Drone jamming

Project Title

Drone jamming

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

The project is to design jammer that block the frequency of ISM band. The idea is to make a frequency jammer that disrupts ISM band frequency especially for drones. In recent years, drones have undergone tremendous development. Due to the low price and ease of use, drones have been widely utilized in many application scenarios, which potentially pose great threats to public security and personal privacy. To mitigate these threads a jammer is required that block  remote control signal to protect our privacy and personal space.

Project Objectives

• Commercial drones has raised a privacy concerns among citizens since most of the drones flies equipped with high quality cameras which can invade people privacy, taking photo of people and personal property.
• Our objective is to design a jammer that locate the UAV and jamm it and prevent the pilot from breaching privacy.

Project Implementation Method

In this design we will block the most commonly used
remote control R/C communication link 
Common R/C frequencies:
Band 1: 2.4 MHz – WIFI g/b/n: ? 2.4 – 2.5 GHz
Band 2: 433 MHz ISM Band: 433.05-434.79 MHz

The design includes two band Jammers . The RF circuit will consist of voltage controlled oscillator to sweep the required band along with tuning circuit to drive the VCOs also it will include a linear power amplifier to amplify the output power of the VCO. Tuning circuit will consist mainly of saw tooth generator to generate the tuning signal along with noise generator to tune the VCO to the required RF Jamming signal. Last but not least power supply circuit is designed to provide the required DC voltages for the RF and the tuning circuits from alternating 220/110 power input.

Benefits of the Project

• It prevents  communication between visitors and inmates.
•  it is  utilized in places like airports . As a result, having a jammer can help in increase security as drones can be used to smuggle drugs, crashinto buildings, act as peeping Toms, drop bombs, shoot guns,and gather personal data on anyone whom drone pilot want to harm. Hence a Jammer to block drones remote control signal.
• Due to the low price and ease of use, drones have been widely utilized in many application scenarios, which potentially pose great threats to public security and personal privacy. To mitigate these threads a Jammer that block  remote control signal to protect our privacy and personal space is required.

Technical Details of Final Deliverable

The maximum power of ISM Bands allowed for civilian
drone is 36 dBm EIRP with maximum transmitted power of 1 W (30dBm) and theminimum Signal to Noise ratio SNR is 4 dB for data. Henceusing a simple arithmetic; the radiated power of the RFJammer must be more than 32 dBm EIRP

To achieve this required radiated power for Band 1 RF
circuits, two cascaded power amplifier with total gain of 30
dB is employed with 3dBm VCO output power and 7dBi
Antenna; the radiated power of Band 1 RF circuit is 40dBm
which exceeds the required Jamming power required to
block “band 1 (2.4 GHz)” civilian drone R/C communications.

For Band 2 (433 MHz) RF Circuit; a high gain power
amplifier is utilized with 35dB typical gain and 2 dBi
Antenna is employed radiating a total EIRP power of 37 dBm
which is more than the required Jamming power required to
Jamm “band 2 (433 MHz) civilian drone R/C
communications.
