The BMP-3 has also an ability to carry Shtora electro-optical jammer that disrupts semiautomatic command to line of sight ( SACLOS ) antitank guided missiles, laser rangefinders and target designators.

The required referees are a head referee, who oversees the running of the entire game and has final say in any disputes, and who doubles as an inside pack referee, following along side the main pack of skaters from inside the track and issuing and enforcing penalties for fouls or infringements of the rules ; and two jammer referees who follow the two point-scoring players known as jammers.

Merc has triggered a jammer so that he and Hal can escape IVR, and they both wake up in their beds in the school.

Believed to have been used as electronic jammer aircraft in " Operation El Dorado Canyon ".

Jamming is problematic to radar since the jamming signal only needs to travel one way ( from the jammer to the radar receiver ) whereas the radar echoes travel two ways ( radar-target-radar ) and are therefore significantly reduced in power by the time they return to the radar receiver.

Jammers therefore can be much less powerful than their jammed radars and still effectively mask targets along the line of sight from the jammer to the radar ( mainlobe jamming ).

If jamming is used continually, it can be extremely difficult for a missile to acquire the target, locking on to the much larger return from the jammer, with the operator unlikely noticing the difference without a radar screen to see the return.

* Mobile phone jammer, an instrument used to prevent cellular phones from receiving signals from base stations.

Gee was highly susceptible to jamming since all the Germans had to do was radiate surplus pulses that made it impossible to determine which was a real signal from the slave and which was being broadcast from a jammer.

The jammers start from the " jammer line ," a second starting line 30 feet behind the pivot line.

Aside from power loss to the jammer, radar receivers can also benefit from using two or more antennas of differing polarization and comparing the signals received on each.

* Pulse jamming produces noise pulses with period depending on radar mast rotation speed thus creating blocked sectors from directions other that the jammer making it harder to discover the jammer location.

By analysing received signal strength from side and backlobes and thus getting radar antennae radiation pattern false targets can be created to directions other than one where the jammer is coming from.

A mobile phone jammer is an instrument used to prevent cellular phones from receiving signals from base stations.

Less energy is required to disrupt signal from tower to mobile phone, than the signal from mobile phone to the tower ( also called base station ), because the base station is located at larger distance from the jammer than the mobile phone and that is why the signal from the tower is not as strong.

A Charm City Roller Girls | Charm City All Stars ( Baltimore, Maryland ) blocker vs. a Rhode Island Riveter ( Providence, Rhode Island ) jammer

Mainlobe jamming can generally only be reduced by narrowing the mainlobe solid angle and cannot fully be eliminated when directly facing a jammer which uses the same frequency and polarization as the radar.

* Install active laser jammer or radar jammer devices which actively transmit signals that interfere with the measuring device.

Perhaps most impressive of all was AIL's Type MAS jammer which employed sophisticated signals to defeat the Kehl transmission and to take over command of the Hs 293, steering it into the sea via a sequence of right-turn commands.

Another aspect of passive anti-radiation homing is the " home on jam " mode which, when installed, allows a radar-guided missile to home in on the jammer of the target aircraft if the primary seeker is jammed by the electronic countermeasures of the target aircraft

A GPS spoofing attack begins by broadcasting a slightly more powerful signal that produces the correct position, and then slowly deviates away towards the position desired by the spoofer, because moving too quickly will cause the receiver to lose signal lock altogether, at which point the spoofer works only as a jammer.

Two electro-optical / infrared ( IR ) " dazzlers " interface station one each mounted to the left and right of the main gun, which includes an infrared jammer, modulator, and control panel.

Game play consists of a series of short matchups (" jams ") in which both teams designate a scoring player ( the " jammer ") who scores points by lapping members of the opposing team.

Drozd was followed by Shtora in the late 1980s, which used an electro-magnetic jammer to confuse inbound enemy anti-tank missiles and rockets.

In perhaps the first example of ECCM, the Germans increased their radio transmitter power in an attempt to ' burn through ' or override the British jamming, which by necessity of the jammer being airborne or further away produced weaker signals.

* Tuning circuit — Controls the frequency at which the jammer broadcasts its signal by sending a particular voltage to the oscillator

Shtora-1 is an electro-optical jammer that disrupts semiautomatic command to line of sight ( SACLOS ) antitank guided missiles, laser rangefinders and target designators.

After the initial pass through the pack, each jammer scores a point every time he or she laps a member of the opposing team ( including the jammer who is not lead ).

Using or possessing a radar detector or jammer is illegal in certain countries, and it may result in fines, seizure of the device, or both.

This method is also useful against barrage jamming, in that it forces the jammer to spread its jamming power across multiple frequencies in the jammed system's frequency range, reducing its power in the actual frequency used by the equipment at any one time.

Therefore, jamming can be seen in directions other than where the jammer is located.

* Barrage jamming is the jamming of multiple frequencies at once by a single jammer.

The advantage is that multiple frequencies can be jammed simultaneously ; however, the jamming effect can be limited because this requires the jammer to spread its full power between these frequencies, as the number of frequencies covered increases the less effectively each is jammed.

If each radar pulse is uniquely coded it is not possible to create targets to directions other than the direction of the jammer

Modern jammers can track a predictable frequency change, so the more random the frequency change, the more likely it is to counter the jammer.

* Cloaking the outgoing signal with random noise makes it more difficult for a jammer to figure out the frequency that a radar is operating on.

The jammer could be listening, and if they know that a certain technique is effective, they could direct more jamming assets to employ this method.

* Best indicator of jamming effectiveness to the jammer is countermeasures taken by operator.

Thus, rather than being understood only as a media prankster and culture jammer, Luther Blissett became a positive mythic figure that was supposed to embody the very process of community and cross-media storytelling.

He was famous as a peerless jammer and held his own against Charlie Parker.

Radar fields rendered cloaked units detectable ; a radar jammer could make said units undetectable until the radar jammer itself was destroyed.

The infrared jammer, the TShU1-7 EOCMDAS, jams the semiautomatic command to line of sight ( SACLOS ) guidance system of some anti-tank guided missiles.

The information will allow the British to field an operational jammer to counter the radar in late April 1943.

The teams attempt to assist their own jammer while hindering the opposing jammer — in effect, playing both offense and defense simultaneously.

Each team designates a scoring player ( the " jammer "); the other four members are " blockers.
