Abstract:
The small-caliber gun system achieves the high dest ruct ive possibility on target , by means of the rapid sett ing fuzes during muzzle exit . The system calculates the set ting t ime message, according to ballistic circumstance parameter, then the sign is sent out after the sett ing time message has been coded and modulated. T he very moment of pro jectile passing the muzzle, the set ting t ime message is received by fuzes, the sett ing process of fuzes is f inished rapidly. Analysing the fuze set ting system, considering the DDFS characterist ics, the paper applied DDFS to the fuze set ting system to modulate the code signal at the type of FSK and to meet the needs of high data transmitt ing rate.
