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。
Small-caliber rapid-fire gun system, rapid assembly through the muzzle, to achieve a higher probability of damage to the target. When the projectile is launched, the loading system calculates the loading time information according to the ballistic parameters, and then encodes the time information and sends it out after modulation. When the projectile flew away from the muzzle, the time information was transmitted to realize the real-time muzzle mounting of the fuze. In this paper, by analyzing the loading system of fuze and combining with the characteristics of direct digital frequency synthesis (DDFS), DDFS is used in fuze loading system to realize the FSK modulation of the encoded signal to meet the data transfer rate High, real-time, fast data transfer requirements.
