一种基于多门限的周视激光引信抗干扰方法研究

摘要

A novel anti-interference method for panoramic laser fuze based on multithreshold is pro -posed in this paper .The characteristics of target echo waves and the interferences are studied by theoretic analysis , software simulation and experiments .Based on this , an anti-interference algorithm , which can ad-just the circumstance of clouds and mist , is designed .The simulating and experimental results show that , with the assurance of target acquisition capability , the anti-interference ability of the laser fuze is tremen-dously improved by the multi-threshold technique , and the fuze has certain target acquisition ability under the circumstances of interference .%提出了一种基于多门限的周视激光引信抗干扰方法，通过理论分析、软件仿真和试验确定了云雾干扰和目标的回波特性，据此设计了一种能够应对云雾环境的抗干扰算法。软件仿真和云雾试验表明，多门限抗干扰技术在保证了对目标探测能力的前提下，显著提高了激光引信的抗云雾干扰能力，在干扰环境下，引信具有一定的目标识别能力。
