【摘要】 分析了扇扫TWS雷达多目标跟踪中的特殊问题,提出了一种扇扫雷达下基于双重扇区划分的航迹预相关方法,该方法可以有效减少点迹航迹关联的判决次数,并通过分析同一目标相邻点迹之间采样间隔的变化规律,提出了目标出现时间的计算方法,进而修正了此种情况下自适应α-β滤波的滤波与外推方程,最后进行了仿真分析。更多还原

【Abstract】 In this paper,the special problems of multi-target tracking in sector scan TWS radar are analyzed,a method of pre-track correlation based on dual sector partition in sector scan radar is proposed,the method can reduce the times of gate correlation greatly.Besides,by analyzing the change regulation of sample interval for the same target,the calculating method for the target appearing time is established,and an adaptiveα-βfiltering and predicting formula for sector scan radar is developed,finally,the simulation is given.更多还原
