Beginner's Guide to Counter-Drone Modules

1. How Counter-Drone Modules Work

Jamming modules generate a broadband, meaningless random radio signal—essentially "noise"—internally. This weak noise signal is then amplified significantly by a power amplifier, making its signal strength far exceed that of the normal remote control or navigation signals received by the drone.

2.. Classification of Counter-Drone Modules

NE555-based jammers: Generate a fixed-frequency square wave. When transmitted via an antenna, their rich harmonic components create interference across a broad frequency band. This is the simplest form of barrage jamming.

Digital source (e.g., LoRa) jammers: Generate frequency-controllable square waves, enabling simple frequency sweeping or pulse modulation. This makes them more capable and intelligent than NE555-based jammers.

DDS (Direct Digital Synthesis) jammers: A "digital-to-analog waveform synthesis" architecture. Frequency bands and power can be controlled via software, and sweep modes can be configured.

3. Applications of Counter-Drone Modules

Counter-drone jamming modules are widely used in RF soft-kill applications. Depending on the scenario, they can provide tailored solutions and are currently the most frequently employed technology in counter-drone jamming.
