Unlike radar ( except Doppler radar ), Noctovision is incapable of determining the distance to the scanned subject.

Unlike weather radar, which relies on the aircraft's own equipment, the satellite service can give a pilot information about weather anywhere in USA and Canada.

Unlike the radar unit, which must send the pulse out and then receive its reflection, the target's receiver does not need the reflection and thus the signal drops off only as the square of distance.

Unlike the radar, which knows which direction it is sending its signal, the receiver simply gets a pulse of energy and has to interpret it.

Unlike the Mercury, it used ejection seats, in-flight radar and an artificial horizon — devices similar to those used in the aviation industry.

Unlike other reported types of UFOs, black triangle UFOs have been reported to be visible to radar, as was the case with the famous Belgian UFO wave.

Unlike lower radio signal frequencies, light does not bend around the curve of the earth or reflect off the ionosphere like C-band search radar signals, and so LIDAR is useful only in line of sight applications like higher frequency radar systems.

Unlike the majority of the DEW Line radar sites which were abandoned or automated, this site which changed in 1989, known as CAM-MAIN, remains a manned operation, with about 18 people, as part of the North Warning System.

Unlike radar which frequencies and use are controlled by the FCC lidar is not.

* Unlike an active radar homing missile, the missile does not alert the target to the fact that it is homing in on it by illuminating it with radio waves.

* Unlike semi-active radar homing missiles, the electronics needed to calculate and follow an interception path do not need to be built into each missile, reducing their complexity, weight and cost.

* Unlike radio command guided missiles, because the missile's radar receiver is much closer to the target than the ground station, more accurate tracking information can be generated for the system's computer.

Unlike the ZSU the M163 has no search radar, and has limited engagement capability against aircraft at night.

Unlike Mike Harris's provincial government, Cousens was a supporter of photo radar to discourage speeding in the Greater Toronto Area.

Unlike primary radar systems that measure only the range and bearing of targets by detecting reflected radio signals, SSR relies on targets equipped with a radar transponder, that replies to each interrogation signal by transmitting a response containing encoded data.

Unlike previous detectors, using heavy water would make the detector sensitive to two reactions, one sensitive to all neutrino flavours, which would allow a detector to measure neutrino oscillations directly.

Unlike beta decay, the observation of neutral current interactions that involve particles other than neutrinos, requires huge investments in particle accelerators and detectors, such as are available in only a few high-energy physics laboratories in the world ( and then only after 1983 ).

Unlike the simple counting board used in elementary schools, very efficient suanpan techniques have been developed to do multiplication, division, addition, subtraction, square root and cube root operations at high speed.

Unlike that, the speed of light is constant and only its direction changes.

Unlike modern systems, which can be applied to widely different databases and needs, the vast majority of older systems were tightly linked to the custom databases in order to gain speed at the expense of flexibility.

Unlike common serial ASCII terminals, the 3270 minimizes the number of I / O interrupts required by transferring large blocks of data known as data streams, and uses a high speed proprietary communications interface, using coaxial cable.

Unlike other throwing events, javelin allows the competitor to build speed over a considerable distance.

Unlike the physics of rigid bodies where the equations of motion describe the physical location of the rigid body, fluid dynamics describes the flow as a velocity field, i. e. a solution associates each point in space with a vector that represents the speed and direction of the flow at that point.

Unlike other printer types, pen plotter speed is measured by pen speed and acceleration rate, instead of by page printing speed.

Unlike show hunter classes, which reward calmness and style, jumper classes require boldness, scope, power, accuracy, and control ; speed also is a factor, especially in jump-off courses and speed classes ( when time counts even in the first round ).

Unlike the 8600's " four computers in one box " solution to the speed problem, the STAR was a new design using a unit that we know today as the vector processor.

Unlike most of the navigable waterways in the Norfolk Broads, Breydon Water is not subject to a speed limit.

Unlike modern engines they have no radio, no cutting equipment, only a single ladder, and were relatively slow with a maximum speed of around, a comfortable cruising speed of, no power steering, and sensitive on corners.

Unlike Levkov's design, however, these boats generally lacked a lift engine, using power and short wings to create lift at speed.

) Unlike Doom and Quake, Descent does not use BSP trees for visibility culling ( to speed up rendering ), instead taking advantage of the game's use of collections of cubes to form rooms and tunnels.

Unlike many bars, a speed dating event will, by necessity, be quiet enough for people to talk comfortably.

Unlike in burlesque, the performer in the modern Americanized form of stripping minimizes the interaction of customer and dancer, reducing the importance of tease in the performance in favor of speed to undress.

Unlike a wound-rotor motor, the rotor circuit is inaccessible and it is not feasible to introduce extra resistance for starting or speed control.

Unlike in California, however, riders do not return to ground level in their boat ; instead, they exit the boat immediately after the Jack Sparrow in the treasure room scene, then take a speed ramp up to the ground floor gift shop.

Unlike construction cranes where the work speed was determined by the relatively slow progress of the masons, harbor cranes usually featured double treadwheels to speed up loading.

Unlike the clippers, steamers offered a consistent speed and the ability to keep to a schedule.

Unlike the F-111, its variable-sweep wings were programmed automatically by speed and could be swept under G loading.

Unlike the other two lakes, the Millington Stage drained over the trap rock crest of Long Hill.

Unlike trap and skeet, which are games of repeatable target presentations, sporting clays simulates the unpredictability of live-quarry shooting, offering a great variety of trajectories, angles, speeds, elevations, distances, and target sizes.

Unlike a sting operation that targets a known or suspected criminal, a honey trap establishes a general lure to attract unknown criminals.

Unlike the earlier novel's warnings about Faustian overreaching, this novel's devastating apocalypse strongly suggests that medicine had become too timid and ultimately too late.

Unlike its successors, the EBS and EAS, CONELRAD was never intended to be used for severe weather warnings or local civil emergencies.

Unlike traditional round gauges, many levels of warnings and alarms can be set.
