Electronic Countermeasure System for Jamming

This project focuses on designing and constructing a compact portable electronic jammer operating in the 2.4 GHz frequency range which covers the bands for other technologies such as Wi-Fi or Bluetooth for wireless communication. The system architecture is based on ESP32 microcontrollers and nRF24L01 RF transceivers that are used to create signals that jam wireless communications in the specified frequency range. To increase the user-friendliness of the device, the microcontroller is supplemented with an OLED display that shows system status, in addition, the device is powered from a rechargeable battery with a TP4056 charge controller which allows using the device in the field. The device can be easily adjusted via Control buttons and signal antennas attached through SMA Connectors. This jammer’s main advantage is that it can be deployed while in motion for some electronic warfare systems mounted on transportable platforms like military vehicles, UAVs, or patrol drones. It's compact form and lightweight build allows for installation in limited-space environments without hindering mobility, system balance or performance. This makes it a practical solution for disrupting enemy communications to evade remote- controlled threats or disabling unauthorized surveillance drones during missions. This set of traditional systems will aim towards automating war functions in military approaches. The system’s adaptability is effective as it can easily jam signals of multiple targets concurrently, while traditional jammers fail to do so.
