Aiming at the special environment for cluster munitions dispersion, a storage telemetry system for transmitting and collecting parameters in dispersion was designed. To avoid the heavy work of device handling and data acquisition and increase the safety factor of the experiment, the overall design of the system was given, the structure and the theory of the system were discussed, the multi-scale testing and multi-store model were realized. The experimental results show that the system is good at data storage and wireless transmission with low error rate, meeting the test standards.
