Abstract: The missile-bornedata recorder is a device that can collect and store important dynamic parameters and status information of missile during flight in real time.After recovery, the data recorder can transmit the recorded data to a specific upper computer for analysis and processing.Based on the analysis results, the designer can evaluate the performance of the missile during flight and further modify and improve its functions.With the continuous progress of the level of science and technology, the requirements for missile-borne data recorders are getting higher and higher. Fast processing speed,small structure volume, and large storage capacityare the current development trends of missile-borne data recorders.A hardware, software and structural design for a high-performance missile-borne data recorder is presented.The hardware design of the recorder includes a power board, control boardand communication board, which adopts a modular design and is easy to debug.The software design of the recorder realizes the functions of data collection, encapsulation, storage, and read back, and can automatically overwrite when the storage is full without manual erasure.The structure design of the recorder is mainly aimed at electromagnetic interference factors, and is specially designed to ensure that the volume is as small as possible.In addition, the design and interface of the upper computer are briefly discussed.
