Messerschmitt suddenly asked, "Mr. Karl, how is the development of the Vulcan cannon progressing now?" I think it caused quite a stir at the Stockholm International Defense Exhibition. ”

Karl sighed and said, "Alas, don't mention it. Without Philip, the progress of this Vulcan cannon is slow, and I don't know when it will succeed, and there are a lot of problems. ”

Philip squinted his eyes and smiled, "Do you two think that this weapon is easy to develop?" Actually, it's no simpler than a jet engine. In particular, the Vulcan cannon for ground air defense, it is not just a cannon so simple, it is also necessary to develop a gun-sighting radar, if it is only controlled manually, it is very difficult to deal with high-speed targets in the air, of course, the current low-speed fighter is relatively easy to hit. Like the jet fighters of the future, they are fast and rely entirely on the human eye and brain, which is simply not enough. ”

Karl said in surprise: "Artillery sight radar? What kind of weapon is this? I've never heard of it, Dr. Wiley, have you heard? ”

Messerschmidt shook his head lightly and said, "It's the first time I've heard of it. But radar, I heard that someone is doing it, and I really don't know what it does. Philip, you also have research on this? ”

Philip smiled and said: "I believe that radar will soon appear in the world and will be used in the military." Of course, radar is not just for the military, but can do a lot of things. Artillery sighting radar is the product of the combination of radar and artillery. I envision that in the future, air targets will become faster and faster, and it will be difficult to shoot down air targets by hand alone. If the radar and artillery are integrated into one platform, the radar can be used to detect and track the air target, and the direction and distance information of the target can be determined, and then the anti-aircraft gun can be controlled to aim and shoot through the commander, so that the shooting accuracy will be greatly improved, and a lot of shells will not be wasted. ”

The more Carl listened, the more shocked he became, this kind of gunsight radar is too powerful, if this kind of thing can be developed, then I don't know how much of a sensation it will cause! With the artillery sighting radar, the Vulcan cannon is like having a pair of sharp eyes, which is really like a tiger with wings.

Messerschmitt thought differently, and as he listened, he wondered what would happen if this radar and Vulcan were to be put on an airplane. I don't know how big and heavy this radar is, and there is also a Vulcan cannon, which is not small in size, and it seems that there are still some difficulties.

Karl's eyes widened and he asked expectantly, "Philip, should we start developing this radar?" You can't let other arms companies get ahead of you. How much money is needed, you just say it! ”

Philip spread his hands and said helplessly: "Mr. Karl, I only know a little bit of the principle. At present, it is very difficult to develop radar, because it is still very difficult to manufacture many electronic components and equipment for radar, and it is also very large in size. If we want to develop completely independently, we don't have the conditions yet. A radar is composed of an antenna, a transmitter, a receiver, a signal processor and a terminal device, and the power required for the pulsed electromagnetic wave generated by the radar transmitter is also very large, and the transmitter shoots the electromagnetic wave energy in a certain direction of space through the antenna, and the object in this direction reflects the electromagnetic wave encountered; The radar antenna receives this reflected wave and sends it to the receiving device for processing, extracting certain information about the object, such as the distance from the target object to the radar, the rate of change of range or radial velocity, bearing, altitude, etc. Of course, we can do some pre-research now, and we can develop it as soon as the conditions are ripe. ”

Karl said with some regret: "Philip, aren't you kidding us?" I thought it would be developed soon, so maybe it could make a big splash at the second Stockholm International Defense Exhibition, so that our ordnance industrial complex could be on fire. So what's so special about this kind of artillery sighting radar, you can first tell me about it, I'm in a hurry, if I don't find out, I'm afraid I won't be able to sleep at night. ”

Philip smiled bitterly and said, "Mr. Karl, don't be too anxious, I believe that the conditions for the development of radar will soon be ripe." Artillery targeting radar, it is better to use centimeter-band or longer radar waves, so that it has a short range of action, a narrow radar beam, and can search for targets according to the intelligence provided by the target designation radar, and if necessary, search for targets on their own. It uses a highly directional antenna to send a needle-like beam and receive a target echo signal. After discovering the target, switch to automatic tracking, so that the antenna axis is aimed at the target. When the target deviates from the direction of the antenna axis, an azimuth and high and low angle error signals are generated. The error signal acts on the antenna control device, causing the antenna shaft to quickly turn to the target. In the process of automatic tracking, the artillery aiming radar continuously measures the azimuth, high and low angles and distances of the target, and transmits these coordinate data to the commander, so as to control the aiming and firing of anti-aircraft guns. ”

Messerschmidt exclaimed: "Ah, it turns out that radar is such a complex weapon. I thought it was so simple and small that it could even be carried on an airplane and become a clairvoyant for fighter jets. When you say that, Philip, I suddenly feel that there is no hope. ”

Philip stretched out his index finger and shook it, "No! Dr. Wiley, your vision is completely realizable, but of course it will be a long time later, and it will only be possible to move radar to airplanes if radar technology advances and the radar continues to shrink in size and increase in accuracy. For example, we can attach a miniaturized radar to a bomber, so that it can search for large targets on the ground and at sea, and can provide navigation information, implement target aiming, and so on. Even on ordinary transport planes and passenger aircraft, radar can also be installed, and this radar becomes a navigation radar, which is used to observe the meteorological conditions, air targets and terrain features in front of the carrier aircraft, so as to ensure the accurate navigation and flight safety of the aircraft. ”

Messerschmitt nodded again and again: "Great! Philip, you've reminded me. I believe that radar will certainly make great achievements in aviation weapons in the future, and we should make good plans for the development and development of radar as soon as possible, and this should become an important development direction of our Dragon Soul Ordnance Industrial Complex. ”

Philip thought for a moment and said, "Dr. Willie is getting more and more discerning. Yes, I think we can develop the simplest ranging radar first, although it can only measure the distance between the target and the radar, of course, the relative velocity of the target can also be calculated from the ratio of distance to time, and the azimuth and altitude of the target cannot be measured, and the range of action is only a few kilometers. Through the development of this simplest ranging radar, we can accumulate experience in research and development, and temper a team of personnel for radar development, and then we can develop products such as gunsight radar and airborne radar. ”
