And to obtain such target,the acquisition and storage systemthat could record data parameters during the flight test procedureshould be mounted on theseaircraftsand weapon systems.On the basis of theory research for data acquisition and storage system and design principles for engineering system, and for technical specifications of a certain kind of flight measurement system, this thesis is intended for a data acquisition and storage system based on STM32, which uses SamsungK9F1G08U0C NAND Flash asthe medium for storage, USB interface to realize the communication between the hardware and PC. It achieves the acquisition and storage for 16 channel analogy signals, 4 channel RS422 digital signalsand 1 TTL signal. And it also plishes the data-reading,unpacked analysis and graphical display after the flight test. This thesis first analyzes the overall designschemeof the data acquisition and storage system,
