BTTW-DratsaB Posted March 28, 2009 Posted March 28, 2009 Could be to do with this? Missile Protection System for Vehicles During the past few years terrorist threats have increased dramatically and tremendous efforts have been made to counter these threats. Sniper, small arms and Rocket Propelled Grenade (RPG) attacks have emerged as tactics of choice for guerrilla and terrorist groups engaging U.S., allied, and United Nations forces in Iraq and Afghanistan. Small arms and low cost RPGs are a continuing threat to US personnel and aviation assets and both must be detectable by a common sensor. During the mid-1990’s Trex Enterprises, Corporation, San Diego, CA, employees, developed a projectile tracking system capable of detecting and tracking missiles, including missiles from small arms fire such as bullets and RPG's. Projectiles of interest are typically traveling at a substantial fraction of the speed of sound or even faster than the speed of sound, and therefore become hot due to aerodynamic heating. A telescope focuses infrared light from a relatively large field of view on to an infrared focal plane array. In a projectile detection mode, the system searches for the infrared signature of the fast moving projectile. The telescope's field of view is steered in the azimuth by a step and stare mirror which is driven by an azimuth drive motor mounted on a frame. When a projectile is detected the system switches to a tracking mode and the mirror is steered by the azimuth drive motor and a pivot motor to track the projectile. A short pulse high repetition rate laser in a laser radar system provides a pulsed laser beam which is optically co-aligned with the telescope axis. Mirror angular position information, laser radar pulse travel time and the missile spot position on the detector array are used by a computer to calculate bullet trajectory information and to determine the source or origin of the projectile using known ballistic trajectory methods. Although only a small portion of the total trajectory may be captured, the very accurate position information permits extrapolation to determine the launch point of the projectile. Trex Enterprises has released information on a projectile tracking system for acquiring and precisely tracking a projectile in flight in order to reveal the source from which the projectile was fired. The source is revealed by the back projection of a 3-dimensional track file. In preferred embodiments the system is installed on a vehicle, such as an un-manned blimp or other aircraft, road vehicle or ship, for locating and destroying small arms fire directed at the vehicle. A kill system may also be included on the vehicle to destroy the source of the projectile.http://www.defense-house.com/tvanews-2007jan01.htm Specs: GA-Z87X-UD3H, i7-4770k, 16GB, RTX2060, SB AE-5, 750watt Corsair PSU, X52, Track IR4, Win10x64.

CE_Mikemonster Posted April 25, 2009 Posted April 25, 2009 In actual fact that is why it was so successful against the T-55s and T-60s during the Angolan Civil war because the t's couldn't see over the thick african bushveld while the Olifant could which resulted in a better sighting of the target and thus a better kill rate, in fact off hand I dont know of any olifants lost to enemy tanks. Good info there, it would never have occured to me that having a high profile can actually be an advantage in some environments. Too many cowboys. Not enough indians. GO APE SH*T
RedTiger Posted April 25, 2009 Posted April 25, 2009 Good info there, it would never have occured to me that having a high profile can actually be an advantage in some environments. Think about it this way too; the lower the profile, the less gun depression possible. Less gun depression means that its harder to get in a hull-down position.

BTTW-DratsaB Posted November 5, 2009 Posted November 5, 2009 I would love to see these ^ videos translated. They all look really interesting and would make a nice change from the usual USA/EU/IDF etc vehicle/weapon systems we always see in documentaries in the West. Anyone know if it's been done?

zakobi Posted November 5, 2009 Posted November 5, 2009 Cool australian M1A1 camo (Baracudda) http://www.benandcamera.com/portfolio-photography/military-vehicle-camouflage/ That must keep it warm enough at the winter :music_whistling:
Vekkinho Posted November 5, 2009 Posted November 5, 2009 ^^^^^ Yeah, it might freeze in Australia... [sIGPIC][/sIGPIC]
zakobi Posted November 5, 2009 Posted November 5, 2009 IMO a great made movie: ps. not all danes are shit talkers like ElvenDane and latinindenmark. pps. it's me who is greatgoofy, if you wonder by some comments...
