摘　　要：针对导弹弹上空间有限、对载体的重量和功耗有着严格限制等要求,研制了一种具有高可靠性、低功耗、小型化的弹载数据记录仪。本系统主要实现对导弹飞行过程中的场景视频信息进行H.264格式硬件压缩存储以及对飞行姿态等数据进行实时记录并存储至高速大容量SD卡,极大地方便了飞行试验后数据的读出和处理。In view of the limited of the space, the weight of the carrier and the power consumption of the missile, this paper designed a data recorder system with high reliability, low power consumption and small size. The system could receive video data of scene and then realize hardware compressed storage in H. 264 format. At the same time, it can also record the flight status data of the missile in real time and store the data in high-speed and large-capacity SD card, which is easy to read back and process the collected data.
