Description

A long-wave signaling system based on air platform

technical field

The invention relates to the field of long-wave signaling, in particular to a long-wave signaling system based on an air platform.

Background technique

Long-wave communication refers to a means of communication using radio waves with a wavelength of 1km-10km, and the corresponding frequency is 30kHz-300kHz, also known as low-frequency communication. Its biggest feature is that the radio wave propagation is relatively stable, the propagation attenuation is small, and it can go deep into seawater and underground with a small loss. It can be widely used in ocean communication, underground communication and geological exploration. The existing submarine communication is mainly based on the shore-based long-wave signaling system. The existing shore-based long-wave signaling system has a large scale, a long construction period, a huge cost, a small number and is difficult to conceal, a fragile structure, and it is difficult to repair in a short period of time if it is damaged, and its persistent performance is poor; there are four ways to improve the persistent performance Types: Concealment, Ruggedness Against Hard Attacks, Mobility, Number. The radio signaling system needs to radiate electromagnetic signals to the outside, and cannot adopt a concealed and robust method to achieve persistence. Therefore, the submarine signaling system can only rely on the maneuverability and the number of signaling systems to achieve persistence. It is necessary to develop a submarine signaling system with maneuverability and low cost that is suitable for a large number of equipment.

On the other hand, starting from tactical communication, due to the lack of direct and effective command means for submarine formations to submerged submarines, the coordination between formations and submarines cannot be truly implemented. When the submarine is assigned to the surface ship formation to cooperate with it, the ship formation generally transmits the letter through the shore station, but there are many command links, which will restrict the submarine's maneuverability, the shore station needs to be prepared for a long time, and the equipment consumption is large, which makes it difficult to send the letter in real time. . At the same time, if the command of the formation to the submarine is transferred through the shore station, there will be problems such as low timeliness, limited depth, and inability to guarantee the ocean waters, and it will occupy limited communication resources. letter means. To sum up, it is necessary to improve the existing long-wave signaling system.

In order to solve the above problems, the present invention provides a long-wave signaling system based on an aerial platform. The long-wave signaling system of the aerial platform includes: an aerial platform, a pod long-wave signaling subsystem, and an antenna, wherein the aerial platform and the pod long-wave signaling One end of the subsystem is connected, and the other end of the long-wave signaling subsystem of the pod is connected with the antenna; the long-wave signaling subsystem of the pod includes a control unit, a long-wave power amplifier unit, a retractable hoisting device, and a power supply device, wherein the power supply device passes through the power supply wire They are respectively connected with the long-wave power amplifier unit, the control unit, and the retractable hoisting device.

The power supply device is responsible for supplying power to the control unit, long-wave power amplifier unit, retractable hoisting device and other parts. In addition to the function of long-wave power amplification, the long-wave power amplifier unit also has the function of tuning and matching of output signals. The feeder in the antenna mainly plays the role of transmitting long-wave radio frequency signals, the antenna body mainly plays the role of radiation, and the terminal stabilizer ensures that the antenna is in an approximately vertical state. The antenna is connected to the retractable hoisting device in the long-wave signaling subsystem of the pod. As the height of the aerial platform increases, the electrical size of the antenna increases accordingly. Due to the increased electrical size of the antenna, the radiation efficiency of the antenna system is improved.

Further, the antenna is suspended. The antenna can be tuned and matched by controlling and changing the height of the aerial platform and the length of the antenna, thereby changing the input impedance of the antenna itself accordingly.

Furthermore, the pod long-wave signaling subsystem adopts the form of a pod mounted on an aerial platform. It is characterized by small size, light weight, and good electromagnetic compatibility. It can be carried and transferred by maritime combat platforms such as carrier-based aircraft, drones, and balloons.
