基于支持向量机与DS证据理论的复合触发技术

Compound Trigger Technology Based on Support Vector Machine and DS Evidence Theory

针对CCD立靶采用单一外触发方式可能造成的漏测、虚警、存储与处理冗余数据量过大而影响到系统工作效率及可靠性等问题,提出采用支持向量机(SVM)与DS证据理论信息融合的方法,将被测试武器的枪炮口火焰、弹丸激波、天幕靶信号等信息进行预处理,生成目标的初速度、着靶速度、存速率等弹道信息对目标进行状态估计,而后进行加权融合,最终实现复合触发。仿真与实验结果表明,该触发方式在保证系统可靠性的同时降低了虚警率和数据存储与处理量。

In view of CCD vertical target using external trigger mode may cause the leakage test,false alarm,storage and processing a mass of redundant data,affect the efficiency and reliability of system,the support vector machine(SVM)with the DS evidence theory of information fusion method is proposed,the weapons gun fire,projectile shock wave,and sky target signal are pretreated,and then,the targets initial velocity,the target velocity,the storage rate and other ballistic information are estimated,and then the weighted fusion is carried out to realize the compound trigger. Simulation and experimental results indicate that this method reduces the false alarm rate and data storage and processing capacity while ensuring the reliability of the system.
