A tracking algorithm for multiple-maneuvering targets based on joint probabilistic data association（JPDA）is proposed to improve the accuracy for tracking algorithm of traditional multiple maneuvering targets.The interconnection probability of the two targets is calculated,the weighted value is processed and the target tracks are obtained.The simulation results show that JPDA algorithm achieves higher tracking accuracy and provides a basis for more targets tracking.
针对传统铅酸蓄电池SOC(state of charge)预测方法在线测量精度不高的问题,提出基于电化学反应原理的预测方法。该方法首先对电池进行放电,利用放电电流、电压和硫酸浓度的关系得到电池的硫酸浓度,再根据硫酸浓度与电解液密度的关系得到电解液密度,最后利用电解液密度与SOC的对应的关系得到电池的SOC。研究结果表明,该方法具有操作方便,实时监测准确度高的优点。
Simulation has become an important method for missile flight research to reduce cost and improve accuracy. This paper concerns missile flight trajectory and attitude calculation. As a result, mechanical analysis and modeling are done, the characteristics of missile flight decoding algorithm and attitude parameters are analyzed, the missile trajectory is dynamically simulated in a vertical plane and the missile attitude is real-time displayed. The description of missile flight process in a labo- ratory has provided a basis for actual missile flight.
