Abstract
In order to solve the problem that current launch vehicle noise parameter is short of testing refinement in the ground comprehensive experiment, a low-cost noise simulation system based on the audio card is proposed. On the basis of working principle and performance indicators of the audio card, the feasibility of using audio card to simulate noise environment is analyzed. Using the virtual instrument technology, the hardware structure is designed and software development is completed under LabVIEW platform. The test results show that the signal from the noise simulation system agrees well with the sensor which is sensitive to the noise signal, and the system performance is stable. With the advantages of low cost, strong commonality, and simple operation, the noise simulation system has been successfully applied in noise parameters experiment of launch vehicle telemetry system integrated test.关键词
