成本高、效率低、操作复杂等问题。本文研究基于软件无线电的电台综合测试系统,可在一个通用硬件平台下调用不同的程序,实现多体制调制解调、跳频信号发生、射频分析、频谱分析、调制域分析、音频发生、音频分析、误码测试等多种功能,能解决多波段、多制式电台的测试问题。通过软件升级,也能适应未来电台测试需要。

Radio integrated test system based on software radio research

The radio has been widely used in military and civilian fields with the construction of information technology.At present,The multi-band multi-standard radioes coexist,It caused by different test methods。Test of a band and standard radio need to use different properties and different functions of the test apparatus composed of a test system,Such as audio signal generator,audio signal analyzer,RF signal generator,the RFsignal analyzer,spectrum analyzer,frequency hopping signal generator.The test system instrument types,large volume,high cost,low efficiency and complicated to operate and other issues.In this paper,Radio integrated test system based on software radio can achieve multi-system modulation and demodulation,frequency hopping signal,RF analysis,spectrum analysis,modulation domain analysis,audio occur,audio analysis,bit error testing by calling different programs in a common hardware platform.It can solve the problem of multi-band multi-standard radio test.Through a software upgrade,it can also adapt to the future radio test.
