This video allows for anyone within the field of regard to be tracked-both live and retroactively, for forensic analysis.
2.
The main features that distinguish these devices are : field of regard and field of view, spatial resolution, screen geometry, light transfer mechanism, refresh rate and ergonomics.
3.
The active electronically scanned radar is mounted on a rotating mechanical gimbal with a 360 degree field of regard, although the antenna itself has a 110 degree field of view.
4.
At the very front is the JHMCS ( Joint Helmet-Mounted Cueing System ), this missile is capable of locking on to a target that is in its field of regard said to be up to 90 degrees off boresight.
5.
ARGUS is a form of wide-area persistent surveillance system that allows for one camera to provide such detailed video that users can collect " pattern-of-life " data and track individual people inside the footage anywhere within the field of regard.
6.
Automatic object-tracking software called Persistics from the Lawrence Livermore labs allows users to auto-track every moving object within the field of regard ( 36 sq miles ) and generate geolocation chronographs of each individual vehicle and pedestrian's movements, making them searchable via geolocation query.
7.
Due to laser safety considerations, the gimbal may not shine on anything on the ISS . To avoid this, the gimbal is designed with mechanical stops and electromechanical limit switches so that its field of regard ( the area where it can point ) is limited to 36?wide in elevation and 106?in azimuth, where the azimuthal axis is generally in the direction of motion of the ISS . Because of the gimbal field of regard geometry, the flight system can only perform downlinks when the ISS is north of the ground station.
