“Lasers and high-power microwave devices long have been eyed as competing directed-energy attack options. However, researchers are now combining the two to produce smaller, cheaper, more powerful, nonkinetic weapons,” according to Aviation Week.
“An advanced concept, pioneered by BAE Systems’ researchers, uses light to multiply the speed and power at which HPM [high-power microwave] pulses… Researchers predict leaps of 10–100 times in power output within two years,” making it possible to generate the 100-gigawatt pulse needed “to disable a cruise missile at a useful range.”
The development of HPM weapons has been hobbled for the last 30 years by seemingly intractable cost, size, beam-control and power-generation requirements. Tests of modified air-launched cruise missiles carrying devices to produce explosively generated spikes of energy were considered big disappointments in the early 1990s because of an inability to direct pulses and predict effects. New active electronically scanned array (AESA) radars can jam emitters or possibly cause damage to electronic components with focused beams. But power levels and ranges are limited by aperture size.
BAE Systems’ photonically driven technology could open the way to much smaller and more powerful electronic jammers, nonkinetic beam weapons for cruise and anti-ship missile defenses, and stealth-detecting sensors.
“You could put a [sensor] system on a fighter-size aircraft that could generate enough power, with a 1-ft. resolution, to see stealthy objects at 100 mi.” D’Amico says. “You can defeat stealth with enough power. If stealth takes the signature [of an aircraft or missile] down a factor of 10, you have to increase the [sensor’s] power by a factor of 10.” Most current fighter-size radars have less than a megawatt of peak power. Detecting stealth would require tens of gigawatts, which is now impossible in fighter-size packages…
“We have shown everything we claimed with a laboratory testbed,” says Oved Zucker, director of photonics programs for BAE Systems’ advanced concepts facility here. “We are in the process of demonstrating total power substantially above 10 gigawatts, and we have plans to test [the system] further in an airborne mode…“
There’s no dearth of missions for HPM technology, including detecting and detonating improvised explosive devices, finding suicide bombers or hidden explosives, and attacking shoulder-fired anti-aircraft missiles…
“At one end, it can fry anything [electronic] that’s out there,” Zucker says. “The levels of EW extend from the sledgehammer to just making the [computer’s] brain a little bit befuddled so it can’t think for a moment. At a lower level, you can kill the detector of the other guy’s radar as part of the suppression of enemy air defenses. You don’t need much power because you’re going after the most sensitive part. You’re blinding the system.“
The level below that is to momentarily stop electronics from functioning. A radar will try to defend itself by using a chain of circuits to “blink,” and thereby shut out intruding signals. One method of exploitation is to do something during the blink. But if an intruding signal is fast enough, the radar can’t react in time to keep out the invader…
BAE researchers envision HPM pulse weapons that are powerful enough to disable a tank, a missile, perhaps a helicopter or aircraft, but at the same time are small and light enough to function as part of a microwave radar sensor designed into the skin of an aircraft.
I’m sure this beam combo is harder than AvWeek is making it out to be. But still, it’s an interesting concept.
Where are they getting all of these weapons from?
We need to secure the border over there. Anybody that is wants to drive into Iraq now, must be a terrorist. Read my blog and tell me what you think. I am ex military, but I do not agree that this war is going to well. Something better has to be done.
Lasers, masers, & more… Oh my!
.
What ever happened to the time when MacGyver could just take an ancient Mayan light pump, align a few rubies, & blow up a giant boulder.
.
Basically, they’ve created a device that could track stealthy targets (by bathing it in high powered radio waves) & create a focused EMP (via a controlled pulse), all with the same phased array. I’m gonna be pissed when they ‘accidentally’ knock out the internet.
.
I have to say my favorite part of Aviation Weeks article is near the end,“Unmanned designs are favored initially because of… the effects of HPM on humans…”. LOL! Yet they don’t define “effects on humans”. Maybe it’s be something like, ‘No more children for you!’.
.
If “More area means more power and gain.”, maybe they just found a new use for the B-52… They’ll keep that plane flying on a IV & a walker.
.
So as the duration of War moves closer to the speed of light. When do we start researching the technology to avoid the self-castration of humanity? I’m just asking.
Laser-Maser combo sounds great. I wounder if masers could be a substitute in case weather condition is a matter. In other words, the punch of electro-optical lasers versus punch of electro-magnetic masers through fogs and clouds. A different type of directed energy weapon will also force unfriendly countries to add on more counter measures for each, increasing cost of such weapons, more difficult for third world countries to purchase.
Laser (solid state), maser, and rail gun consume electricity, and storage of energy will matter, which may force to become more larger to gain space of storage of energy. In that term, I wonder if there is any chance of a comeback of ships that have the size of battle ships, and classified as battle ships. However, it may be different from older battle ships, which such battle ships using directed energy and rail gun would be running on nuclear power plant, and operated with less people onboard, and automation doing much of the job. These battle ship with multiple rail gun turrets will strike multiple targets hundreds of miles away, and target incoming anti-ship missiles and aircraft with lasers and masers. Meanwhile, if Zumwalt class would be the size enough for operating the rail gun, it may mean battle ships will have no return.
Eric and I were discussing this… we were splitting our skulls open trying to figure out what it means that the system “uses light to multiply the speed and power at which HPM [high-power microwave] pulses…”, or what they mean when they say that “To produce a large number of TEM antennas is sensible only if you can make each one sing to the same tune through this coherence [or synchronization] that comes from using [the speed of] light. That allows us to spread the source [of HPM pulse production] across the whole wing of an airplane.“
The conclusion we came to is that they’re probably talking about using photonics (circuitry that uses photons traveling through fiber optics in place of electrons traveling through wires) for the control circuitry of the microwave array, which would allow them to achieve better (read: faster) synchronization between the different cells of the array.
Note that what the BAE dude was saying, before the Av Week reporter so helpfully inserted his two cents, was simply that light is being used to achieve better coherence — which sounds to me like they’re talking about the control circuitry, not about some exotic power generation technology.
If we’re right, that sounds like a clever way to use next-generation technology (photonics) to solve a problem (synchronizing large arrays of microwave emitters) that has limited the effectiveness of sophisticated ASEA systems to date. But unless we’re reading this thing wrong (which is always possible) there doesn’t seem to be anything in what the BAE people (as opposed to the Av Week flack) are saying that would indicate that there is a laser weapon integrated into the package, or that lasers are being used to boost the power output of the HPM in any exotic way (which in itself sounds like it would violate the same law of physics as everyone’s old favorite, x-ray-driven isomeric transitions).
The ideal test platform would have been the USS Iowa or NJ or Missouri.
Even pierside for testing???
Be unique
Laser-Microwave Beam combo.
Nice.
Next ship base is the AEGIS types.
Best bets.
Or some carrier???
Or Amphib fwd deployed in Convoy force???
Has to be a Cruiser above size for Laser.
Or shore based fixed site.
& place Beam weapon in a ex KC135 type or 747 SP
777, 767 planes???
And when the players arrived at five times, but also to their stores to buy music to play all kinds of music (on the map that has a place to buy guitar). You can also buy Lord Of The Rings Gold to achieve your strong!
I would establish a strongest gang! I decide to buy hero coins on line.
Many people want to buy cheap gw gold, but they don
There are also some biblical powers such as turning others to salt or summoning a plague of locusts. Although when you begin the cheap Requiem Lant game you only know the relatively weak power of lightning, the few monsters you face in this part of Chaos will be relatively weak.
earn the 2moons dil and together play with friends, playing now I also feeling some tired, I do not know what things I persist in?
Because of the game, we understand with each other, unknowingly, play with you in the dofus already have more than one year, in the year we experience many things, together with you I was very happy, together with you, I earn many dofus kamas, I think we will together play forever, but I was wrong, until one day you tell me that you will left and said goodbye to me.
Like person calm down and slowly the feeling of thinking, I need thinking of by myself; the tears filling my eyes, my heart have nothing, I feel that o lose the all things, the world already give up me, the lingering shadow of shaking in my face, in order to play this game I spend money to buy the flyff penya, the BB again left me at the same time, same situation when I hard to get it, my angry can not use the words describe
Do not because Archlord cheap than ignore your favorite, If you ignore your favorite, you will regret a lifetime. In the end I hope that we will not hurt the parents
