Description

  The present invention relates to a radio interference system in which interference radio waves are transmitted from a radio interference device mounted on an aircraft to interfere with a radar wave of a counterpart aircraft.

In an electronic warfare system using an aircraft, the target radar wave escapes from the target detection, so the other party's radar wave is detected and a jamming wave is transmitted to the other aircraft, and the opponent's radar wave detection is disturbed. A radio interference device is installed on the aircraft.
In this way, when jamming radio waves are generated by a radio jamming device mounted on an aircraft, single jamming that generates jamming radio waves only from the own radio jamming device and both radio jamming devices in cooperation between the own aircraft and a wingman There are cooperative interference that generates jamming radio waves, and support interference that supports the aircraft by generating jamming radio waves only from the radio interference device of the wingman in cooperation between the aircraft and the wingman.

  A data link processor that detects the start and stop of transmission of jamming waves and creates a synchronization signal as a linked jamming device that transmits jamming waves in cooperation between its own aircraft and wingmen. The transmission timing of the jamming wave is synchronized by transmitting to the jammer of the wingman via However, since a dedicated data link device is necessary only for synchronization, a receiver that receives the interference wave transmitted by the wingman is provided, and the transmission timing, frequency, etc. of the interference wave that is transmitted are detected in real time. There has been known a cooperation disturbing device that performs synchronization disturbing with a simple configuration in which the data link devices are omitted by synchronizing them. (See Patent Document 1)

In addition, in the case of cooperative interference in which interference waves are transmitted between the aircraft and the wing aircraft, the radio waves received by the aircraft are the radar waves transmitted by the wing aircraft, and the other aircraft (threat aircraft) that is a threat by the wing aircraft. There are various types of radio waves such as a transmitted jamming wave, a jamming wave from a threat to a radar wave transmitted by the own aircraft, and a jamming wave from a threat to a radar wave transmitted from a wingman. It is necessary to remove unnecessary waves from these various radio waves and accurately detect the target radio waves, but from the radio wave specifications of the received signal detected by the aircraft, information about the input aircraft, and information about the wing aircraft 2. Description of the Related Art An electronic warfare system including an RF (radio frequency) management device that can remove unwanted waves is known.
This RF management device transmits information on the position of the aircraft, the radar transmission frequency, and the position of the threat aircraft detected by the aircraft to the wingman, while the position (latitude, longitude) of the wingman, the radar transmission frequency, and the wingman detect it. In order to receive information on the position of the threat aircraft being connected, it is connected to a data link device, and information is exchanged between the aircraft and the wing aircraft via this data link device.

  When jamming radio waves are generated only from the own radio jamming device, it is difficult to spatially understand the status of radio jamming transmission against the jamming target. Is difficult to grasp, and depending on the interference technology and means of interference, the direction information by the interference transmission may be detected by the interference target side, and the self-protection effect is not functioning at all. There was also a case.

Also, in the case of interfering interference such as patent literature, information sharing by data link is not carried out, and radio reception is attempted to be identified due to time restrictions. It is impossible to know whether the radio wave is a radio wave transmission of the jamming radio wave and the interference modulation by the reception determination by the wingman.
In addition, in the case of transmission of radio wave information when there is no real-time capability due to multiplexing and high-speed digital communication technology, the data link has a small amount of information to be linked, and the radio wave environment between the own aircraft and the wing machine is complicated (target radio wave) Or processing of information that can be distinguished, such as a wingman radio wave, was necessary, and the processing capability was insufficient.

  Even in support disturbance, radio wave information encountered in a threat environment depends only on spatial reception activity, and if it cannot be received, support disturbance could not be implemented. In addition, the assistance disturbance could not be diverted to a high-power disturbance device using a ground radar device based on the airspace and radio wave information of the aircraft.

In the radio wave operating environment in recent years, in individual radio wave devices (radio wave receivers, radio wave jammers), obtaining target information with further accuracy and higher performance has reached the limit of improving technical capabilities.

However, with the spread of multiplexed data communication technology using digital data link devices, it has become a data transmission technology for communication devices. It has become possible to easily share data by superimposing radio wave information.

  The present invention is based on the cooperation of radio wave equipment and data link equipment (digital / data radio communication equipment), to grasp the status of radio wave interference by sharing radio wave reception and radio wave interference data information, and to make effective use of radar equipment. An object of the present invention is to provide a radio interference system capable of performing radio interference or support radio interference.

  As described above, the invention of the fourth embodiment is based on the fact that there is no means for confirming whether or not the disturbance radio wave is effectively spatially radiated in the support disturbance by the own aircraft 12. By being able to confirm by the display, it can be confirmed that the jamming radio wave is radiated in the space and the tracking is avoided due to the support disturbance.

Embodiment 5 FIG.
Although the fifth embodiment of the present invention is not shown, in the fourth embodiment, the wing aircraft 13 is used as a ground radar device or a ground jamming device, and jamming transmission of higher power is performed from the rear of the own aircraft 12. It is an example. Aircraft interference is usually transmitted over a wide coverage area, so power cannot be concentrated on the target, but the transmission beam should be concentrated from the ground onto the target to create a large support disturbance signal. And can be expected to have a blocking effect. In addition, when the radio wave is disturbed from the ground, it is a long distance, but since the radio wave reception information of the target aircraft 11 is obtained from the own aircraft 12 via the data link 3, the target aircraft 11 is not required to receive the target signal. On the other hand, only radio interference can be concentrated.
