<p><P>PROBLEM TO BE SOLVED: To provide a radar system capable of precisely calculating the position of a target, while inhibiting degradation of the responsiveness. <P>SOLUTION: The target position correction part 24 calculates a point on the segment, connecting the measurement relative position POt and the estimated relative position Pft as the relative position Pt for this time, when the estimated relative position Pft is estimated for this time by the target position estimation part 23, if the POt in the figure is calculated as the measurement relative position for this time by the radar positioning part 10. Here, the target position correction part 24 calculates the position of relative position Pt so that the smaller the distance Q to the measurement relative position POt is, the smaller the number of tracking times R will be, and the larger the mean valueϕup to this time of the absolute value of the difference of the directional angle dθbetween the directional angle of the measurement relative position POt and the directional angle of estimation relative position Pft, the nearer it will be to the measurement relative position POt. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
