基于声地震动加权融合的弹丸落点定位算法

摘要

针对弹丸落点被动声定位方法中，受环境条件影响大、非爆炸性弹丸探测性能差的缺陷，提出基于声-地震动加权融合的弹丸落点定位算法。该算法仍以相关算法为基础，通过测向交叉定位实现落点定位，引入地震动信号，并将地震动、声两种定位方式的定位结果进行动态加权融合。双五元十字面阵为阵列模型的模拟实验表明：传感器阵列有效探测到两种目标信号，地震动方式能够实现目标源定位，且和声定位结果加权融合后稳定性得到提高。%Aiming at the weakness of poor ability on detecting unexploded bomb of passive acoustic location, and it was liable to be influenced by environmental condition,a weighed locating method of bomb point based on fusion of acoustic and seismic signal was put forward.On the basis of correlation algorithm,the landing point was located by DOA location,and the weight fusion of earthquake and sound signal was carried out.Double-five-element-square-array was taken as the basic structure of sensor array,and simulated experiment was con-ducted to ensure the feasibility and efficiency.The signal analyzed and locating result proved that target signal of two ways was detected by sensor array,and the seismic locating method is effective on point locating,of which the stability was improved by weigh fusion with acoustic locating method.
