Electronic Warfare Analysis of Army SINCGARS Radios Operation tempo in cyber and electronic warfare can be described by the OODA (Observe Orient Decision Action) loop decision making process (Pace). The steps occupy a logical order of electronic attack or defense. First, a particular electromagnetic characteristic is observed by either human or electronic operators. For example, a spike in a frequency known to be used by the enemy, indicating a potential target for electronic attack, or a sudden increase in noise on friendly systems which could indicate jamming by an adversary. Orientation is the allocation of resources to either exploit or counter the observed characteristic, such as reconfiguring analog or digital tuners, clocks, or filters …show more content…
The system operates in the VHF band of 30 to 88 MHz, segmented into 2320 25 kHz channels. SINCGARS radios are also able to operate in a frequency hopping mode, with a rate of 111 hops per second along its 58 MHz bandwidth, and holding all other factors constant, this gives a static OODA loop operational tempo of 9 ms. The typical radio has a worst-case sensitivity of -110 dBm, as given by the manufacturer, with a typical value of -116 to -120 dBm. Adjacent channel isolation is 45 dB, so interference will be ignored in the analysis …show more content…
This would render conversation intelligible, as every second of transmission would include a static burst that would cause information to be lost. In mathematical terms, this means the 25 kHz wide jamming signal must sweep through the entire bandwidth every second. With 2320 channels, this yields a required tempo for the jammer as: 0.43 ms. The required operational tempo to effectively jam the SINCGARS radio is much higher than operational tempo required to frequency hop. This can be explained by looking at the bandwidth cost for the hopped radio and the swept jammer. The radio hops 111 times per second, with each hop being a distinct channel, but has 2320 channels to choose from. Each second only uses a small part of the total bandwidth, specifically 2.7 MHz out of an available 58 MHz. In contrast, the jammer is blind to the hop pattern, and must sweep over the entire 58 MHz once a second to have a chance of interrupting at least one
IO seeks to integrate and synchronize information related capabilities with maneuver to target the enemy’s decision-making cycle
Everybody inside of the 28.120 to 28.123 MHz ten meter passband will be uplinked and heard on the 435.350 MHz downlink.
In comparison to other radio systems, multi-site trunked radio systems provide the best coverage. Multi-site
Starting the third week of CIS610 Information Warfare Class it I had a very good idea of what was expected of me as a student in this class. I was able to determine this based on the quick grading and excellent feedback provided on each of my assignments in week one and two. This allowed me to use this information to improve my work to better meet the expectation of the teacher. Along with this, going into the third week of class I felt as if I had gotten into a schedule which would work best for ensuring the completion of my assignments in an organized and timely fashion.
The Shure system has easy set up features and has no interferences whatsoever. The system is more than suitable for a church and is the best option when it comes to wireless mics.
Project Abstract: The following is a discussion of the application of Army Signals Intelligence (SIGINT) capabilities which are employed in order to enhance the targeting and effects of the Ar-my’s Cyber Electromagnetic Activities (CEMA) Sections. The aim is to address how the assimila-tion of assets, programs, and capabilities currently available to the Army SIGINT Community by the Army CEMA Sections could significantly enhance their ability to conduct and execute the war-time mission, thereby enhancing the commanders’ understanding of the enemy’s tactical use of the electromagnetic spectrum (EMS). This, in effect, would also reduce the time invested in acquiring EMS specific information and increase the precision and execution of Electronic Attack (EA), Elec-tronic Protect (EP), and Electronic Warfare Support (ES) by strengthening and
even when devices are not within line of sight. The range of each radio is approximately 10 m, but can be
It also operates on both 2.4 and 5GHz bands. (For a better understanding of what this means check out this review of this affordable Wi-Fi router.) Starry Station is available from Amazon on February 5th.
Amateur Radio, better known as “Ham Radio”, is a hi-tech international hobby that exists for personal two-way communications, experimentation, and public service that is greatly enjoyed by people from all walks of life and all corners of the world. Ham radio has been referred to as “Old school” Communications since it has been around for over one hundred years and still going strong. It has also been compared by many as the Facebook, Twitter and the first wireless phone from the old days.
There are many things that are considered Military Technology, such as any advancement that is adaptable and changeable to make a product or an organization of people stronger. Military Technology can also be for the worse, as in killing ranges of animals or people physically modifying themselves to be better than the ones their trying to overrule.
"It's called frequency hopping," I said, "and it can help you guide a torpedo, which uses a transmitter and a receiver to make the frequencies jump at the same time by a radio signal."
The problems include environmental noise and RF signal reflections that give rise to multipath fading--variations in RF signal level due to signal reflections. The improved robustness of digital radio promises to remedy this, delivering near-CD sound for most listening conditions.
In the modern life style there are numerous organisations are spending enterprise content management (ECM) systems, in directive to achieve multifarious data related to the association. This material wants to be sheltered from illegal workers. The main determination of this study reports is to examine nearly to the security tasks confronted by petty and large scale business. The primary part of this study contains of finding present and related on ECM security. At that moment, it 's essential to thru on but the automated conflict project and content management systems are entirely different from data structures. As associate degree electronic warfare system might handle each structured and unstructured information, there are a great diverge of possible security problems electronic warfare systems give business connected edges like availability, accurate document organisation, advanced growth organization. On the opposite hand, electronic warfare systems are susceptible to security fears beside those groups and their papers. The assignment review for additionally shields of the numerous categories of security attacks and a few of the defensive actions.
The branches of the military, for a couple generations, have always been the Army, Navy, Air force, Marine Corps, and the Coast Guard; however, in an ever evolving digital world, the notion that outer space would be the next military front is being rapidly replaced by the idea that cyber space will be the next arms race. The United States has been defending attacks on their infrastructure day after day, night after night, when one hacker on one side of the world sleeps, another takes their place to attempt to compromise the US government. The motives may range from a political ‘hacktivist’ trying to prove a point, to an economic spy, trying to gain a competitive edge on its more upstart rivals, to an attempt to control the United States
The key features of CR system is that it senses the electromagnetic environment to use their operation and dynamically vary its radio operating parameters. With the likely transition of radio communications from static to dynamic spectrum access in the near future, spectrum sensing has become an interesting area of research. Even though many signal detection methods have a long history, economical implementations of consumer devices employing spectrum sensing are still missing. In this research an overview of current state-of-the-art spectrum sensing methods, limited to the binary decision of channel occupancy is presented. Existing methods are categorized into energy detector, cyclostationary and matched filter methods. A concise introduction and theoretical background of various spectrum sensing methods based on their operation, and drawbacks.
