Chapter 804 Gao Zhendong’s New Suggestion

Even though the reminders have been made so obvious, the comrades are still very smart.

"Amplitude!" This is the easiest thing to think of, as they often touch the radio.

"The amplitude won't work. The signal amplitude is greatly affected by reflectivity, distance, rain and fog. It cannot be directly distinguished by simple signal amplitude. If it is modulated like a radio, the system complexity will increase greatly." Before Gao Zhendong could answer, a comrade had already shot down this idea.

"Then it's the frequency!" Anyway, there are only a few basic parameters of the signal. If you guess them one by one, you will always be able to guess it.

Hearing this, Gao Zhendong nodded: "Yes, the frequency is OK, and there are many ways to adjust the frequency."

"Many kinds?"

"Yes, there are many kinds, suitable for different occasions, each with its own advantages and disadvantages."

Gao Zhendong introduced frequency-related arithmetic codes, precise frequency codes, variable interval codes, pseudo-random codes and other methods. The comrades were fascinated by what they heard. It turned out that there were so many coding methods that could be used, and these coding methods had so many differences and uses.

After introducing various coding methods, Gao Zhendong pulled things back to the topic. After all, these details are not needed for the time being. The most convenient way now is to use pulse width modulation to solve the problem. However, he still has a lot of suggestions on the overall laser-guided bomb.

"In fact, from a practical perspective, I suggest that you ask the Air Force to produce a batch of them for training and trials, even if the problem of simultaneous attack on multiple targets has not been solved. In fact, for precision-guided weapons such as laser-guided bombs, there are not many scenarios where multiple targets can be attacked simultaneously. Most of the time, it is still about attacking specific targets. In this case, a large enough bomb can often solve the problem. If that doesn't work, you can throw several at a time and use one to illuminate the target."

Mr. Zhang nodded repeatedly: "We have thought about this before, but the Air Force was quite adamant. Now with your suggestion, I think they will consider it carefully."

The same words, spoken by different people, have different effects.

Gao Zhendong also didn't think that Chunlei Factory was using its own reputation as a banner. Objectively speaking, the Air Equipment Bureau's trust in them was not as high as that in itself. This was a fact.

The biggest reason why he proposed that no matter how well the problem of multi-target attack was solved, a batch of laser-guided bombs should be produced for trial use was time.

If nothing unexpected happens, the time for Zang San to commit suicide should not be far away. Based on what Gao Zhendong knew about the nature of his enemies in his previous life, this matter will change only with time, but the event itself will not change.

Before this point in time, the more things we have in our hands, the more attempts we can make. When the quantity of certain things reaches a certain level, it may be possible for qualitative changes to occur.

"How is your infantry portable illuminator?" This is another thing that Gao Zhendong is concerned about. For aircraft, the guidance pod method is undoubtedly more flexible and convenient than developing a specific illumination indication system for each aircraft model. In some cases, if scouts can have a portable illuminator, it can further enhance the flexibility of using this weapon.

Speaking of this, Mr. Zhang felt a little troubled.

"It is a bit difficult. It is difficult to achieve the irradiation power on the aircraft while making it convenient for infantry to carry it. We are currently carrying out modular design of the irradiator, and strive to make it so that four infantrymen can carry it more easily after disassembling it." After all, no matter how limited the aircraft's load capacity is, it is still much heavier than that of infantry. 4 to 200 kilograms is not unacceptable for an aircraft, but it is too heavy for infantry.

Gao Zhendong looked at him in confusion: "Why do we need to achieve the same irradiation power as the aircraft pod?"

"For the sake of range. If the power cannot be reached, the guidance distance will be difficult to meet the required range." Mr. Zhang also looked puzzled. The illumination power is a hard indicator and it is impossible to reduce it.

"But infantrymen usually illuminate the target from close range, and the distance from the illumination point to the target is less affected by rain and fog. It can be said that the complete optical path length of the illumination is only about 60% of the aircraft's own illumination path at most. There is no need to use such a large power."

Gao Zhendong drew a light path diagram on the blackboard, which immediately made Mr. Zhang become autistic.

"This... yes, I'm so stupid." Mr. Zhang slapped his head. He couldn't figure out why he didn't consider this situation.

"Moreover, you can learn from the technology of long-range dispensers and install simple inertial guidance on the bombs. Even your aircraft does not need to receive the illumination signal. You can just drop the bomb according to the coordinates given by the infantry. After the bomb flies over, you can intercept the illumination signal of the infantry's low-power illuminator and follow this signal to fire." Gao Zhendong gave a simple composite guidance idea. It is more troublesome, but it is not impossible to achieve. Is it possible to do this? Mr. Zhang felt that he had opened his eyes. This method was unheard of and he could not think of it no matter how hard he tried.

But following Gao Zhendong's line of thought, it seems that it is theoretically feasible. Maybe the reliability is not that high, but in any case, this method of achieving precision strikes is always more reliable than horizontal bombing.

For the Air Force, a hit rate of more than 85% is actually not that important. As long as one out of 10 bombs can hit the target in this way, it is pure profit.

Take the famous laser-guided bomb, the Thanh Hoa Bridge in Jiaozhi, for example. The American guys bombed the bridge for seven years, from 7 to 1965, but they just couldn't do anything about it. The desperate American guys even thought of such tricks as releasing drifting discus bombs from upstream, but they still had no patience for the bridge.

In the end, it was the newly developed laser-guided bomb that destroyed the bridge in one fell swoop. This shows the combat effectiveness of precision-guided weapons.

So Gao Zhendong's idea is very simple, which is to try to broaden the application scenarios of laser-guided bombs and increase the ways of attack. Even if it is not very reliable, it might as well be tried. Maybe it will work.

It is always better to have a solution than to be helpless, even if the solution is not very reliable and requires a little bit of luck. However, as the old saying goes, opportunities always favor those who are prepared. What Gao Zhendong did was to make more preparations for this kind of weapon, at least to have a chance of luck.

Thinking of this, Gao Zhendong made another suggestion to Mr. Zhang.

"I suggest that you integrate the thermal imager into the sighting system of the portable illuminator while reducing the power of the infantry illuminator. If you cannot integrate it directly, at least provide a convenient interface for the thermal imager. If the conditions for the airborne pod are ripe, you can also integrate the thermal imager. Don't worry about the resolution. If necessary, you can improve the resolution of the thermal imager at a considerable cost."

For scouts, as long as they can see the enemy, they can use the illuminator to provide illumination for laser-guided weapons. Therefore, it is very important for this illuminator or the matching sighting and observation device to have night vision capability. For a considerable number of enemies who use anti-aircraft guns as their main air defense weapon, night bombing is simply unsolvable for them.

For night bombing, first of all, one must be able to see clearly. Night bombing was not very popular during S2, mainly because the bombers themselves could not see.

However, this situation changed when the American LeMay was doing barbecue. LeMay often carried out night bombings, but his target indication was rather special - he would use incendiary bombs to make a "cross" in the Japanese city, and other bombers would just throw incendiary bombs around the cross and that would be the end of the matter.

In any case, there are not many situations that can match Li Mei's conditions. If you want to carry out night bombing well, the most important thing is to be able to see it yourself.

"Chief Engineer Gao, if you can provide a high-resolution thermal imager, I am confident that I can make the pod better." Gao Zhendong's series of suggestions boosted General Manager Zhang's morale. It's just a matter of piling up materials, just piling up!
Having said that, he was still amazed at the broad-mindedness of Gao Zhendong's thinking. Chief Engineer Gao's thoughts were indeed more far-reaching and comprehensive than his own.

Gao Zhendong stayed at the Chunlei Factory for three days. During these three days, he mainly worked with his comrades at the Chunlei Factory to implement improvements to laser-guided bombs.

One is the laser pulse width coding technology. Although he gave the idea, the comrades at Chunlei Factory, who were not very familiar with digital circuits, still needed some help to implement this technology.

Then there is the matter of the pod and the infantry portable illuminator. Together with General Zhang, he re-determined the power indicators of the infantry portable illuminator to ensure that the infantry portable illuminator can be fully manufactured as soon as possible. Gao Zhendong's idea is to fully implement this matter before October.

Combat requires time to prepare. Judging from the natural conditions, our transportation capabilities, and the enemy's inertia of action, it is highly likely that the timing of this event will not change much.

Judging from the current progress of the infantry portable illuminator, it should not be a problem to catch up with this node. Mr. Zhang and his team have already accumulated a considerable amount of experience before this. With the irradiation power almost cut in half, it should be feasible to make something usable.

The only thing Gao Zhendong repeatedly emphasized on this matter was that the high-altitude and cold weather conditions must be fully considered and the high-altitude and cold weather tests must be carried out in a solid manner.

As for the laser-guided pod with integrated thermal imager, it was only included in the plan and the scheme was determined, but Gao Zhendong did not consider completing it before the deadline. As long as the infantry portable pod integrates the existing small thermal imager and laser-guided bombs to increase inertial navigation, it can basically achieve a certain degree of night combat precision bombing.

The night before leaving Chunlei Factory, Gao Zhendong thought about it, took out a pen and paper, and wrote a title on the cover paper.

——"Research and suggestions on the use of various new weapons in high-altitude and cold conditions."
