Description
Technical Field
[0001] The present invention relates to the technical field of anti-aircraft vehicles, and in particular to a wide-band navigation deception, suppression and interference integrated system based on optical microwave technology. Background Art
[0002] The target is an unmanned device or manned aircraft that uses radio flight control signal equipment and self-contained program control devices. With the rapid development of the target, its application in military and civilian fields has greatly expanded the use of the target.
[0003] At present, the means of defense against targets are mainly divided into air defense missile attack, laser damage strike, capture network capture and radio signal interference. The existing navigation deception systems and methods are:
[0004] The patent (CN117741704A) published in 2024, "An unmanned drone detection and deception system", uses an omnidirectional detector to locate the target, then lures the target to land at a designated location and can replace human supervision in some scenarios.
[0005] The patent (CN115755099B) published in 2023, "A distributed navigation deception system and method for anti-interference drone countermeasures", sends instructions through the central control unit to control the aircraft group to evenly distribute and surround the target, and then implements navigation deception on the target.
[0006] The patent (CN113985461B) published in 2021, "A drone detection, deception system and method", receives three navigation signals from Beidou, GPS, and GLONAS, calculates and processes the decoy signal through an algorithm, and then uses a multi-frequency gain antenna to transmit the decoy signal.
[0007] At present, the publicly reported literature on navigation deception, suppression and jamming systems all use single-frequency or multi-frequency technical solutions. However, the types of target aircraft that can be defended by single-frequency or multi-frequency systems are limited. On the contrary, the use of wide-band technical solutions can greatly increase the types of target aircraft that the system can defend. However, there are currently no systems and methods involving wide-band systems and methods, but practical applications urgently need wide-band systems and methods.
[0008] In summary, there is currently no public literature regarding the integrated wide-band navigation deception, suppression and jamming system. Summary of the invention
[0009] In view of the deficiencies in the prior art, the present invention provides a wide-band navigation deception, suppression and interference integrated system based on optical microwave technology.
[0010] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0023] The pulse driving source provides voltage to the high-energy pulse cluster fiber laser to ensure that the high-energy pulse cluster fiber laser can operate normally;
[0024] The high-energy pulse cluster fiber laser comprises a high-frequency modulation module and an optical power amplification module. The high-energy pulse cluster fiber laser outputs high-energy laser pulses with sub-pulse frequencies continuously tunable from 0.5 GHz to 10 GHz to a photoconductive semiconductor switch;
[0025] The photoconductive semiconductor switch outputs a tunable microwave signal with a frequency of 0.5 GHz to 10 GHz consistent with the incident laser pulse parameters to the radiation component according to the voltage input by the pulse driving source and the laser pulse input by the high-energy pulse cluster fiber laser;
[0026] The radiation component is used to transmit microwave signals to intercept and interfere with targets.

[0039] S3. The radio monitoring subsystem monitors, receives and analyzes the flight control signal of the target, thereby obtaining the target's position information; the main control system determines whether the target is within the system's jurisdictional airspace according to the jurisdictional airspace range set by the system and the target's position information. When the target is within the jurisdictional airspace, the verification result is determined to be "true", and the main control system issues a control command to the interception interference subsystem and the navigation deception subsystem to start the interception interference subsystem and the navigation deception subsystem; when the target is not within the jurisdictional airspace, the verification result is determined to be "false", and the main control system determines that the target's position information is a false alarm, and deletes the target from the radar detection subsystem;
[0040] S4. After the interception and jamming subsystem and the navigation deception subsystem receive the control command, the interception and jamming subsystem emits a microwave signal to interfere with the target's flight control. At the same time, the navigation deception subsystem sends the generated navigation deception satellite signal to the target to complete the target disposal.
