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.
Claims24
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.
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.
An apparatus for presenting measurement data of a launched projectile, 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 receiving means being adapted to correlate the indicated position to a corresponding position in the target area,
- a radar for receiving radiation transmitted by or reflected by the projectile while it is in flight,
- a computer for determining, from the received radiation, measurement data of the projectile in a coordinate system of the radar, and for 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
- a display for presenting the transferred measurement data to a user.
An apparatus for determining a distance between a predetermined direction of a launched projectile and a landing point of the projectile, 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 receiving means being adapted to correlate the indicated position to a corresponding position in the target area,
- a Radar for receiving radiation transmitted by or reflected by the projectile while it is in flight, and
- a computer for
- determining, from the received radiation, measurement data of the projectile in a coordinate system of the radar,
- determining, from a launch position of the projectile and the corresponding position, the predetermined direction, and
- determining the distance between the predetermined direction of the launched projectile and the landing point of the projectile.
