What are laser codes?
A laser designator is a laser light source which is used to designate a target. Laser designators provide targeting for laser-guided bombs, missiles, or precision artillery munitions, such as the Paveway series of bombs, AGM-114 Hellfire, or the M712 Copperhead round, respectively.
What is Podium effect?
When a laser designates a surface that the seeker cannot see, the reflections are blocked (Figure II-6). This situation is called “podium effect.”
What’s the difference between laser and infrared?
Any “light” with wavelengths longer than 700 nm is called infrared and is not normally visible (except sometimes as a dull deep red). In particular, common Optical Wireless laser wavelengths include 780 nm, 810 nm, 850 nm and 980 nm. Optical Wireless systems using LEDs normally operate between 800 nm and 900 nm.
What is the difference between infrared and laser?
Infrared light is radiation in the non-visible spectrum, which extends from 1300 to 1700 nm. Lasers in this range emit radiation in the “eye safe” part of the electromagnetic spectrum, where light is largely absorbed by the cornea and lens, without reaching the retina.
How does a laser designator work on a target?
Laser designator. When a target is marked by a designator, the beam is invisible and does not shine continuously. Instead, a series of coded pulses of laser light are fired. These signals bounce off the target into the sky, where they are detected by the seeker on the laser-guided munition, which steers itself towards the centre…
How does the Northrop Grumman laser designator work?
Northrop Grumman’s LLDR, using an eye-safe laser wavelength, recognizes targets, finds the range to a target, and fixes target locations for laser-guided, GPS-guided, and conventional munitions. This lightweight, interoperable system uniquely provides range finding and targeting information to other digital battlefield systems allowing…
Can a laser be mounted on a ground vehicle?
Cloud cover, rain or smoke can make reliable designation of targets difficult or impossible unless a simulation is accessible through available ground data. Laser designators may be mounted on aircraft, ground vehicles, naval vessels, or handheld.
How does a laser guided munition work?
Instead, a series of coded pulses of laser light are fired. These signals bounce off the target into the sky, where they are detected by the seeker on the laser-guided munition, which steers itself towards the centre of the reflected signal.
