Description
The 100 mm round resembles a normal 100 mm anti-tank round, and is loaded and fired in the same fashion. The round uses a reduced explosive charge to launch the projectile out of the barrel of the gun at around 400 to 500 m/s. After leaving the barrel of the gun, a small cover falls away from the window on the rear of the missile. The rocket motor ignites 1.5 seconds after firing the missile, and it burns for 6 seconds.
The projectiles use laser guidance. A cone of laser light divided into sectors is projected from the launching tank, each sector having a different frequency or modulation. The missile has a small window in the rear with a sensor to detect the modulation of the light. Using this modulation, the missile steers itself, maintaining its position in the cone. The laser beam-riding guidance system is less spacious than a radio command one, and cheaper and simpler than semi-active laser guidance. The missile is also not prone to radio or optical jamming. On the other hand, a target has to be tracked by laser sight all the time, and the system can not be used on the move.
The missile's flight time to 4,000 meters is approximately 12 seconds. After 26 to 41 seconds the missile self-destructs.

Famous quotes containing the word description:
“The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.”
—Freda Adler (b. 1934)
“Do not require a description of the countries towards which you sail. The description does not describe them to you, and to- morrow you arrive there, and know them by inhabiting them.”
—Ralph Waldo Emerson (1803–1882)
“The great object in life is Sensation—to feel that we exist, even though in pain; it is this “craving void” which drives us to gaming, to battle, to travel, to intemperate but keenly felt pursuits of every description whose principal attraction is the agitation inseparable from their accomplishment.”
—George Gordon Noel Byron (1788–1824)
