摘要
针对目前缺少激光引信抗烟幕干扰等效动态交会试验场景构建方法,且未考虑不同浓度区间对引信响应特性的影响等问题,提出基于浓度分层的烟幕等效试验场景构建方法,结合烟幕干扰仿真模型及等效场景设计,设计并形成典型遭遇条件、不同浓度状态的烟幕区域,模拟引信接近及穿过烟幕干扰场景,基于引信在不同浓度分层、有无等效目标条件下的动态交会回波,复现引信在真实烟幕干扰环境下的响应特性,通过仿真和理论模型相结合的手段,支撑烟幕粒子及流动参数的适配性选择,具备实验室条件下引信抗烟幕干扰性能验证能力,满足激光引信抗烟幕遮蔽干扰指标及边界条件验证等需求.
Abstract
Aimming at the current lack of laser fuze anti-interference dynamic verification test method,and the influence of different concentration intervals on the response characteristics of the fuze is not considered,a meth-od of constructing smoke screen equivalent test scenes based on concentration stratification was proposed,com-bined with smoke screen interference simulation model and equivalent scene design,based on the dynamic cross-echo of the fuze in different concentration stratification and with or without equivalent target,the response char-acteristics of the fuze in the real smoke interference environment were reproduced,Through the combination of simulation and theoretical model,the adaptive selection of smoke screen particles and flow parameters were sup-ported,the fuze had the ability to verify the anti-smoke interference performance under laboratory conditions,which met the requirements of the laser fuze's anti-smoke screen interference index and boundary condition veri-fication.
