应用于引信遥控装定的火控信息交联装置

自差式多普勒无线电引信发射和接收装置是引信遥控装定的重要内容.在装置中引入单片机和FPGA技术,能快速、准确的装定已经出炮口300 ms以上的密集弹药,选择工作方式,可供选择的工作方式有近炸、碰炸、遥控炸、定时(距)炸.引信具备近目标发射电磁波功能,能有效抗有源干扰、海杂波干扰和信道干扰.FPGA的高度集成特性减小了编码和解码、调制与解调电路的体积,减小了引信工作电路.

A Fire Control Information Transfer Device Used for Fuze Remote Setting

The autodyne Doppler radio fuze transmitter-receiver is a important device of fuze remote control setting.The advanced techniques of FPGA and SCM are introduced into this device,which would quickly and precisely set hundreds of fired ammunitions over 300m distant from muzzle,make choice of operating mode,including close blast,contact blast,remore control blast,timing blast etc.This make the fuze radiate electromagnetic wave only when it is very colse to target so as to protect the fuze against the active jamming,sea clutter interference and channel jamming.The high-integration density of FPGA chip can reduce the size of coding,decoding,modulation and demodulation circuits,as well as operating circuit of fuze.
