According to reliable sources, the mainland People's Liberation Army electronic warfare exercise held in the Yellow Sea, held in the past PLA electronic warfare exercise, not an election in the inland areas is selected in the East China Sea, this will be moved north to the Yellow Sea, it was judged that the mainland's exercise goals , is the U.S. intelligence ship lock.
　　
PLA latest electronic warfare aircraft electrical radius of 150 km, and a body with a big plate of the aircraft, it is only recently confirmed by the Western intelligence agencies for the first time. Leased by China to the Russian early warning aircraft A50 electronic warfare, this early warning aircraft can simultaneously track 50 air targets. Now both fighters are also power in the Yellow Sea over the year in PLA electronic warfare exercises.
　　
Sources said that the PLA exercises held in the Yellow Sea deliberate choice, it is understood in addition to Taiwan in order to avoid outside stimuli, but also because the United States in the last 3 months to send a large number of spy planes and ships, monitoring North Korea in the Yellow Sea, so the PLA exercises in this area , there are challenges means gathering and electronic parameters.

　　
The mainland's electronic warfare exercises, most likely to report being in 2002 the PLA electronic warfare counter-revenge. At that time the U.S. 7th Fleet exercises off the coast of Okinawa, Japan, the PLA warships have been electronic interference, the rumor that the U.S. military power electronic countermeasures aircraft immediately, resulting in the mainland coast of the PLA in northern Fujian Telecom paralysis. It is understood that, A-50 nicknamed the "backbone", which is known to the world during the war in Chechnya. It was April 22, 1996 at 4 o'clock, A-50 early warning aircraft, intercepted between Dudayev and other mobile communications, and then with the help of global positioning system to accurately measure the location of the Dudayev coordinates. A few minutes later, A-50 AWACS command of the Russian Air Force Su -25 40 km away from the target aircraft fired two local DAB-1200 anti-radiation missile, the satellite will be the ongoing call Dudayev killed.

A-50 equipped with "bumblebee" integrated power electronic systems, including coordinate pulse Doppler radar, electronic warfare surveillance antenna, IFF systems, and digital anti-jamming communications equipment. A-50 is powered by four D-30K turbofans, a single maximum power of 120 kW. Its performance with the U.S. E-3A "Sentry" AWACS similar. Its maximum speed of 850 km / h, service ceiling 12,000 m, maximum range of 5,500 km. It to 700 ~ 750 km / hour speed of 9,000 meters to 10,000 meters altitude cruise 7.5 hours, 1,000 km away from the base in place to patrol four hours. It is also a way to extend the refueling blank time. A-50 targets in the search for one's own aircraft, the distance and guide number than the U.S. E-3A, but it is the ability to identify low-altitude target than E-3A.
　　
A-50 have improved greatly in recent years. Improved "backbone" called A-50U. Main improvement is the use of the whole nine meters in diameter rotating radome, coordinate pulse Doppler radar, computer systems and digital subsystems to enhance information processing, target identification, radio communications (including satellite communications) and precise navigation and other functions, Therefore the objective of detecting and tracking the number of target distance were increased, enhancing the ability of the flying targets and anti-jamming capabilities for early warning. A-50U "backbone" also has the look down capability, can be detected in the background clutter of long-range bombers and cruise missiles flying targets. It uses a lower vertical tail to improve flight stability, and its take-off weight of 210 tons, carrying more fuel, more distant operations, patrol time from four hours to six hours. It can be the enemy of radio electronic warfare weapons and tracking to determine. The original A-50 aircraft in the presence of strong noise and ultra-high frequency radiation has also been overcome. According to reliable sources, the mainland People's Liberation Army electronic warfare exercise held in the Yellow Sea, held in the past PLA electronic warfare exercise, not a choice in the interior, that is, the election in the East China Sea will be moving north to the Yellow Sea, it was judged that the mainland's exercise objectives, U.S. intelligence ship is locked.
