  3. Laser designator - Wikipedia

    en.wikipedia.org/wiki/Laser_designator

    A laser designator is a laser light source which is used to designate a target. Laser designators provide targeting for laser-guided bombs, missiles, or precision artillery munitions, such as the Paveway series of bombs, AGM-114 Hellfire, or the M712 Copperhead round, respectively. When a target is marked by a designator, the beam is invisible ...

    An algorithm compares speckle patterns captured by a rolling shutter and a global shutter. It uses the differences between the patterns to calculate the vibrations and recreate the audio.

  6. Look-down/shoot-down - Wikipedia

    en.wikipedia.org/wiki/Look-down/shoot-down

    Look-down/shoot-down radars have been enhanced with electronic programs that process the radar image and search for moving objects, which are detected by looking for Doppler shifts in the radar return. See moving target indication. The radar removes all stationary objects (e.g. the ground and buildings) from the display and shows only moving ...

    An ARRL Numbered Radiogram is a brevity code used in composing ARRL Radiograms during times of radio congestion. The code is used to transmit standard messages, sometimes with customized text, very quickly by experienced ARRL National Traffic System (NTS) message traffic handlers. In use, ARRL Numbered Radiograms are messages encoded as one or ...

    en.wikipedia.org/wiki/Kurzsignale

    The Kurzsignale code was intended to shorten transmission time to below the time required to get a directional fix. It was not primarily intended to hide signal contents; protection was intended to be achieved by encoding with the Enigma machine. A copy of the Kurzsignale code book was captured from German submarine U-110 on 9 May 1941.
