Method and an apparatus for determining a deviation between an actual direction of a launched projectile and a predetermined direction
First Claim
1. A method of determining a deviation between an actual direction of a launched projectile and a predetermined direction, the method comprising:
- providing, using a camera fixed to a radar, 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;
determining, using the radar, the actual direction of the projectile;
determining a launch position of the projectile;
determining, from the launch position and the corresponding position, the predetermined direction; and
determining the deviation between the actual direction of the projectile and the predetermined direction,wherein the receiving step comprises rotating the camera and radar to have the position in the target area presented at a center or with a predetermined offset from the center in the image.

Abstract
A method and apparatus for determining a deviation between an actual direction of a launched projectile and a predetermined direction includes providing, using a camera fixed to a radar, 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, determining, using a radar, the actual direction of the projectile, determining a launch position of the projectile, determining, from the launch position and the corresponding position, the predetermined direction and determining the deviation between the actual direction of the projectile and the predetermined direction. The indicating step include rotating the camera and radar to have the position in the target area presented at a center or with a predetermined offset form the center in the image.

6. An apparatus for determining a deviation between an actual direction of a launched projectile and a predetermined direction, the apparatus comprising:
-
a camera for providing an image representing a target area; an input member for receiving an indication of a position in the image, the input member being adapted to correlate the indicated position to a corresponding position in the target area; a radar for determining the actual direction of the projectile; means for determining a launch position of the projectile; a first computer for determining, from the launch position and the corresponding position, the predetermined direction; and a second computer for determining the deviation between the actual direction of the projectile and the predetermined direction, wherein the input member is configured to receive an input and subsequently determine the position as a position at a center or with a predetermined offset from the center in the image. - View Dependent Claims (7, 8, 9, 10)
