HIT PROBABILITY [11 records]

Record 1 2021-08-31

English

Subject field(s)
  • Weapon Systems
  • Energy (Physics)
CONT

To penetrate a target, KE projectiles rely on velocity and not an explosive charge.... Historical research indicates that KE projectiles are responsible for forty percent of tanks knocked out in battle. Because KE projectiles are normally fired at very high velocity, they have a very flat trajectory(flight path), a decreased time of flight, and increased hit probability. The effectiveness of KE projectiles decreases at longer ranges, since the projectiles slow down during long flights.

OBS

kinetic energy projectile; KE proj: designations officially approved by the Department of National Defence and the Canadian Forces.

Record 2 2011-11-25

English

Subject field(s)
  • Small Arms
  • Target Acquisition
CONT

While the SFCS has a number of features and capabilities designed to vastly improve target identification and hand-off among a number of operators, its core is a muzzle velocity sensor. The system sits on the Picatinny rail of any weapon and draws on a number of acoustic sensors to characterize how the weapon is performing between the time the primer of a round is struck and the bullet leaves the barrel.... Meteorological and other sensor inputs are fed into a ballistics computation that then gives a range azimuth correction to the operator. It helps the operator correct his aim point so that his probability of hit for second, third and fourth rounds is that much more accurate.

Record 4 2008-02-22

English

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
  • Search and Rescue (Paramilitary)
CONT

Final search [of avalanche victims.] You are now within 4 meters and getting closer. ... Many experienced practitioners agree that at this stage the job of your [avalanche] transceiver is largely done. Within the 2 m range the probe may be the most efficient tool to pinpoint the victim. ... Be systematic. ... Once you have a probe strike leave the probe in and begin digging - hard and efficiently. Additional probing may be valuable to determine where the head is and the orientation of the person.

CONT

Probability of Finding [an Avalanche] Victim. A probe contact is usually recognized by a soft, spongy feeling. The theoretical probability of contacting a buried person is about 70% for coarse probing on the first pass; with fine probing, the probability is close to 100%. In practice, the probability of finding a victim is lower. For example, probes can often deflected in the snow, altering the effectiveness of the search grid. In addition, probers sometimes fail to notice when the probe has hit a body.

CONT

Les techniques de sondage. Il s'agit de secours organisés [de victime d'avalanche]. Le sondage d'une zone est réparti en unités de 15 sondeurs au maximum. Chacune comprend en plus un chef de vague (aux ordres du chef d'opération) et 1 ou 2 pelleteurs munis chacun d'une sonde de rechange. En cas de «touche». Lorsqu'un sondeur sent une résistance, le chef de vague (en principe plus expérimenté) vient vérifier. La sonde est laissée en place. Un pelleteur donne une sonde de remplacement et la vague continue son travail jusqu'au dégagement de toutes les victimes. Les pelleteurs dégagent la neige en commençant en aval à une distance à peu près égale à la profondeur de la «touche».
