Live broadcast of my blind date with Miss Dai, sister Zhou was arrested

"What a joke, who wouldn't want to brush!"

"I guess, the old woman misses her boyfriend more."

"Hey, Professor Ye is really too busy 0."

"Yeah, I'm away on business for more than a month, I miss..."

"It's enough of you. No one's real girlfriend is as sentimental as you are."

"Hahahaha, I laughed so hard."

"…………"

The message on the barrage, of course, can be seen by Dai Xiaomei.

She said helplessly to the water friends: "You guys, can't you be more reliable?"

Paused.

Sighing, Dai Xiaomei said: "I also really want to see our family Professor Ye, but I can't help it. He has his own job, so I can't disturb him."

talking,

There was a disappointed expression on her face.

The water friends in the live broadcast room naturally understood her thoughts, and everyone started to comfort the little girl on the barrage.

There are several noble water friends who even bought gifts.

In fact.

Everyone understands.

Just like them, Dai Xiaomei also hopes to see Ye Tian soon.

It's just that he has some things, not what they want to do.

"Okay, everyone, don't comfort me."

The mood of Dai Xiaomei quickly eased, and she said to everyone with a smile: "I believe that our Professor Ye will come back soon."

Just then.

Her phone rang suddenly.

Seeing the caller ID above, Dai Xiaomei was startled.

"Well, wait a minute, I'll answer the phone."

The little girl who stayed 3.3 stood up and walked outside the door while she was talking.

Come out the door.

She hit the connect button.

"husband?"

Holding the phone, Dai Xiaomei asked in surprise.

"Ah."

Ye Tian smiled and said: "Why, I didn't expect me to call you?"

"No, aren't you on a business trip?"

The little girl said in surprise.

She really didn't expect that Ye Tian would call herself.

Originally, according to her thinking, since she was on a business trip, she must not be able to communicate with the outside world.

"Come out to do something, and make a phone call if you have a chance."

Ye Tian said casually: "I remember your birthday is coming soon..."

???

???

Dai Xiaomei was stunned for a moment, she didn't expect Ye Tian to remember this matter.

PS: Ask for automatic subscription, ask for flowers, ask for evaluation tickets, ask for rewards! .

Chapter 265 The Birthday Gift of the Little Sister

For girls, birthday is a very important event.

Especially women in love, if their boyfriend forgets their birthday, they will be very sad.

At the least, they cry and make noises, and at worst, they break up.

of course.

None of this existed in Dai Xiaomei.

It's not that she doesn't want Ye Tian to care about her birthday.

It's because she knows.

My boyfriend is different from those ordinary people.

The things Ye Tian is busy with are all important matters related to the country.

Don't say that you are being unreasonable.

If he expressed dissatisfaction in the live broadcast room because Ye Tian didn't accompany him on his birthday, those water friends in the live broadcast room would spray himself to the point where he couldn't take care of himself.

This is a fact.

Dai Xiaomei knew it all by herself.

Who let Ye Tian's identity be there?

But she really didn't expect it.

Ye Tian actually still remembered this matter.

"Forget about the gift, I'm very happy if you can make a phone call!"

The little girl said with a smile.

She is really happy.

There is nothing happier than being remembered.

"Well."

Ye Tian thought for a while: "I'll make it up for you when I get home."

He also can't do 01 method.

If you go out to do errands by yourself, you can't go home to visit relatives alone.

There are so many people in the lab who are busy, if you, as a designer, take a vacation instead, it will definitely have a bad influence.

"it is good."

Hearing Ye Tian's words, Dai Xiaomei laughed in satisfaction.

put down the phone,

Her whole body seemed to be full of joy as if she had eaten honey.

Even when walking, I feel much lighter.

Going back to the live broadcast room, sitting in front of the computer, the little girl who stayed was smiling happily.

"There must be something good about the old woman."

The water friends have watched her live broadcast for so long, so they are naturally familiar with the habits of the little girl.

This woman is actually very good at hiding her thoughts.

Happy is happy.

Not happy is not happy.

As it is now, she is obviously happy.

"Thank you for your comfort."

Dai Xiaomei smiled and said: "Let's live broadcast well."

???

???

The water friends in the live broadcast room were dumbfounded.

Obviously you were the one who was unhappy just now, but all of us are clearly trying to comfort you, okay?

But everyone also understood that this woman must be happy.

As for the reason?

No need to guess, it must have something to do with that Professor Ye.

Otherwise, with the character of the dull girl, how could she go outside to answer the phone.

This is the inevitable result.

"Come on, let's play a game first."

With the words of Dai Xiaomei, the live broadcast room became lively again.

..............................

After comforting his girlfriend, Ye Tian naturally had to devote himself to the intense work.

Although the design drawings have been certified by experts in all aspects.

But everyone still decided to be more cautious before officially putting it into production.

no way.

AWACS is really important.

There is a reason for this.

To know,

Electromagnetic waves in the common band of radar propagate along a straight line.

No matter how flat the ground is, it is still a part of the earth, and the curvature must be reflected after all.

therefore,

Due to the influence of curvature, ground radar always has a blind spot, and the farther the radar is, the bigger the blind spot is.

This is why low-altitude and ultra-low-altitude flying has always been the main means of penetration: if you fly low, you will not be able to see it!

In the later period of World War II, some experienced kamikaze pilots in Japan took advantage of this point to break through the radar network of the Yingchan Navy and hit warships, causing serious casualties to Yingchan.

The idea to solve this problem is to push the boundary of ultra-low-altitude defense farther, that is, to put radar on the plane.

According to this idea, Yingjiang quickly developed a carrier-based early warning aircraft.

Although the radar can be seen far away when installed on the aircraft, the biggest problem is that the clutter is also coming.

The technical level of the 60s cannot filter clutter in real time, especially land clutter, which is much stronger than sea clutter.

The solution to the clutter problem is the pulse Doppler technology, which precisely measures the Doppler frequency shift of the target signal, and then removes the ground clutter.

Easier said than done, especially in land mountainous areas and urban clutter are still difficult problems in signal processing.

But at any rate, technological progress can handle signals on the sea surface and flat ground, which is already Amitabha.

After holding back for more than 20 years, the Eagle Sauce Air Force finally deployed the AN/APY-3 pulse Doppler radar on the E-1 early warning aircraft for the first time, and was able to freely overlook all living beings over the European Great Plains for the first time.

The superior performance of the E-3 has made the air forces of major countries salivate, and they all want to have their own early warning aircraft.

But pulse Doppler radar is not something you can play casually. Ground clutter signal processing, ultra-low sidelobe antenna, false alarm detection, etc. are easier said than done.

Eagle sauce has also been researched since the 50s, and it took more than 20 years of hardships to get it done.

Many countries in the world have made great efforts, some have achieved success, and some have not.
