摘要由于受常规弹药空间和系统功耗的限制,激光近炸引信应用于常规弹药过程中,无法布置多个激光器和多个激光接收器,同时,系统结构要求尽量简单,故传统的光束布局方式无法直接应用。现设计出一种新型的单光束大视场脉冲旋转周向扫描方案。结合磁电检检测模块,加工制作了初始原理样机,从而可有效减小常规弹药引信空间占用率和系统功耗。针对电机电磁干扰影响因素,采用多种方法屏蔽电磁信号对回波信号的干扰,进行了抗电磁干扰实验,结果表明这些方案能够有效屏蔽电机的电磁干扰。61140

Title Fuze Azimuth Detection Technology Using Motor Rotation And Anti-jamming Method
Abstract
Due to the power consumption of conventional ammunition space and system constraints,Laser proximity fuze used in the process of conventional ammunition,it can not arrange a plurality of lasers and a plurality of laser receivers,meanwhile, the system requires a structure as simple as possible,therefore, the traditional layout of the beam can not be used directly.Now we have designed a new type of single-beam large field pulse rotates the circumferential scanning program.Combined magnetic inspection detection module, I manufacture an initial prototype, which can effectively reduce the footprint of conventional ammunition fuzes rate and system power consumption.For motor electromagnetic interference factors, people using a variety of methods to shield the electromagnetic signals of the echo signal interference, the paper carried out anti-electromagnetic interference experiment results show that these programs can effectively shield the motor electromagnetic interference.

1.1 课题研究的背景
现代战争,从某种意义上说是武器的较量,武器的先进性在战争中具有十分关键的作用。近炸引信出现以来就备受关注,近炸引信可以使用于各种各样的弹药中,发挥出非接触发作用功能。从理论研究到装备部队中最早实现的是雷达引信,由于战场复杂的电磁环境和雷达工作的波段宽,使雷达引信可靠性不能满足现在的作战需要,急于寻找一种新的探测方式。
