Systems and methods for coordinating radar data and image data to track a flight of a projectile
First Claim
1. A system for coordinating radar data and image data to track a flight of a projectile, comprising:
- a radar;
an imager providing a plurality of images of an area into which a projectile is to be launched; and
a controller receiving the images and an identification of a target within a first one of the images, the controller identifying a target line connecting the target and a launch position of the projectile, the controller also receiving data from the radar relative to at least a portion of a trajectory of the projectile, the controller generating image based trajectory data by correlating the radar data and a second one of the images, the controller altering the second image to include the image based trajectory data within the second image and the target line within the second image,wherein the controller is configured to position the target line in the second image based on an orientation and position of a radar coordinate system and an imager coordinate system.

Abstract
A system for coordinating radar data and image data to track a flight of a projectile includes a radar, an imager, and a controller. The imager provides an image of an area into which a projectile is to be launched. The controller receives the image and an identification of a target within the image and identifies a target line connecting the target and a launch position of the projectile. The controller also receives data from the radar relative to at least a portion of a trajectory of the projectile, generates image based trajectory data by correlating the radar data and the image, and alters the image to include the image based trajectory data within the image and the target line within the image.

14. A method for coordinating radar data and image data to track a flight of a projectile, comprising the steps of:
-
receiving by a controller a plurality of images and an identification of a target within a first one of the images as well as radar data relating to at least a portion of a trajectory of a projectile traveling through a field of view represented by the first image; identifying by the controller a target line connecting the target and a launch position of the projectile; generating by the controller image based trajectory data by correlating the radar data and the images; altering a second one of the images to include the image based trajectory data and the target line within the second image; and manipulating, by the controller, the second image to position the target line in the altered second image based on an orientation and position of a radar coordinate system and an imager coordinate system. - View Dependent Claims (15, 16, 17, 18, 21)

19. A method for coordinating radar data and image data to track a flight of a projectile, comprising the steps of:
-
receiving by a controller an image and an identification of a target within the image as well as radar data relating to at least a portion of a trajectory of a projectile traveling through a field of view represented by the image; identifying by the controller a target line connecting the target and a launch position of the projectile; generating by the controller image based trajectory data by correlating the radar data and the image; and altering the image to include the image based trajectory data and the target line within the image, wherein the controller identifies a radar coordinate system corresponding to the data received from the radar and an image coordinate system corresponding to the image and correlates the data from the radar with the image by coordinate translating the data from the radar to the image coordinate system through a three dimensional translation and rotation. - View Dependent Claims (22)
