摘要
针对脉冲激光引信应用于中小口径常规弹药过程,由于体积严格受限而造成引信内部电磁干扰严重的问题,结合发射、接收模块工作原理,说明在其内部采取电磁干扰抑制措施的必要性。通过分析发射、接收模块电磁干扰产生机理,提出采用双重屏蔽方法抑制辐射干扰,采用线性阻抗稳定网络、缓冲网络和共差模合成扼流圈结合的多重滤波技术抑制传导干扰。对各措施作用效果进行仿真与实验,结果表明:厚度为1.55 mm钢材料对辐射干扰具有良好屏蔽效果;接收模块输出干扰信号峰峰值减小至70 mV,约为原干扰信号的1/40。这些方法大幅度降低了脉冲激光引信内部的电磁干扰,且工作稳定可靠。
Abstract
For the serious electromagnetic interference(EMI) problem in fuze arisen from volume constraints in the application of pulsed laser fuze to medium/small caliber conventional ammunition, the paper analyzes the necessity of adopting anti-interference measures internally with the principle of transmitter and receiver modules. Dual shielding which inhibits radiated interference(RI) and multi-filtering technique composed of linear impedance stabilization circuit, buffer network, CM-DM integrated choke, which inhibits conducted interference are proposed by analyzing EMI mechanism of transmitter module and receiver module. Simulations show that steel shield with the thickness of 1.55×10-3 m has good shielding effect on RI. Experiments prove that the peak value of receiver module interference signal reduces to 70 mV, which is only a fortieth of original noise. These strategies which greatly reduce internal EMI of pulsed laser fuze are feasible and effective.
