Which early warning radar is stronger?The detection range of the United States can reach 4,000 kilometers, and Russia's is even more outrageous, reaching 6,000 kilometers
On the east and west coasts of the United States stand two tall buildings, which are incompatible with the surrounding dwellings, like aliens built on Earth, and like the sacrificial altars left by the Mayans. The four sides of the building are covered with more than 2,000 metal blocks, and friends who are familiar with military equipment can see at a glance that this is actually an early warning radar.
In the 70s of the last century, in response to the strategic missile attacks of the Soviet Union, the United States built such large radars on both the east and west coasts, named them"Paving claws".The average power of the pave claw radar is 145 kilowatts, it is fully turned on 24 hours a day, it takes more than 2,000 kilowatts of electricity a day, it takes about 6 seconds to scan once, and the detection range of missiles and aircraft with a radar reflection area of 10 square meters is 4,800 kilometers.
Judging from the data, this pave claw radar has lagged behind, although its detection range is long, butThe radar reflection area of China's J-20 and Dongfeng-41 is much less than 10 square meters, this large radar has nothing to do with them. Because the power is too large when it is turned on, the cancer rate of the surrounding residents is significantly higher than that in other areas.
Although the early warning radar releases electromagnetic waves, which are no different from the signals of the 5G communication base stations we use, the electromagnetic wave frequency of this radar is very high, reaching 450 megahertz, and the ultra-high frequency and ultra-large power will inevitably affect the human body. In 2003, the United States has shut down the local paving claws, and second-hand goods are exported to Taiwan Province.
Russia's radar of the same type should be the first in the world, all of which are old antiques left over from the Soviet Union, and the Soviet Union built several radar arrays during the Cold War, the largest of which is called"Duga".The detection range of the Duga radar reaches 6000 km and the power is 1000 kW.
It is said that once the Duga radar is turned on, the shortwave signal communication of the whole of Europe will be jammed, which sounds scary, but it has no effect. Because current military communications do not use short waves, such a large early warning radar cannot detect stealth fighters and stealth missiles, because they are too large and have been kicked out of the air defense system by various countries.
In fact, our country has also installed such an early warning radar, and the PLA is very good at saving money, and the United States and Russia directly build the bracket of the early warning radar, while our army puts the radar array on the hillside, and there is no need to build an additional radar station, and you can live in a few caves. Such radars can still be seen in China's coastal provinces such as Shandong and Fujian, but most of them have been dismantled, and it is said that these radars can roast nearby birds when they are turned on, which shows how high their power is.
At present, only China has this kind of super-large radar in the worldIn 2022, the People's Liberation Army (PLA) announced a large early warning radar, which is significantly smaller than the entire radar column adapted to China, the United States and Russia in the last century, and the power has also been reduced a lot. Despite this, it reaches a height of 40 meters and a detection range of 4,000 kilometers.
It is worth noting that this detection range refers to the detection range of ** aircraft such as F35 and B2, which uses P-band electromagnetic wave detection, and can be matched facing the East China Sea.
F35 fighters and cruise missiles on the first and second island chains were detected, and every move of the aircraft flying throughout the territory of Japan was fully visible.
In fact, this kind of ground-based fixed early warning radar is no longer the mainstream of the development of various countries, and now the major countries have begun to focus on airborne radar systems.
There are two main types of airborne radars, one is aircraft and the other is ships. But there are alternativesFor example, Russia's new-generation main battle tank T14 Armata is equipped with an active phased array radar that is only available on aircraft, with a detection range of 100 kilometers. I don't know what the Great Russia thinks, the brain circuit is very clear, what is the use of such a good radar for a tank?Can armor-piercing shells shoot 100 km, the battlefield perception of the T14 is already excessive.
At present, China and the United States are mainly focusing on early warning aircraft in the field of early warning radar, and although the radar power of early warning aircraft is not as high as that of large radars on the ground, its detection range is very long. Because ground-based radars will be affected by obstacles such as mountains and rivers, buildings, and at the same time, they must be built on high mountains, but no matter how high the mountains are, no early warning aircraft can fly high, and at present, only China and the United States can independently manufacture early warning aircraft in the world.
China's early warning aircraft have left the United States far behind, and the Chinese Air Force used the J-20 to expel the F35 last yearAir Police 500A spokesman for the US side said that he was impressed by China's AWACS aircraft. The U.S. military is now in a hurry to procure the most advanced of its ownE7 AWACS, and our country'sAir Police 3000The R&D project has been finalized and the first flight is expected to take place this year.
Now China's early warning aircraft can be described as unique in the world, there is no big disc on the back of the aircraft, and the radar array uses common technology to cling to the fuselage, and the appearance looks no different from the ordinary Y-20.
It can be used as a visual metaphor to illustrate the generation gap between China, the United States and Russia AWACS, China's air police 3000 is like an iPhone4 phablet, while the United States' E7 is like a big brother, Russia is the poorest, and they are still using BB machines.
