Parameter measurement of concrete structure's dynamic response is of special importance in the experimental studies of the projectile's penetration against concrete targets. Various kinds of structure response methods are analyzed in this paper, methods of measuring the dynamic parameters of concrete structure and the burying methods of sensors are also presented here. Huge memory data sampling device is used to record the real time dynamic parameters of the concrete structure response. The sampled data are processed and analyzed accordingly. The results show that the measuring method is right, the data got are real, reliable and it is of preference value.
