摘要
多DSP构成的机载雷达数字信号处理分系统在宽温条件下进行开关测试,具有测试时间长、开关次数多、现场噪音大的特点,需要进行远程自动控制。基于标准工控继电器输出模块和ATX电源,设计了自动开关测试平台以及主控机和数字信号处理分系统的测试控制软件。该测试平台组成简单、可靠,长时间连续试验时可无人值守,满足了机载雷达数字信号处理分系统开关测试的实际需要。
The muhi-DSP-based airborne radar digital signal processing sub-system is switching-tested under a wide range of temperature with the characteristics of long test duration, thousands of switching operations and noisy workaround, so the remote automatic control is needed. Based on the standard relay output module and ATX power supply, the auto-switching test platform and the testing control software of host controller and digital signal processing sub-system are designed. The system offers simple composition, reliable and continuous unmanned operation in the whole testing process. It meets the demand for an practical airborne radar signal processing system.
