[0025] The signal generator 2, power amplifier 3, modulator 7, oscillator 8, mixer 9 and detection antenna 10 in the device of the utility model work together to generate and transmit efficient interference signals, thereby effectively interfering with and blocking shortwave communications.

[0026] The generation and emission of interference signals can be flexibly adjusted and controlled by the signal controller 5 to adapt to different communication environments and interference requirements. The connection between the detection antenna 10 and the spectrum analyzer 11 enables the device to analyze the spectrum characteristics of the communication signal in real time, providing accurate data support for the generation of interference signals.

[0027] The use of the phase shifter 12 and the impedance matcher 13 can achieve accurate adjustment of the phase and impedance of the interference signal and improve the interference effect. The cooperation of the coupler 14, the isolator 15 and the impedance matcher 13 can effectively isolate and protect the circuit inside the device to prevent external signal interference and internal signal leakage.

[0028] The tripod 17 and folding plate 18 arranged on both sides of the outer shell 1 of the device of the utility model make the device easy to carry and install. At the same time, the design of the angle adjustment seat 21 and the bottom adjustment rod 22 allows the antenna frame 4 to flexibly adjust the angle and height as needed to ensure the stability of the device.

[0029] The utility model adopts modular design, and the connection between the components is simple and clear, which is convenient for maintenance and upgrading. This device that generates interference signals to counter shortwave communication has multiple beneficial effects such as high efficiency, flexibility, stability, and portability, and has important application value in protecting communication security and blocking illegal communications.

[0030] The utility model is started and initialized during use: when the device is started, the power supply battery 19 provides the required power to each component. The components such as the signal generator 2, the power amplifier 3, the modulator 7, the oscillator 8, the mixer 9, the detection antenna 10 are initialized and ready to enter the working state.

[0031] Signal generation: Signal generator 2 generates an interference signal of a specific frequency and modulation mode according to preset parameters or external control instructions.

[0032] Power amplification: The generated interference signal is amplified by a power amplifier 3 to ensure that it has sufficient power to be transmitted and effectively interfere with the target shortwave communication.

[0033] Signal modulation: The amplified interference signal enters the modulator 7 and is modulated with the carrier signal generated by the oscillator 8. The modulated signal has specific frequency and modulation characteristics to adapt to different communication environments and interference requirements.

[0034] Signal mixing and detection: The modulated signal enters the mixer 9 and is mixed with the signal from the detection antenna 10. The mixed signal is then detected by the detection antenna 10 to extract the required interference signal component.

[0035] Spectrum analysis and phase shift: The interference signal after detection enters the spectrum analyzer 11 to analyze its spectrum characteristics. According to the analysis results, the phase shifter 12 adjusts the phase of the interference signal to optimize the interference effect.

[0036] Impedance matching and coupling: The interference signal adjusted by the phase shifter 12 enters the impedance matcher 13 for impedance matching to reduce signal loss. Subsequently, the interference signal is coupled into the communication line through the coupler 14.

[0037] Signal isolation and transmission: The coupled interference signal is isolated by the isolator 15 to prevent external signal interference. Finally, the interference signal is transmitted through the interference signal transmitter 20 to interfere with the target shortwave communication.

[0038] Monitoring and adjustment: During the entire working process, the device will monitor the interference effect in real time and adjust the parameters of components such as the signal generator 2, the power amplifier 3, the modulator 7, etc. as needed to ensure the best interference effect.

[0039] The working principle of the device of the utility model to counter shortwave communication by generating interference signals is mainly to use the signal generator 2 to generate interference signals of specific frequency and modulation mode, and transmit them after amplification by the power amplifier 3. The interference signal and the target shortwave communication signal meet in space and generate mutual interference, thereby reducing the quality of the target communication or completely blocking the communication.
