The icy bullet naturally wouldn't pay attention to Carter, who looked worried at the moment.

As soon as the warheads of the twenty-four V-2FJDD anti-ship ballistic missiles were opened, five inflating balloons floated out of each warhead.

The warhead needs to conduct high-altitude guidance before returning to the atmosphere, search for the target and determine the relative distance, and adjust the ballistic trajectory when it returns to the atmosphere for high-altitude gliding. Guidance requires a warhead to detect the target, so it cannot be completely shielded, and the antenna window must be left.

Therefore, the warhead cannot be invisible, and the decoy bomb has become the best target to confuse the opponent.

But in order to prevent the decoy balloon from interfering with itself and to enable it to have all the signals similar to the warhead, it is not a very simple matter.

The country that has developed decoy warheads in the world is Russia's most complete.

Even in the United States, the research results in this area are far from ideal.

The missiles and decoys of the Red Police Corps are quite clever.

When these released balloons are inflated, the temperature inside the balloons is also increasing unevenly.

The technology for detecting missile warheads is not just radar, but also the infrared system of remote sensing satellites. Because of the need for deception radar, deception infrared system is also the most important thing.

The surface of the anti-ship ballistic missile decoy balloon is coated with a metal film and covered with the same radar absorbing paint. The counterweight is installed to produce different nutation angles and precession periods, and the process of controlling the mother capsule to release the balloon forms different rolling periods. To cool the balloon, install an electric heating film inside the balloon, set different heating temperatures for the electric heating films at different positions, and keep the heating temperature difference between the balloons.

Such a balloon is a differentiated decoy, and the warhead also has the nature of anti-simulation decoy. In order to have enough space and carry weight, the weight of the missile warhead is strictly controlled, and the thrust is relatively stronger than that of ordinary ballistic missiles. Make it have a surplus load of up to 100 kilograms, so that it has enough weight to install radar jammers and other equipment after carrying the balloon.

Therefore, the cost of Cai Ruichen's production of anti-ship ballistic missiles is actually comparable to those of conventional ballistic missiles with a range of five or six thousand kilometers.

The warhead of the missile is also specially designed. The heat shield is a cooling barrier made of a metal shell. A cavity is formed between the inner and outer walls. Liquid nitrogen is introduced to cover the entire warhead so that the outer surface of the warhead Cool to the point where the infrared seeker is hard to find.

Cooling the warhead is the most critical point for breaking through the anti-missile system. Terminal anti-missiles are all missiles that rely on radar and infrared to lock incoming missiles.

For the US Sea-based Standard-3 missile, if the interceptor can find ordinary warheads 300 kilometers away, the discovery distance of the warhead after cooling is less than three kilometers, which is visible for the standard-3 interceptor. It is impossible to find out.

In order to prevent the warhead from reflecting the earth's glow to the interceptor and exposing the target, the V-2FJDD infrared stealth guided missile is deployed in a stable spin around the axis of symmetry when the missile is released, and is oriented in a certain orientation when it reenters the atmosphere. Its axis of symmetry is in line with its velocity vector.

However, the U.S. military still has the ability to identify true and false warheads, that is, to use a sound early warning system to make distinctions.

The US sea-based mid-range interception system mainly relies on X-band tracking radars and phased array radars to identify targets and guide missiles to send interceptors into the interceptor orbit. Its main recognition methods include: feature recognition, which estimates the target's flight attitude, structural characteristics, material characteristics, etc. through the amplitude, phase, polarization frequency characteristics and changes of the radar echo signal.

At this moment, when the anti-ship ballistic missile warhead releases fake warheads, the US military is also making final efforts for this.

"Acquire the structural feature information of the target through high-resolution radar imaging,...take the target determined by the above different measures as the threat target, compare the database, observe and comprehensively judge the target type..."

Infrared equipment measures the three parameters of the warhead and the decoy in the middle of the trajectory as the basis for optical identification in the middle of the trajectory, namely the surface temperature of the target and its rate of change, the target's radiation intensity and its rate of change, and the effective radiation area of ​​the target. The value is connected with the motion characteristics and radiation characteristics of the measured target, combined with a priori recognition judgment and algorithm, to identify true and false warheads.

Among them, temperature and radiation intensity change rate are the key parameters of the identification criterion, because they collectively reflect the physical and dynamic characteristics of the target. Especially when the ground cannot provide the target-interceptor relative position and the infrared optical system cannot measure the distance, it is the only identification standard.

However, the United States is destined to be disappointed. The anti-missile capabilities possessed by the United States, or the detection foundation established by all anti-missile systems in the world, seem to be a shield.

The missile at the base is a spear designed for this shield, in order to pierce this shield.

The US anti-missile system should not be underestimated. This is what Cai Ruichen has been admonishing to himself for a long time.

But he also wanted to try to see how perfect defense the US shield can support.

The missiles of the Red Police Corps have super-strong breakthrough capabilities, and the decoy design is aimed at most of the world's detection capabilities.

When the Red Police Corps attacked the Israeli mainland, the United States should have realized it.

After all, Israel also has a very advanced air defense and anti-missile system, but in the face of the Iraqi-Syrian federal missile strike, the sense of powerlessness is enough to cause the US military to arouse great vigilance.

Unfortunately, ~lightnovelpub.net~ The US military is indeed very careful, and even plans to deploy X-band radars in the Indian Ocean, but in the face of aggressive missiles, all this is too late.

This is the biggest difference between the Iraqi-Syrian Federation and the United States. In the Iraq-Syria federal government, whether it is military or political, Cai Ruichen belongs to the supreme position of Gan Gang's arbitrariness.

The United States is completely different. It often takes as long as one or two years for a policy change or military force mobilization.

Many things need to be passed, and the efficiency of the government will slow down when there are more people. This is the biggest difference between the two sides.

However, even if the US military can really deploy a complete anti-missile system in the Indian Ocean, it will be helpless in the face of advanced decoy bombs such as the Islamic Federation.

Because all simulated decoy balloons, whether it is radar reflection data or infrared data, are no different from real warheads. The aluminum alloy camouflage on the outside is exactly the same as real warheads.

With the current US anti-missile methods, it can be said that it is almost impossible to find real warheads. The only thing that can be done is to intercept all the multi-warheads. (To be continued.) Enable new URL
