ELSO (elektroninen sodankäynti) radiotaajuuksilla: radiotiedustelu, taajuushäirintä, EMP etc

Northrop Grumman has finished detailed performance testing on its Advanced Pulse Generator (APG), which represents the next technology evolution for the company's Combat Electromagnetic Environment Simulator (CEESIM) product that is used to test and validate the performance of electronic warfare equipment.

The APG utilizes high speed direct digital synthesizer (DDS) technology to generate radio frequency (RF) waveforms. This DDS-based capability offers industry-leading RF performance and brings significant advantages to the user, including higher modulation sample rates, wider bandwidth intrapulse modulation, higher precision and resolution, and reduced calibration time.

The capability also helps reduce RF part count, which leads to reduced cost and increased system reliability.

The APG is an affordable solution that keeps testing capability ahead of next generation receiver test requirements and can be included in new simulator designs or back-fit into any existing CEESIM simulators as an upgrade.

The APG is designed with open architecture modularity and flexibility, making it directly adaptable for use in laboratory, anechoic chamber and range applications.

"Our continued investment in the development of such leading-edge technologies as the Advanced Pulse Generator demonstrates our ability to meet our customers' need for next generation advanced threat capabilities and ensures our products are sustainable and adaptable to evolving requirements," said Joe Downie, site director of Northrop Grumman's Buffalo-based Amherst Systems business unit.

"The advanced waveform generation, when coupled with our advanced angle-of-arrival modeling and controlled by our state of the art graphical user interface, immediately transforms the CEESIM system into the most powerful, most advanced electronic warfare simulator available."

The Northrop Grumman CEESIM is an advanced technology simulator that generates complex dynamic electromagnetic environments to simulate true-to-war conditions. CEESIM provides angle-of-arrival radio frequency simulation techniques including phase, amplitude and time difference of arrival. The system includes an updated user interface that makes programming complex emitters more intuitive while allowing the operator to customize the interface to suit specific needs.

Northrop Grumman Amherst Systems produces deployable RF and infrared (IR) simulators for use in all elements of closed-loop operational support in the laboratory, anechoic chamber and on test and training ranges at military installations worldwide. The company's simulators test the world's most advanced electronic warfare warning systems, IR/ultraviolet missile approach sensors and radar-warning receivers and jamming systems.

All systems are scalable and can be customized to meet customer's specific needs on both the high and low end levels. These simulators verify for users that their sensors are working as effectively as possible and with the most accurate data load.

The Air Force is eying a new kind of wireless network.

Hoping to improve the way its planes communicate in hostile environments, the aerial branch of the U.S. Armed Forces is sharing $2.7 million with computer science researchers at the University at Buffalo who will spend the next four years developing software that can make wireless radios significantly smarter and more efficient. It’s called cognitive radio, and though the concept has been around for awhile, there are some signs that it’s getting ready for prime time, and it could be used to boost wireless networks well beyond the Air Force. Microsoft has tinkered with cognitive radio, and some think that Google could use it as a way of improving its self-driving cars.

In the 2001 action movie Ocean’s Eleven, criminals use an electromagnetic weapon to black out a portion of Las Vegas. Very futuristic, you may say, but the threat is real and growing.

The problem is growing because the technology available to attackers has improved even as the technology being attacked has become more vulnerable. Our infrastructure increasingly depends on closely integrated, high-speed electronic systems operating at low internal voltages. That means they can be laid low by short, sharp pulses high in voltage but low in energy—output that can now be generated by a machine the size of a suitcase, batteries included.

Electromagnetic (EM) attacks are not only possible—they are happening. One may be under way as you read this. Even so, you would probably never hear of it: These stories are typically hushed up, for the sake of security or the victims’ reputation. Occasionally, though, an incident comes to light.

In May 2012, for instance, the Korea Herald reported that over 500 aircraft flying in and out of South Korea’s Incheon and Gimpo airports reported GPS failures, as did hundreds of ships and fishing boats in the sea west of Incheon Airport. The source of the EM fields was traced to the North Korean city of Kaesong, about 50 kilometers north of Incheon. South Korean officials indicated that North Korea had imported truck-based jamming systems in 2010 that had the capability to jam GPS signals. These officials...

Tykkäsin varsinkin tästä osasta.

The aftermath was pretty unexpected. The Donald Cook retreated to the nearby Turkish harbour and left the Black Sea much before it was planned. The Russian media reported that the ship was completely unable to get a lock-on the airplane and the entire ordeal took over an hour. For such a long period the Su-24 simulated 12 attacks on the ship. The reports say that over 20 members of the ship’s crew filed the decommission request. The US side firmly discarded such allegations but the fact is that something unexpected happened.

Todennäköisesti ihan normaali saatto/stand-off häirintälaite. Samanlaisia on EA-6/18G koneissa amerikkalaisilla. Tekevät juuri sitä mihin ne on tarkoitettuihin.
 
Kuulin radiosta yhtenä päivänä että viestikoelaitoksen uusi SIGINT-Casa myöhästyy operatiivisesta käytöstä hieman teknisten ongelmien vuoksi. Onko kellään tietoa asiasta?

Noita rottia on muuten ihka oikeasti yritetty kouluttaa. Ei tosin Suomessa eikä suomalaisilla tiettävästi ole niihin aikeita panostaa tai sellaisia hankkia. Koulutettujen "rottien" kanssa on sitten eri asia.

Muistan lukeeni saksalaisten panssarijoukkojen kärsineen jossain määrin, kun jyrsijät (hiiret?) olivat nakerrelleet venäjän maalla panssarivaunujen johtoja.
 
LAHDESSA MATKAILEVA NÄHTÄVYYS ???
Lukekaa s.5 LINKKI

Uutisia ja muuta uutta asiaa muualta Venäläinen ”radioauto” tullut taas parkkiin!

Muutama kuukausi sitten kerroimme Lahden rautatieaseman pysäköintipaikalla olleesta venäläisestä radioautosta. Auto oli ollut parkissa puolisen vuotta mutta katosi
seuraavana päivänä, kun eräälle iltapäivälehdelle annettiin vihje.

Yllätys, yllätys …. radioauto on palannut parkkiin!
Entistä ehompana. Satelliittilautanen on puhdistettu ja takakattoboxiin menee ainakin kaksi noin 30 mm koaksiaalikaapelia! Lisäksi muutama
paikalla käynyt on ilmoittanut, että mikäli radioautoa lähestyy, lähelle pysäköidystä maasturista nousee pari nahkatakkista miestä ….
Todennäköistä tietenkin varmaan on, että kyseessä on vain viaton urheilulääketieteeseen kuuluvan auton pysäköinti odottamaan seuraavia
Salpausselän kisoja ….

Onko nuo tosissaan? Mitä varten tuollainen radioauto voisi olla? Tuotahan voisi käydä vilkaisemassa.
