摘　　要：软件无线电通信架构源自美军联合战术无线电系统,在军用、民用领域得到广泛应用;MHAL是SCA关键技术之一,用于实现软件与硬件的解耦;为测试验证软无硬件平台的SCA标准符合性,文章依据MHAL应用程序接口标准提出测试方法;标准主要包括GPP、DSP、FPGA的MHAL接口和RFchain消息等几个部分的内容,规定了其接口函数、消息格式和消息命令等;针对MHAL接口,通过设计测试用例调用API接口函数进行MHAL消息传输,检查消息传输正确性,完成软件接口测试;针对RFchain命令,通过MHAL消息发送控制命令,利用标准仪器测量信道输出响应、射频参数,验证硬件平台接口符合性和性能指标;最后搭建测试系统,对多家单位研制的软无装备进行测试,结果表明测试方法合理可行,能适应不同架构的软无被测设备,有效验证硬件平台MHAL接口符合性。Software communication architecture(SCA) is derived from the project of US Joint Tactical Radio Systems and widely used in military and commercial fields. Hardware abstraction layer MHAL is one of the key technologies of SCA, the decoupling of software and hardware isrealized. In order to test the conformity for SCA Standards in the no hardware and software platform, according to the standard, the test method is proposed. The standard mainly include GPP API, DSP API, FPGA API and RFChain information. The standard specifies interface functions, message formats and commands. FMHAL interface test is designed to call API interface functions by test cases, and MHAL message transmission and check is conducted, the siftware API test is completed. For the RFChain command test, the control command is sent through MHAL message, and the channel output response and RF parameters are measured by standard instruments to verify the compliance and performance index of the hardware platform interface. Finally, the test system is built to test the SDR platforms developed by different manufacturers. The results show that the test method is reasonable and feasible, which can adapt to the SDR equipment with different architectures, and the MHAL interface compliance of hardware platform is effectively verified.
