弹头目标高精度微动特征提取实验研究

Experimental study on high-precision micro-motion signature extraction of warhead target

弹道目标实际作战场景回波数据获取困难,对弹头目标微动特性的研究多停留在理论层面,且多基于理想散射点回波模型.为此,依据宽/窄带交替的弹头目标高精度微动特征提取原理,构建了弹头目标微动效应微波暗室模拟平台,用以产生逼近真实条件下的弹头目标回波数据;设计了光滑弹头模型和粘贴锡箔纸团弹头模型两种实验场景,对实验数据进行了分析.实验结果验证了弹头目标中存在的微动成分情况以及相关微动特征提取算法的有效性,为相关算法投入工程应用奠定了基础.

It is difficult to obtain the echo data of ballistic target in actual combat scenarios,but the research on the micro-motion characteristics of warhead target mostly stays at the theoretical level,and is mostly based on the echo model of ideal scattering point.To this end,a microwave anechoic chamber simulation platform for war-head target micro-motion effect is constructed to generate echo data of warhead target approximating real condi-tions.Two model experiment scenarios are designed:smooth bullet and pasted tinfoil ball bullet,with the experi-mental data analyzed.The experimental results verify the presence of micro-motion components in the warhead targets and the effectiveness of the relevant micro-motion signature extraction algorithm,laying a foundation for the application of the relevant algorithm in engineering.
