A million profits

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

Then Wang Xuexin gave the drawings of the M16 rifle to Sun Erwei, and the bullet data would be given after all surveying and mapping radars were submitted.

But this is just in case, the transaction with Yingjiang will basically not go wrong. After all, Wang Xuexin and Yingjiang are not making a transaction... If Yingjiang deceived Wang Xuexin this time, he will do it again next time

The transaction is not that easy or requires a higher price. Yingjiang is a shrewd businessman, and it is impossible for them to do such a stupid thing.

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

The test results satisfy Wang Xuexin. It is quite accurate in surveying and mapping the highlands around Liyuan Airport. As Sun Erwei said, its error is within the range of 150 meters. If low-altitude surveying and mapping is done, the error will be further reduced. This was during World War II.

It's already quite remarkable.

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

At this time, the Japs' radar was still stuck on the analog signal, that is, what was seen on the Japs' radar was a signal similar to the beating of an electrocardiogram. It could only simply see from which direction an enemy plane was approaching, but it had no way of knowing the distance of the enemy planes.

How far away are you, let alone the location of the enemy aircraft... This is one of the reasons why the Eighth Route Army Air Force was able to successfully seize air supremacy.

Just imagine, if the Japanese radar is advanced enough to detect the position of the Eighth Route Army Air Force, it means that they are prepared for every battle and can even set traps for the Eighth Route Army Air Force.

If this were the case, the air battle between the Eighth Route Army and the Japanese would be much more difficult.

The radars introduced by the Eighth Route Army from Mao Xiong were similar. If there is any difference, Mao Xiong's radar can calculate the time when it receives the reflected signal, so it can manually calculate the distance of the target based on this time... However, this error is very large.

, because the basis of the data, which is the "time of the reflected signal", has errors.

Yingjiang's radar is different. Their radar has completed the transformation from analog signals to digital signals, so it can more accurately provide the coordinates, height and other information of the target.

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

Fortunately for Wang Xuexin... Yingjiang didn't know the use of this digital map at this time. They just used it as a kind of reconnaissance and early warning, or to improve the accuracy of bombing bombs.

What a fucking waste of natural resources!

This digital map can not only provide data for artillery detection radars, but will also become the data basis for missiles in the future... For example, a missile needs to approach the target at low altitude, so how does it know if there is a mountain blocking the way ahead and what kind of adjustments need to be made?

How can I pass through the narrow valley between the two mountains?

Of course what is needed is a digital map!

Wait a minute!

Wang Xuexin then 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 Mao Xiong?

Thinking of this, Wang Xuexin suddenly understood why the system charged him 200 million military coins.

Now that I think about it, it is really worth the price, because the artillery detection radar alone can easily repay the cost... No, for something like the artillery detection radar that can determine the outcome of the artillery on the battlefield, it has to be added later.

How about selling it back for zero?

And it doesn’t even sell Eagle Sauce. Countries around the world, including the Sun Never Sets, Gaul, etc., you have to buy it if you don’t want your artillery to be completely suppressed!

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

At that time, under the threat of such life and death worries...won't the great powers still line up and wait there one by one?

Wang Xuexin couldn't help but be overjoyed when he thought of this: Damn it, now it's paid! Why are you still working so hard to earn military industry coins? You can't eat them all in business!

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

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

Su Xin felt that it was right. The most difficult one was the calculation problem and the other was the digital map problem. These were not even accessible to Chinese military personnel and even to experts like Su Liguo.

But Wang Xuexin said "it has been solved". Can it really be solved?

As for other issues, such as wavelength... The mid-wave accuracy of the first-generation gun detection radar is not a big problem. It is not difficult to increase the rotation speed. So what else needs to be solved?

Just move the Mark 3 radar out and that’s almost it!

But Su Xin thought about it carefully and replied: "Mr. Su, the commander's intention is probably to make this radar more suitable for land warfare!"

Su Liguo said "Oh" and nodded.

The Mark 3 radar Eagle was developed for naval warfare...At this time, Eagle's main demand is naval warfare. In the Pacific battlefield, it competes with the Japanese fleet for sea control. There is not much demand for radars on land, so naval warfare radars are always at the forefront.

The first to be equipped is also the first.

In naval battles, it is also used to calibrate the ballistics of warships' main guns.

You must know that the range of the warship's main gun is often more than ten kilometers, which makes the Mark 3 radar very large and overweight... Warships can have a larger load, so Yingjiang does not care about the weight index, they even provide Mark 3

The radar is equipped with a layer of armor to protect it from shrapnel and bullet damage.

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

But if it is a land-based artillery detection radar, it does not need these protections and does not need such a long detection range... Probably only a detection range of 10 kilometers is enough.

The reason is that the artillery detection radar is used to detect enemy artillery shells, and it requires the artillery shells to reach a certain height to detect them.

For example, the enemy's longest-range field gun is the Type 90 75MM field gun, which has a range of 15 kilometers.

There is basically no need to detect the shell before it reaches its highest point, because it will probably be blocked by buildings or mountains and cannot be detected.

After halving, it is 7 kilometers. If the detection distance of the artillery detection radar is 10 kilometers, then there is still 3 kilometers of deployment space.

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

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