The paper studies a cycle storage system with fixed capacity to monitor fuze battery＇s working voltage and noise,solving the problems of small capacity and low sample frequency.A 4 MB cycle sampling space is designed by adopting the negative delay technology,which implements the function of recording 4 MB data before triggered and then sequentially recording 50 MB data to ensure that the host computer recovers the voltage and noise data correctly and *** pieces of Flash work alternately to avoid the time conflict between commands programming and data *** method can make efficient use of storage space,recording the information before triggered,therefore it ensures the reliability and validity of the measured data.

In order to solve the onboard recorder search problem, a new beacon system based on radio direction finding tech- nique, which indicates the orientation of the recorder, is designed. The system consists of phase-locked loop （PLL）, micro- processor, global position system （GPS） module, power module and so on. The scene simulation verifies the feasibility and reliability of the system. This beacon system can be applied to the recorder search in many fields, and can effectively reduce the search scope and improve work efficiency.
