First Claim
Patent Images
1. A method of presenting measurement data of a launched projectile, the method comprising:
- providing an image representing a target area,receiving an indication of a position in the image, the indicated position corresponding to a corresponding position in the target area,receiving, using a radar, radiation transmitted by or reflected by the projectile while it is in flight anddetermining, from the received radiation, measurement data of the projectile in a coordinate system of the radar,transferring the measurement data from the coordinate system of the radar into a coordinate system with origin at a launch position of the projectile and with a horizontal reference line going through the corresponding position in the target area, and presenting the transferred measurement data to a user.

Abstract
In a method of determining a deviation of a path of a projectile from a predetermined path, the method uses an image of a target area in which the desired path or direction is pointed out. Subsequently, the real direction or real path is determined and the deviation is determined.

1. A method of presenting measurement data of a launched projectile, the method comprising:
-
providing an image representing a target area, receiving an indication of a position in the image, the indicated position corresponding to a corresponding position in the target area, receiving, using a radar, radiation transmitted by or reflected by the projectile while it is in flight and determining, from the received radiation, measurement data of the projectile in a coordinate system of the radar, transferring the measurement data from the coordinate system of the radar into a coordinate system with origin at a launch position of the projectile and with a horizontal reference line going through the corresponding position in the target area, and presenting the transferred measurement data to a user. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A method of determining a distance between a predetermined direction of a launched projectile and a landing point of the projectile, the method comprising:
-
providing an image representing a target area, receiving an indication of a position in the image, the indicated position corresponding to a position in the target area, receiving, using a radar, radiation transmitted by or reflected by the projectile while it is in flight, determining, from the received radiation, a landing point of the projectile, determining, from a launch position of the projectile and the corresponding position, the predetermined direction, and determining the distance between the landing point of the projectile and the predetermined direction. - View Dependent Claims (9, 10, 11, 12)
