Aiming at the problems of complex and inefficient missile test methods, and combining with the actual requirements of missile rapid launch, the paper puts forward a new method of missile test. A portable test method based on FPGA is proposed in this paper. This method uses Cyclon IV FPGA chip as the core data processing unit. The core processing unit uses dual-core processor architecture, carries the corresponding communication board, analog and digital card, respectively, completes the corresponding test instruction transmission and data acquisition. The data processing software uses uc/OS II operating system to complete the task scheduling of the whole system. At the same time, portable intelligent data terminal is used to view and analyze test data independently. Experiments show that this method can reduce the volume of testing equipment, reduce the complexity of testing methods and improve the efficiency of testing, so as to achieve rapid launch.
