Phase array radar! Of course John has heard that general radar beam scanning is achieved by the rotation of radar antennas, which is called mechanical scanning. For example, the current Hunter Early Warning Machine is equipped with a mechanically scanned radar antenna in front and back, while the phased array radar has the antenna that remains motionless and uses a phase shifter to control the direction change of the radar beam to scan and discover the target. This method is called electrical scanning.

Nowadays, phased array radar has been used in some applications, such as the huge American paving claw radar, which is used to detect intercontinental ballistic missiles, and can have a detection distance of 3,000 kilometers.

However, phased array radar also has its shortcomings, such as complex equipment and high cost. Moreover, due to the huge waveguide, it cannot be equipped on fighter jets. The phased array radar at this time is mainly used for ground long-range early warning.

"Of course I have heard that our British A-3D radar uses phased array technology." John said. After saying that, he suddenly thought: "His Excellency Kusai, are you talking about moving the phased array radar to our plane?"

"Yes," Kusai replied: "In the future, advanced early warning aircraft will not be fully equipped with large plates. Phased array radar antennas can also be arranged on the front and sides of the aircraft to achieve all-round monitoring of the target."

When John heard this, his eyes shone brightly. Yes, if that was the case, there would be no need to use the American method at all. It would have a great impact on the aerodynamic layout of the aircraft. However, if you do this, can the phased array radar antenna be moved onto the aircraft? After all, that kind of antenna is still too bulky.

"With the development of microsemiconductor technology, small units that can emit/receive electromagnetic waves in gallium arsenide chips will be developed in the future. Each unit is a t/r component, which can achieve the miniaturization of active phased array radars." Kusai said: "If you are interested, we can conduct research together in Iraq."

A very small transmitting and receiving component? John didn't believe it and shook his head: "We are here to set up hunting fans. These pre-research projects need to be approved by the company."

Kusai knew that what he said would not become a reality in ten years. Israel's Felcon early warning aircraft first flew in 1993. It would be a bit too early to say this now. If I had not come from later generations, I would probably never believe those nearly science fiction technologies in later generations.

Technology will change the world. Although Iraq has oil under its land, if you want to become a giant in the future world, you need to start now and seize the commanding heights of electronic technology!

"Chief Engineer John, I hope that early warning aircraft like ours can be put into service as soon as possible," said Kusai.

"Yes. We will set this early warning aircraft as soon as possible." John said. After these test flights, he knew that all the problems were being solved one by one, and this early warning aircraft would soon enter the army.

"Please pay attention to maintaining posture, especially the posture that falls for the moment." The instructor of the 67th Airborne Regiment conducted strict training for the newly joined soldiers.

Although those who were absorbed were all Iraqi soldiers with rich combat experience. They were majestic, tenacious and superb combat skills, none of them relaxed at the training in front of them, although this was just a two-meter-high jumping platform.

Paratroopers descended from the sky and looked very beautiful, but every paratrooper had to undergo rigorous training, for example, now, jumping from these two-meter-high jumping platforms requires two thousand times a day! This is to train the ability of legs to adapt to ground impacts.

Skydiving is a high-risk action. If you have not been trained, even if the parachute can be opened smoothly and landed on the ground, it will sprain your foot or even break your leg at the moment of landing due to the incorrect posture of your foot.

Repeated exercises every day are to make your feet adaptable.

On the other side, on the huge field, other paratroopers were sorting out their umbrellas.

As airborne soldiers, parachutes are their unique equipment. Each paratrooper cannot jump an umbrella only once in his life. Except for the battle, each paratrooper cannot discard the used parachutes. Therefore, paratroopers have a task that other troops do not have: sorting out umbrella tools.

There were nearly thousands of umbrellas neatly arranged in the playground: the unchanging white and blue colors spread the parachutes on the ground, and the comrades formed a cooperating master and deputy, ran around the mat, carefully sorted out the parachutes, folded the umbrella clothes, and the umbrella clothes that were shaken one after another, forming waves of umbrellas.

They then put the folded umbrella suit into the slender umbrella suit cover, put the 10-meter-long 30-strand parapet rope into the rope cover, fold the umbrella to complete the packaging.

All this seems to be a work done by women, but they are doing very carefully now, because if something goes wrong and the parachute cannot be opened in the sky, it means death for them.

Airborne troops are the most casualty group! Their first casualty is the dangerous parachuting.

For other Iraqi Army elites who are already proficient in ordinary combat skills, the focus of their quick success is parachute.

In addition to practicing platform jumping and umbrella stacking, they also need to practice how to stand on bumpy planes with heavy parachutes and maintain the correct off-aircraft posture. They also need to conduct ring training and practice maintaining landing postures from high altitudes. Iraqi paratroopers are growing rapidly.

Paratroopers can still withstand these basic training, but memorizing the special air situation will make the paratroopers feel a little scared while being overwhelmed.

"What should I do if the main umbrella is not opened?" Looking at a soldier who had just jumped off the two-meter-high skydiving platform, the instructor would suddenly have such a special incident.

"Open the backup umbrella!" The soldier immediately used his right hand holding his abdomen to make a vigorous push and pull, and then thrust his abdomen, which means that the backup umbrella has been pulled open.

"What if there is another umbrella in the air?" the instructor then asked the next soldier.

The soldier was stunned and didn't react, "Then let's land with him."

"Then both of you will fall to death together!" The instructor cursed: "These are all issues related to your life. Don't implicate your comrades who are parachuting with you!"

The soldier immediately blushed. It is not scary to die, but if he drags down his comrades, they will never forgive him. Even if he doesn’t sleep, he must remember all these things!

The special situation in the air is a very terrifying thing. So many people jumped off the plane, and all kinds of situations may occur. Two umbrellas are wrapped around each other and hung on the branches. The sudden crosswind appears... Only by dealing with it calmly and decisively can these hidden dangers be eliminated.

Although Abed, the commander of the 67th Airborne Regiment, did not know his exact mission, according to the news from above, Abed also judged that what they were about to face was a difficult test, so he did not dare to relax at all and kept working hard to make this army have the conditions for paratroopers in a short period of time.

In addition to the paratroopers, more than twenty helicopter units assigned to them have arrived. Some soldiers of the airborne regiment have begun to practice the tactics of landing from the Mi-24 helicopter.

Abed is still very welcome to the armed helicopters he equipped with. In this way, he does not need to call for support from above. He can solve the problem of a small number of air defense firepower on the ground by himself.

The only thing that made Abed a little dissatisfied was that the large transport aircraft that could carry his troops had not arrived yet. Now, he only had a small transport aircraft that could let the guys under him feel the feeling of flying into the sky. If the paratroopers didn't even skip an umbrella, they would let them fight. Abed might close his eyes and think about the ending.

Just as the 67th Airborne Regiment was conducting training at the garrison, the army mobilization on the front line of the battlefield between Iran and Iran began to proceed quietly.

After taking Hamadan, the main force of the Northern Group originally wanted to continue to completely occupy the Central Province, especially to the south, Arak, the capital of the Central Province. But now, the direction of the main attack has changed. We need to boldly intersperse through the Central Province and head directly to the small town to the east. Therefore, Iraq's two most powerful armored forces, the First Armored Division and the Fourth Armored Division of the Republic Guard, all gathered in Hamadan.

The Fourth Armored Division will go directly eastward, causing a situation of attacking important eastern cities. At the same time, the First Armored Division will be on standby in the north of Hamadan and ready to rush to Tehran at any time.

As they have crossed the mountains, the most powerful armored forces among these two Iraqi troops are ready to usher in the most important victory they have built.

They were not alone, they would be protected by the air force, and behind them, two mechanized infantry divisions would arrive later.

In Bakhtaram, the Iranian National Liberation Army was also undergoing high-intensity training nervously. Iraqi instructors completely treated them as regular troops, even elite troops, and got up from bed every day and finally crawled back to bed like dead dogs.

However, the treatment of female soldiers is much better, and the training intensity they receive is lower, which makes the leader of the female soldiers Mariana Rajavi a little dissatisfied and asks for more training intensity several times.

Unconsciously, Iraq was already secretly accumulating strength, hoping to complete a miracle battle in military history and take over Iran's capital with a thunderous blow.

At this time, the world's eyes were still focused on the back garden of the United States, on the Caribbean Sea.
