Quantum radar. It can be two-layer graphene. The system puts quantum entanglement between particles that are locked in those squares. The system should use particle pairs. In transmitting particle pairs. The outer particle is at a lower energy level. That particle transmits signals. And in receiving a particle pair, the outer particle is in the lower energy size, which allows it to transport information into the system. That kind of quantum dot-based technology can break the stealth material. In that system, the frame spins, and that makes it possible to create. The scanning Doppler radar.  

In some other versions, the system uses a cut nanotube. The nanotube forms the crown-shaped structure. And in the middle of the nanotube is the antenna that transmits. The nanotube spins around that antenna. And that allows it to create the nanotechnical Doppler radar. The main problem. With Doppler radars. The antenna must move. 

So. That it can work right. The reason for that is this. The same antenna cannot transmit. And receive at the same time. The moving antenna makes it possible. That. The angle of the receiving antenna changes. This makes it possible. To determine the location of the point where signals reflect. Normally, the radar has a light parabolic shape, which makes it possible to determine the distance to objects. Another version. It is easier to use the change of frequency when the object comes straight to the radar.

Those transmitter-receiver antenna pairs can have an adjustable angle. This allows them to measure distance to the target. Very accurately. In those cases, the other antennas can send plus, and the other transmitter antennas can send A minus mark. Radio signals. Those signals form an electric arc to the target. 

This is important when something comes. Straight ahead to radar. The quantum dot-based radar can also use moving structures. 

Sometimes it’s discussed. About the possibility of using things like helium atoms as quantum radars. The atom’s core acts as a transmitter. And electrons act as a receiver. The system can also use things like excitons. The hole acts as a receiver. And the electron. Which orbits the hole act as a transmitter. Those exciton-based systems are already in use. 

In the laser-based systems. They can use the one-pixel scanner. And the nano-lasers. Those one-pixel systems can be in a frame that spins around the laser. 

The new nanotechnical lasers can act as pairs with the pixels that can receive the reflection. The laser. It can have a frame. Those receiving pixels are in that frame. As a circle. This makes it possible to create optical lidar (”laser radar”) that can scan surfaces and operate over longer distances.

The 4G and 5G network co-operation with aerial vehicles

The 4G and 5G network co-operation with aerial vehicles

The ground-based data networks are not always suitable to cooperate with aerial vehicles. The problem with compatible is causing, because of the land-based data networks need different kind of roaming protocol than land-based communication equipment. The roaming means the ability to change the relay station automatically, and the system works that the network is locating the mobile device, and when the other support station turns to dominant, the station would be changed.

And the aerial vehicle has problems that the roaming must happen faster than with the ground vehicles, and the direction or angle of the vehicle is different. The normal data network is created for supporting the ground-based system, and the aerial vehicles can be in the shadow if they are flying over some areas.

The supporting- or relay stations of the network are normally in the places, where is straight visibility to the ground. But to the air is limits. If the station is below the eaves, the metal structure can cover the drone, which flies in the line where is a metal structure in the straight line between the support station and drone. When we are thinking about the possibility to control drones from another side of Earth by using civilian internet that is possible.

But in this case, the drone must equip with the program, which allows it to look for the signals independently if the network signal is gone. Or the drones can work in pairs or groups, where one drone is always keeping contact with the network, and then that drone would deliver the control signals from the internet to other drones.

There are many problems with that kind of thing. But if the quadcopters would be equipped with TERCOM and DSMAC-type systems, they could operate independently in the city areas. In this case, the aircraft or satellite can create the 3D-map image and the drones can use Lidars or other types of systems to observe the area.

Drone swarms and intelligent inertial systems

Some of those drones might be equipped with gyroscopes or inertial navigation systems. That system would record the track, and then it would fly back to the position, where it had last time the control signal. when we are thinking about the intelligent inertial system, the system needs only the gyroscope. And the other data that the system needs would get from propellers.

The system simply calculates how many times the propellers have been rotated during the time unit, and then the system would just fly back the movements, what it has taken. And then the computer just rotates the propellers as many times as it has been rotated during that distance.

So there is not necessarily needed the acceleration sensors at all. The acceleration sensor would be ineffective if it is used in the low-speed flight. But if we are using a laser-based system, what meters the range to the walls and other barriers, that kind of system can calculate the acceleration very effectively even in the low-speed flying.

Lidar is a very good tool for that purpose because it can use as the altimeter. But also normal, small size radar or sonar, what is similar, what is used in the mobile telephones for focusing cameras can be used for that thing. That system can also scan the ground and buildings.

Multiple sensors guarantee the success of the mission, but every drone must not have the same kind of sensor pack. And artificial intelligence makes those swarms very flexible.

The CCD-cameras can look at the environment by using the normal, and infrared frequencies. And those drones can also connect their computers to one bigger entirety, which makes it possible to connect their capacities to run those programs. The drones can also communicate with the satellite by using the GPS and satellite communication sets.

The thing is that only one drone must have the satellite communication set with a high-speed modem. That is so-called "master drone", what would deliver missions to the other and simpler drones. The thing is that the master drones would observe simpler drones, and if some of those "slave drones" would be lost contact, the master sends the relay drone to see, what is happening.

So, in this case, the drone swarm might have many types of members. Only a couple of members have all systems, and the others, what is operating in the "danger zone", where they can be damaged might be simpler. And those simpler drones might be located by using RFID-based triangular metering systems. That helps to keep the price of those systems lower.
