Subject field(s)
  • Various Military Titles
  • Weapon Systems
OBS

The Kerrison Predictor was one of the first fully automated anti-aircraft fire-control systems. The Predictor solved the problem by doing all of the calculations mechanically through a complex system of gears. Inputs to its calculations included wind speed, ballistics of the gun and the rounds it fired, angle to the target in azimuth and altitude, and a user-input estimated target speed. Some of these inputs were fed in by dials, which turned gearing inside the Predictor to calculate the range(from the change in angle and estimated speed) and direction of motion.

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.

DEF

A measure of the location accuracy between the object in the image and its geographical co-ordinates in the real world.

CONT

Measurement parameters include point target impulse response measures : range and azimuth impulse response widths(IRW), range and azimuth peak sidelobe ratios(PSLR), integrated sidelobe ratio(ISLR), and absolute location error(ALE), using images of RADARSAT Precision Transponders(RPT).

OBS

DEF

Mesure de la précision de localisation entre l'objet dans l'image et ses coordonnées géographiques dans le monde réel.

CONT

L'erreur de localisation absolue peut être calculée pour un point de l'image en comparant la latitude et la longitude de la position du pic de réponse impulsionnelle du transpondeur avec la position en latitude et en longitude réelle du transpondeur. Les produits standard de RADARSAT générés par le Centre canadien de traitement des données sont traités en utilisant une altitude de zéro mètre (c'est-à-dire au niveau de la mer). De plus, un délai est introduit dans la rétrodiffusion du signal par le RTP. Puisque le radar à synthèse d'ouverture (RSO) est un système utilisant la distance, ce délai d'environ 1,8 microseconde produit un déplacement de la réplique du transpondeur à une distance plus grande (distance mesurée à partir du capteur).

OBS

erreur de localisation absolue; ALE : terme et abréviation uniformisés par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).

Subject field(s)
  • Transport of Goods

DEF

The frequency shift observed at a receiver due to any relative motion between transmitter and receiver.

CONT

The Doppler frequency depends on the component of satellite velocity in the line-of-sight direction to the target. This direction changes with each satellite position along the flight path, so the Doppler frequency varies with azimuth time. For this reason, azimuth frequency is often referred to as Doppler frequency.

A method of winds-aloft observation; that is, the determination of wind speeds and directions in the atmosphere above a station.

Subject field(s)
  • Missiles and Rockets

Researchers employed an innovative guidance strategy to produce new guidance laws that are nonlinear variants of augmented PRONAV.... The new concept led to guidance laws that do not depend on time-to-go, indirectly minimize miss distance, and compensate for both target and missile acceleration. By applying the new guidance strategy to the complete, fully coupled, nonlinear, intercept kinematics, researchers developed two families of guidance laws that account for various levels of cross-channel couplings between the azimuth and elevation guidance channels.
