目标轨迹估计装置以及目标轨迹估计方法

目标轨迹估计装置具有:方位信息读入部(41),其读入由接收到来自物体目标(100)的到达电波的多个方位传感器(10)各自得到的表示方位测定值的方位信息、以及表示该方位信息所示的方位测定值中附带的或被一致地设定的方位测定误差的方位测定误差信息;时域分割部(43),其将多个方位传感器(10)各自观测到物体目标(100)的时间按照时间序列顺序分割成多个时域,按照分割成的每个时域分割方位信息读入部(41)读入的方位信息;异常值判定部(44),其按照由时域分割部(43)分割成的每个时域,根据各时域中存在的方位信息所示的方位测定值所示的位置是否集中于一点或者是否集中于由位置和速度构成的状态向量的周边,判定该方位测定值是否表示异常值,将被判定为异常值的方位测定值中附带的方位测定误差,重新设定为降低针对该方位测定值的轨迹估计的可靠度的设定,将被判定为不是异常值的方位测定值中附带的方位测定误差,重新设定为将针对该方位测定值的轨迹估计的可靠度保持原样;测位处理部(45),其按照由时域分割部(43)分割成的每个时域,使用各时域中存在的方位信息所示的方位测定值和该方位测定值中附带的已被重新设定的方位测定误差,估计针对物体目标(100)的各时域中的测位值;以及输出部(46),其输出将由测位处理部(45)估计出的每个时域的测位值按照时间序列连接起来而表示物体目标(100)的轨迹的物体轨迹信息。
