Various Jamming technology works

result of wireless transmission system stability. When the indicator is lower than the minimum system requirements, communication can not be normal. Whichever jamming technology, the jamming principle is the same, is to deteriorate the signal-to-noise ratio of the communication system SNR, the receiver can not resolve the correct data, resulting in normal communication can not be achieved in order to achieve interference purposes. Now on the above three commonly used technology to analyze the working principle of each jamming technology works as follows:

1, Analog VCO interference technology working principle:
Analog VCO, also known as a voltage-controlled oscillator, exerts an external fixed voltage and can produce a voltage corresponding to a certain RF frequency of the CW signal, commonly known as a point-frequency signal. When the external voltage changes continuously, it is possible to output a CW signal whose frequency changes continuously.
Using VCO interference technology, commonly known as swept interference. The VCO output continuously changes the radio frequency signal, with the interference frequency collision, causing the communication system the SNR deterioration, thus realizing the disturbance goal.

2, DDS interference technology works:
DDS is a direct digital frequency synthesizer, from the physical sense, DDS is a digital discrete analog VCO. The interference mode and the analog VCO are the same. But also by sweeping the way, and the interference frequency collision, in order to achieve deterioration of the communication system SNR .

3, (FPGA jamming technology) pseudo-random number Gaussian white noise interference technology works:
Through digital encoding, the FPGA, makes a certain bandwidth of the noise signal. Making the whole communication system full of noise within the bandwidth, deteriorating of the communication system SNR, to achieve their goals.

FPGA (Field-Programmable Gate Array) based digital jamming technology has several advantages over traditional analog jamming techniques, including:

  1. Programmability: FPGA allows for fast and flexible reconfiguration of jamming signals, making it easier to adapt to changing threat environments.
  2. Precision: Digital signals generated by FPGA can be precisely controlled and fine-tuned, leading to more efficient and effective jamming.
  3. Efficiency: FPGA can perform multiple jamming functions simultaneously, making it possible to target multiple threats with a single device.
  4. Integration: FPGA can be integrated with other digital signal processing components, leading to more compact and cost-effective jamming systems.
  5. Reliability: FPGA is less susceptible to noise and other environmental factors than analog systems, leading to improved reliability and reduced maintenance costs.

Advantages and Disadvantages of Three Common jamming technology

1, Analog VCO technology:

  • The design is simple
