UAV Detection Jamming System Description V1.0

Function Description of Each Module of the System

1. Log-periodic Antenna_1

Band frequency: 25 MHz - 6000 MHz. It is responsible for the transmission and reception of radio frequency signals. It can radiate the processed signals into space (for transmission), and also capture the radio frequency signals in space (for reception), achieving the "air interface" between the signal and the outside world.

2. RF Switch

Used for switching the RF signal path, it enables flexible selection of the signal transmission route. For instance, under different test modes and interference strategies, the signal can be directed to different processing modules, antennas, etc., thereby achieving flexible configuration of the system functions.

3. Amplifier Set1

Amplify the radio frequency output signal to enhance the signal strength, ensure that the test signal can reach the expected coverage range and power level, and optimize the quality of the transmitted signal.

4. LNA1

Perform pre-amplification on the received signal of the antenna to enhance the signal-to-noise ratio, enabling subsequent signal processing modules to handle the signal more clearly and accurately. This is commonly used to improve the reception of weak signals.

5. Log-periodic Antenna_2

Band frequency: 400 MHz - 6 GHz. This part is responsible for transmitting the radio frequency signals generated by the system (such as interference signals, test signals) into space to achieve spatial coverage of the signals and act on target devices (such as unmanned aircraft).

6. Amplifier Set2

According to the interference requirements, the radio frequency signal is amplified to increase its power, ensuring that the interference signal or test signal can reach the expected coverage range and power level, and meeting the signal strength requirements for scenarios such as "interference (Jamming)".

7. LNA1

Perform pre-amplification on the received signals of the antenna to enhance the signal-to-noise ratio, enabling subsequent signal processing modules to handle the signals more clearly and accurately. This technique is often used to improve the reception of weak signals.

8. Log-periodic Antenna_3

Band frequency: 400 MHz - 6 GHz. Specifically designed for receiving radio frequency signals, it can accurately capture signals within a specific frequency range, providing input for the signal detection and analysis module. It is commonly used to enhance the reception capability of target signals.

9. SDR_8T8R

The SDR's 8T8R board card is used to complete the signal detection and processing functions. It mainly includes the signal generation module, the RF signal switch control module, and the receiving signal processing module (signal detection and analysis). The channel control module (which can distribute the generated or processed signals to different antennas, detection devices, etc., to meet the requirements of multi-channel and multi-target signal applications). It has the function of broadband signal detection and analysis, which can detect parameters such as the frequency, power, and modulation characteristics of the signal. At the same time, it can be used as an excitation source to output specific signals, for signal quality detection, characteristic analysis, and system performance verification.

10. Reinforce Computer

As the "brain" of the system, it enables remote control, parameter configuration and process management of the entire RF system. By communicating with the SDR board card, it allows setting the parameters of the signal generation module, controlling the RF switch paths, accessing the detection and analysis functions, and presenting the system status and signal data, making it convenient for operators to manage the system operation.
