【摘要】：針對特殊的水下目標(biāo)跟蹤環(huán)境(強雜波干擾),提出一種高效的目標(biāo)軌跡終結(jié)方法:基于量測位置分布統(tǒng)計的軌跡終結(jié)方法.目標(biāo)消失前后,目標(biāo)軌跡的一些關(guān)鍵信息統(tǒng)計特征發(fā)生顯著變化,如量測位置分布.基于此原理,依據(jù)量測位置分布的變化情況能有效區(qū)分虛假軌跡與真實目標(biāo)軌跡,進而確定目標(biāo)是否消失.基于量測位置分布統(tǒng)計的軌跡終結(jié)方法適用于高密度雜波環(huán)境.仿真與分析表明此軌跡終結(jié)方法提高了虛假軌跡的刪除概率,減小了目標(biāo)軌跡的誤刪除概率,因而增強了水下目標(biāo)跟蹤性能.
[Abstract]:For the special underwater target tracking environment (strong clutter interference), an efficient target trajectory termination method is proposed, which is based on the statistics of measured position distribution. Before and after the target vanishes, the statistical characteristics of some key information of the target trajectory change significantly, such as the distribution of the measured position. Based on this principle, the false trajectory can be effectively distinguished from the real target track according to the change of the measured position distribution, and then the target can be determined whether the target disappears or not. The trajectory termination method based on the statistics of measured position distribution is suitable for high density clutter environment. Simulation and analysis show that this trajectory termination method improves the probability of false trajectory deletion and reduces the probability of false deletion of target trajectory, thus enhancing the performance of underwater target tracking.
