Abstract: An automated method for cueing a high resolution video camera to a mobile object involves first detecting the presence of an object by a wide-area surveillance asset such as a radar and using the radar's positional information to cue the video camera iteratively, while updating the positional information each time. Then, a video analytics algorithm detects the object and generates more accurate positional and rate information on the object, which is then used to cue the video camera into a higher resolution setting for classifying/identifying the object. Once the object is identified, the positional and rate information is updated and the updated information is used to further cue the video camera into a higher resolution setting for recording a video clip of the moving object while the video camera is dynamically steered.

Abstract: A method for determining, in three dimensions, the location of a moving ground object observed in a region by a video camera. A terrain map supplies altitude for the latitude and longitude of each terrain point. The terrain information is combined with camera location, field of view, and orientation to produce a computed terrain map relative to the camera. A video analytics step processes the video and locates moving target(s) in two Cartesian coordinates. The coordinates are processed with the camera information to produce target location in terms of azimuth and elevation angle. The computed map information is combined with the angular target location to produce latitude, longitude, and altitude of the target. The target location information is used for further investigation or to attack the target. Also, a method for determining the third dimension of a 2-D radar track to cue a camera or fuse with camera data.

Abstract: According to an embodiment of the disclosure, a computer implemented method of configuring a land-based radar system for scanning a scan region is disclosed. The method comprises dividing the scan region into a grid of blocks and obtaining a terrain elevation data for the scan region. For an elevation angle for the radar system, determining those blocks in the grid that are visible to the radar system and those blocks that are not visible to the radar based on the terrain elevation data. Then, step of determining the visible blocks is repeated for all elevation angles in a predefined set of elevation angles for the radar system. Next, an optimal scan elevation angle for the radar system is determined as the scan elevation angle which resulted in the maximum number of visible blocks in the scan region and the radar system is set to the optimal scan elevation angle.
