直接频率合成技术在引信时间装定中的应用

小口径速射炮系统 ,通过炮口快速装定 ,达到对目标更高的毁伤概率。该装定系统在弹丸发射时 ,根据弹道参数解算出装定时间信息 ,然后将这一时间信息经编码、调制后向外发送。在弹丸飞离炮口的瞬间 ,将这一时间信息传输该引信 ,实现引信的实时炮口快速装定。该文通过对引信的装定系统进行分析 ,结合直接数字频率合成技术 (DDFS)的特点 ,将DDFS用于引信装定系统中 ,实现对编码信号的FSK调制 ,以满足装定系统数据传输率高、数据传输实时、快速的要求。

Application of Direct Digital Frequency Synthesizer Technique to Fuze Setting System

The small caliber gun system achieves the high destructive possibility on target,by means of the rapid setting fuzes during muzzle exit.The system calculates the setting time message,according to ballistic circumstance parameter,then the sign is sent out after the setting time message has been coded and modulated.The very moment of projectile passing the muzzle,the setting time message is received by fuzes,the setting process of fuzes is finished rapidly.Analysing the fuze setting system,considering the DDFS characteristics,the paper applied DDFS to the fuze setting system to modulate the code signal at the type of FSK and to meet the needs of high data transmitting rate.
