  • Patent number: 11243306
    Abstract: In a method for estimating a position of a missile, an incident angle of a signal of a radar irradiated to the moving missile is calculated. The incident angle is defined by an angle between a measurement vector indicating a direction from the radar toward the missile and a movement vector indicating a moving direction of the missile. A distance compensation value from a point on a surface of the missile to an origin point of the missile is calculated based on the calculated incident angle. A distance from the radar to the origin point of the missile is calculated based on the calculated distance compensation value and a distance from the radar to the point on the surface of the missile. A position of the missile is estimated based on a position of the radar and the calculated distance from the radar to the origin point of the missile.
