The Design of Multi-channel Data Recorder Based on Cascade Model Loaded by Missile

In order to improve the sampling precision of data recorders loaded by missile and to meet the the needs of a wide range of parameters sample in the missile launch and flight,this paper proposes a data acquisition method based on the cascade model. The article introduces the cascade model structure in detail, describes the overall structure of the data recorder based on cascade model,and describes the way of sample and storage. Based on this sample mode, the data recorder loaded by missile greatly improved the sampling accuracy. The recorder can sample a wide range of parameters, and can be extended according to need.So this mode is flexible and expand the scope of its use.
