Super Weapon Swap System

This meter wave radar is very difficult. However, when the Han country found that there was a great threat above its head, the 14 most famous institutes in the Han country began their research and development in this field. After years of efforts, they finally produced this meter wave phased array radar that was considered impossible by the West.

For example, the most representative is the jy-26 of the Han Dynasty. The antenna array of this radar is so large that it is unimaginable. It is placed on a flat trailer. After the radar array is erected, it is more than ten meters high, covered with cylindrical components. It looks like iron fist bazookas are stuffed in. The dense array, Enough to make people with dense phobia get goose bumps all over.

The performance of this radar is also quite powerful. It adopts advanced technologies such as active phased array, sparse matrix and super-resolution, which improves the sensitivity, expands the coverage airspace, and the search distance exceeds 500 kilometers. This radar is tailored for stealth aircraft. When the stealth aircraft of Eagle country began to become a threat to Han country, Han will never wait to die. We must come up with corresponding solutions.

Not only the Han Dynasty, but after that era, other countries began to study the ways to combat stealth aircraft, such as the meter wave comprehensive pulse aperture radar of the chicken country, the meter wave circular array radar of the Hans country, the "East" - E and "sky" - y radars of the great Mao country, all of which are representative meter wave three-dimensional radars with good performance.

Among them, due to the confrontation of the cold war, Xiong Guo's research is the most advanced. After all, Xiong Guo has rich experience in the development and use of meter wave radar.

When facing the threat of stealth aircraft, they developed a series of new three-dimensional radars, such as the most advanced "sky" - y meter wave radar. The mobile meter wave three coordinate scheme is adopted, which has the functions of ranging and altimetry. It can track all kinds of air targets, even small hypersonic ballistic missiles and small stealth vehicles at a distance of 600 kilometers.

Han is also unwilling to fall behind. By 2020, Han's meter wave radar technology is already at the world advanced level.

Now, the contradiction is mutual. Our side should develop stealth aircraft and break through each other's airspace at any time. Of course, our side should also have protection ability to find intruded stealth aircraft. Of course, stealth and anti stealth will be our top secret and will never leak out. After all, this is a key issue related to the victory or defeat of future wars.

Qin Guan has now pointed out the direction. On land, you don't have to worry about the size and weight, so you can make this large meter wave phased array radar. Of course, in order to prevent being hit by the enemy in the first round during the war, your side needs to make these radars into mobile deployment radars. During the war, Radar is also the most important target of the other party's attack.

The development of this radar must be very difficult. Even with the information provided by Qin Guan, it will take several years. However, once it is studied, it will certainly stand at the highest point of anti stealth technology.

As for the stealth aircraft, how to improve it, there is no hiding in front of the meter wave radar. The changes of its various shapes are invalid in front of the meter wave radar, because what the meter wave radar sees is just a point and will not see all aspects of it.

Now, Qin Guan has put forward the first important scheme, which is to vigorously develop modern meter wave radar technology. This is definitely not the old radar, but the digital radar improved by modern electronic technology, or even radar networking.

Qin Guan opened an idea for everyone. Of course, this is one of them.

"Another idea of anti stealth aircraft is to use passive radar." Qin Guan threw out a new term. If the meter wave radar in front of us can still be clear, it really looks like a Book of heaven behind us.

In fact, the West has begun to study passive radar, but they all study it under the condition of high confidentiality. In China, no one has been involved in this project for the time being.

"Passive radar is the opposite of active radar. Our usual radar transmits radar waves and then receives radar waves, so that we can detect the target." Qin Guan said: "while passive radar, we don't transmit electromagnetic waves ourselves, but only receive them."

"If you don't launch, how do you receive it? Whose?" someone asked.

You know, the basic principle of radar is radio locator, transmitting signal, target reflected signal, receiving, calculating distance according to time difference, and calculating direction according to the rotation of radar antenna. If nothing is transmitted, how can you know the target?

"There are two situations. Some targets radiate electromagnetic waves themselves." Qin Guan said, "for example, military targets may not turn on the radar, but their communication stations, transponders and navigators radiate electromagnetic waves and can be located based on these electromagnetic signals."

Qin Guan opened a new world again.

Even if the radar is not turned on, the radio of an ordinary aircraft must be turned on. Even if the radio is in the passive receiving state all the time, the transponder must be turned on. Otherwise, it may be hit by friendly forces by mistake. Almost no one will turn off this thing. Even if the response mechanism falls off, it has to navigate by itself? For example, its altitude is measured by altimetry radar. In short, there must be electromagnetic radiation. According to these, we can find the target.

"If the target doesn't radiate any electromagnetic waves, we can do it, because the sky around us is full of electromagnetic waves all the time," Qin Guan said.

In later generations, communication companies are sometimes very helpless. Building a base station in the residential building of the community was originally convenient for the people of the whole community, but some people quit. No, there is radiation, so they must be removed for us!

They are very concerned about radiation. Even when their wife is pregnant, they don't even want to go through a security gate. They also want to have a special channel for pregnant women. Of course, what kind of radiation protection clothing is also the most expensive thing to buy. It costs thousands of yuan, and they never blink.

They hate this kind of base station even more and must be removed.

Then, they moved away, followed by another statement, no, our mobile phone signal is not good, we have to complain!

In fact, if you want to have no radiation in their mouth, unless you go to the primitive society, radiation is everywhere in the whole world. Sunlight is radiation. You can move the mobile communication base station away. Can you turn off all radio stations, television stations and everyone's mobile phones?

Even you have to stop all cars. Gasoline cars are ignited with spark plugs. There will be strong electromagnetic radiation when they are ignited.

The whole radiation is everywhere.

This also provides a stage for passive radar.
