Bright Sword Military System

Chapter 1441 Transferred to Taiyuan
The new positioning method mentioned by Wang Xuexin is actually a passive radar developed in modern times.

The reason why Wang Xuexin did not directly mention passive radar is because the development of this radar is not so fast, and the other is because it is difficult to achieve precise positioning, even in modern times.

The principle of passive radar is actually very simple: if the enemy has a radar that continuously emits electromagnetic waves to detect targets, then in principle, we only need to use two passive radars to receive electromagnetic waves to get the direction of the source of emission, and then combine the numbers according to the direction Draw two straight lines on the map, and the intersection of the two straight lines is the position of the emission source.

This is the case in theory, but in practice, this "direction" is a range and cannot be accurate to a straight line, because no matter how sensitive and accurate the passive radar is, it cannot determine a straight line to the source of emission based on the electromagnetic wave, it can only determine that the electromagnetic wave is from a certain error emitted within the range.

Therefore, what can be obtained is the intersection of two "ranges", and finally a region is obtained.

And because of the principle of "a thousand miles of difference" in terms of angles... It's like shooting. Although the muzzle of the gun is only a little bit off, the error will be large because the target is far away.

Therefore, the area detected and calculated by passive radar is also very large, and it is even too large to be covered by artillery fire.

Therefore, if you want to accurately destroy the enemy's artillery detection radar, you have to rely on "opening the back door".

As for why Su Xin was asked to develop passive radar... Wang Xuexin is preparing for future anti-radiation missiles.

Wang Xuexin will not participate in the report. Su Xin will make a detailed report to the headquarters based on the results of the discussion.

At that time, the chief and the chief of staff were still having a headache over whether to use the gun detection radar to trade. After receiving the report, they couldn't help but slapped the table and applauded.

"Now all the problems will be solved!" The chief laughed loudly: "The problem of public opinion, the oil problem, and the problem that the artillery detection radar will be turned against us by the enemy, all of them don't exist! This Wang Xuexin, there is Two brushes!"

"Yes!" The chief of staff sighed holding the meeting report: "It should be said that not only do these problems no longer exist, but they may also dig two big holes for the recalcitrant army and the devils: once the gun detection radar is sold, the recalcitrant army and the devils will be able to communicate with each other." Just fight, if you want to fight our Eighth Route Army... Not only will our army find you as soon as you meet, but it will also let our army know the location of their artillery at the first time! You can kill multiple birds with one stroke! Comrade Wang Xuexin will think of it This is the solution!"

Then the chief of staff suggested: "Chief, look... How about letting Comrade Wang Xuexin manage Taiyuan?"

The chief thought for a while, then nodded and said: "Good idea! Taiyuan is different from other cities. It has airports, military factories, coal mines, steel factories, textile factories and other factories. This is not as simple as a city, but It is the concentration place for our army to develop industry and military equipment, and it is also the cradle for scientific research and development of military talents, no one is more suitable than Comrade Wang Xuexin!"

It can be seen from this that the chief has a deep understanding of the industrial status of the Eighth Route Army: at this time, the industrial layout of the Eighth Route Army is actually unreasonable. For example, the scientific research personnel and the rifle production line are in three stores, the "La 5" production line is in Laheba, and the automobile production base In Ningbei Township again...

These industries are scattered in the east, west, north and south of the base area, and Wang Xuexin is in Liyuan, so even if he wants to hold a meeting with the scientific research team, he has to take Yingjiang's plane to fly there.

In the past, there was no way to do this. The traffic in the base area was backward and there was no suitable place to form an industrial settlement. At the same time, I was worried that the industry would be bombed by devils if the industry was too concentrated.

Taking Taiyuan will be different. To transfer Wang Xuexin and the research team to Taiyuan, you only need to go out for a meeting, and at most it will take a ten-minute car ride.

However, the chief did not give an order immediately, he waited for six or seven days.

In the past few days, the Eighth Route Army has captured Pingxing Pass, Niangzi Pass, and Tianjing Pass... Most of these passes were raids launched at night.

The choice to launch raids at night is not because the Eighth Route Army is good at night battles, but because the Eighth Route Army has artillery detection radar... The artillery detection radar does not affect its use at night, but it is difficult for the devil's artillery observers to spot targets at night, especially infantry.

As a result, the devil's artillery was always inaccurate, and would be blown up by the artillery of the Eighth Route Army as soon as it fired.

Next, only Zijing Pass and Huang Yu Pass are left facing the devils.

But the devils didn't intend to defend these two passes at all... The devils seemed to realize one thing: with the Eighth Route Army's artillery detection radar, it was impossible to defend such a narrow pass where the troops could not be deployed.

The ancients had a saying: "When you meet on a narrow road, the brave wins."

The pass is a narrow road, and the Eighth Route Army is braver than the devils, and more importantly, the "bravery" of the Eighth Route Army is reflected in the artillery detection radar... With its help, it can not only suppress the devils' artillery, but also clean up the devils' blockhouses and gun towers along the way.

Seeing that this battle was impossible to fight, the devils had no meaning except to increase casualties, so they planted a large number of mines at the remaining two passes and voluntarily withdrew after blasting the fortifications.

At this point, the entire territory of Shanxi was declared recovered.

This is of great significance to the Eighth Route Army, because as I said before, Shanxi is a "closed but not closed castle".

However, "unable to attack" seems to be inaccurate. Okamura Ningji thought that the Eighth Route Army's "unable to attack" capsized...

Of course, the devils don't have helicopters, so the Eighth Route Army doesn't need to worry about this.

This day, Wang Xuexin was sending a telegram to Chu Yunfei.

Although the matter had been settled a long time ago, Wang Xuexin was worried that the reply would make Chu Yunfei suspicious: "How could the Eighth Route Army make a decision so quickly on such a big matter? Shouldn't they have a meeting to discuss and then struggle for a few days?"

Therefore, Wang Xuexin deliberately waited for a few days, and then sent a telegram to Chu Yunfei in a very helpless tone: "Brother Chu, with my mediation, the chief finally agreed to the deal, please contact Chongqing as soon as possible." !"

When Chu Yunfei saw the telegram, he was so happy that he "haha" laughed: "Everyone says that you, Little Northeast, have great powers, so don't you have to give in today?"

As soon as he said that, he sent a telegram to Chongqing asking them to send someone to negotiate with the Eighth Route Army to discuss the transaction.

At this time, Wang Xuexin received a telegram from the headquarters: "Ling, the aviation regiment and headquarters moved to Taiyuan Wusu Airport! Comrade Wang Xuexin is fully responsible for the defense of Taiyuan!"

Wang Xuexin couldn't help being taken aback, this is a shotgun change, and he moved back to the city from a remote Liyuan.

but……

Wang Xuexin looked at the mountains outside the window, and was really reluctant to stay here for a long time.
