Aiming at the special environment for cluster warhead ejection and scattering process, a storage telemetry system was designed to transmit and collected the parameters in the ejection and scattering process. The designed system could avoid the heavy work of devices handling and data acquisition and increase the safety factor of the experiment. The overall design of the system was given in this paper, the structure and the theory of the system was discussed, realizing the multi scale testing, multi store model. Experimental results showed that the system was very good at completing the data storage and wireless transmission functions with low error rate, and was compliance with test standards.
