软件时基校准提高时间引信精度

Enhancing Accuracy of ETF by Software Calibrating

在时间引信设计或一般电子引信时间功能及通讯功能设计时,一般会要求一个精密稳定的基准振荡器,目前这样的器件并没有研制成功,而且这样高标准的绝对参数器件成本会极其昂贵。提出将常规的绝对参数设计变为相对参数设计,用软件的方法对目的参数进行补偿式调整,从而在引信振荡源器件规格没有改变的情况下提高了系统精度及通讯速度,系统在软件感应装定电子引信系统中进行了试验,取得了满意的效果。软件感应装定采用软件时基校准方法,保证了时间引信在亚毫秒精度、兆级别以上数传波特率范围的发挥空间。

Usually,an accurate time base oscillator is needed in electronic timing fuze function or communication design,but a device which meets high accuracy,high reliability and high g use has not been developed yet,and such a device must be very expensive.A method was put forward to enhance the accuracy of ET fuze by software calibrating,which uses relative parameter instead of absolute parameter,thus avoid using the devices mentioned above.The test on software induction setting eletronic timing fuze system indicate that the method is valid.
