Bright Sword Military System

Chapter 1321

The transaction between Wang Xuexin and Yingjiang went very smoothly, and two B17s equipped with ground mapping radars landed at Liyuan Airport three days later.

Then Wang Xuexin handed over the drawings of the M16 rifle to Sun Erwei, and the data of the bullets will be given after all the surveying and mapping radars are handed over.

But this is just in case, the deal with Ying Jiang will basically not go wrong. After all, Wang Xuexin and Ying Jiang are not making a deal... If Ying Jiang cheated Wang Xuexin this time, I will do it next time Trading is not so easy or requires a higher price. Eagle sauce is a shrewd businessman, and it is impossible for them to do such a stupid thing.

After getting the ground surveying and mapping radar, Wang Xuexin immediately conducted a test on it, that is, let it fly around in the air and record the ground data.

Wang Xuexin is very satisfied with the test results. Its surveying and mapping of the highlands around Liyuan Airport is quite accurate. As Sun Erwei said, the error is within 150 meters. If the low-altitude surveying and mapping, the error will be further reduced. Already quite remarkable.

From this ground surveying and mapping radar, Wang Xuexin can also see the technological gap between Devil and Yingjiang.

At this time, the Devil's radar is still on the analog signal, that is, what the Devil's radar sees is still a signal similar to the beating of an electrocardiogram. It can only simply see whether there is an enemy aircraft approaching in which direction, but it has no way of knowing the distance of the enemy aircraft. No matter how far away you are, let alone the position of the enemy plane... This is one of the reasons why the Eighth Route Army Air Force was able to successfully seize air supremacy.

Just imagine, if the devil's radar is advanced enough to detect the Air Force of the Eighth Route Army, it means that he is prepared for every battle and even can set traps against the Air Force of the Eighth Route Army.

If this is the case, the air battle between the Eighth Route Army and the devils will be much more difficult.

The radar imported by the Eighth Route Army from Mao Xiong is similar. If there is any difference, Mao Xiong’s radar can calculate the time of receiving the reflected signal, so it can manually calculate the distance of the target according to this time... But this error is very large , because the basis of the data, that is, the "time of reflected signal" has errors.

Yingjiang's radar is different. Their radar has completed the transformation from analog signal to digital signal, so it can give more accurate information such as the coordinates and height of the target.

Just like the current ground surveying and mapping radar, as long as it flies around in the air, it can immediately get a digital map of the nearby area.

Fortunately for Wang Xuexin...Yingjiang still doesn't know what the digital map is useful for at this time. They just use it as a kind of reconnaissance and early warning, or to improve the accuracy of bombing for bombers.

What a fucking waste of money!

This digital map can not only provide data for gun detection radar, but also become the data basis for missiles in the future... For example, if a missile needs to approach the target at a low altitude, how can it know if there is a mountain blocking the way ahead? How will it know what adjustments need to be made? To pass through the narrow valley between two mountains?
Of course, what is needed is a digital map!
Wait a minute!
Wang Xuexin quickly thought, since even Yingjiang doesn't know how to use it, does that mean... After Wang Xuexin develops the artillery detection radar in the future, he can sell it to Yingjiang or Maoxiong?
Thinking of this, Wang Xuexin suddenly understood why the system charged him [-] million military coins.

Now that I think about it, it’s really worth the price, because the artillery detection radar alone can easily pay back the cost... No, for the artillery detection radar, which can determine the outcome of the artillery on the battlefield, it has to be added later. Sell ​​it back for zero?

And it doesn't sell the Eagle Sauce family. Countries around the world, including the sun never sets, Gaul, etc., if you don't want your artillery to be completely suppressed, you have to buy it!

We have to package the technology to prevent other countries from imitating it.

At that time, under the threat of this kind of life and death...wouldn't the great powers have to wait in line one by one?
Thinking of this, Wang Xuexin couldn't help but be overjoyed: Damn it, it's here!What kind of military coins are you working so hard to earn? You can’t finish your business!

Wang Xuexin did not hesitate, he immediately sent a telegram to Su Liguo: "The problem of the digital map has been solved, and the research and development of the gun detection radar will begin immediately!"

Su Liguo on the other side was only surprised. He said to Su Xin: "The two most difficult parts... the team leader said that they can be solved, but these two problems have been solved, so what else is there to develop?"

Su Xin felt right, the most difficult one was the calculation problem and the other was the digital map problem. These were not even a threshold for Chinese military personnel and even for Su Liguo, an expert.

But Wang Xuexin said "it has been solved", can it really be solved?
As for other issues, such as wavelength... the accuracy of the first-generation artillery radar with medium-wave accuracy is not a big problem, and it is not difficult to increase the rotation speed, so what else needs to be solved?
Just move the Mark 3 radar out and it's almost the same!
However, Su Xin thought about it in detail, and replied: "Old Su, what the commander means is probably to make this radar more suitable for land warfare!"

Su Liguo nodded with an "oh".

The Mark 3 radar was developed by Eagle Sauce to be used in naval warfare... At this time, Eagle Sauce’s main requirement is naval warfare. In the Pacific battlefield, it competes with the devil fleet for sea control. There is not much demand for radar on land, so naval warfare radar is always in the lead. The first is also the first to equip.

In naval battles, it is also used to correct the ballistics of warship main guns.

You must know that the range of the warship's main gun is more than ten kilometers, which makes the Mark 3 radar very large and heavy... Warships can have a large load, so Yingjiang doesn't care about the weight index, and they are even for the Mark 3. The radar is equipped with a layer of armor to make it resistant to damage from shrapnel and bullets.

(Note: The range of the main gun of the Eagle Sauce Fletcher-class destroyer is 16 kilometers)

But if it is a gun detection radar for land use, it does not need these protections and does not need such a long detection distance... probably only 10 kilometers of detection distance is enough.

The reason is that the gun detection radar is used to detect enemy shells, and it needs the shells to reach a certain height to be detected.

For example, the wild artillery with the longest range of the enemy devils is the 90-type 75MM field artillery, and its range is 15 kilometers.

There is little need to detect it until its shell reaches its highest point, as it is likely to be blocked by buildings or mountains.

After half a minute, it is 7 kilometers. If the detection range of the gun detection radar is 10 kilometers, there is still 3 kilometers of deployment space.

Thinking of this, Su Liguo knew what he was going to do.

He wants to miniaturize and lighten the Mark 3 radar. It would be ideal if it could be mounted on a truck!
