Small-caliber Grenade Detonation Time Real-time Set By The Technology Research

In order to realize the trajectory of timing explosive on the small caliber shrapnel at flight ballistic, I develop a technique about shoot real time setter. On the basis of analyzing small caliber shrapnel performance parameters, I test technical parameters and index, define the shrapnel bursting time setter technique and study the key of the three applied techniques on electronic time setter system: digital communication tech, data coding and electromagnetic induction technique.And at same time, I choose the inner pulse coding method on data transmission for the signal of the time setter, use frequency modulation and unrelatable demodulation, and apply error checking to the error control.Meanwhile, I analyze the coupling circuit of the induction setter's system, infer the method for coefficent of the winding's mutual inductance and get the way of the interface to the inductance of electronic time setter system.Finally, I finish transmission test on time setter signal of induction setter system and validate the designed induction setter system's feasibility.
