Stealth Sensors for Unmanned Aerial Vehicles (UAVs)

Since WWII, air superiority has increasingly shaped warfare outcomes. To maintain dominance, nations have heavily invested in aviation, with UAVs emerging in the 21st century due to their low cost, ease of deployment, and no pilot risk. Widely deployed for attack and reconnaissance, UAVs offer clear advantages over manned aircraft but face challenges like short range, low altitude, and poor maneuverability, making them vulnerable to radar detection and attacks.

To enhance UAV survivability and penetration, two main anti-radar technologies are used: passive stealth and active jamming. Passive stealth reduces radar cross-section through design and materials but is frequency-limited. Active jamming equips UAVs with systems that detect radar signals, analyze them, and emit deceptive or disruptive radio waves, weakening radar effectiveness and improving UAV protection.

Active Jamming Technology for Unmanned Aerial Vehicles (UAVs)

• The active jamming device supports a wide frequency range (covering S to X bands, or customizable to wider bands), enabling it to counter most air surveillance radars.

• It operates intelligently without the need to pre-identify enemy radar frequencies or positions. In complex electromagnetic environments, it can autonomously identify threats, make decisions, and carry out effective jamming to protect the UAV through active stealth.

• The device is compact and offers flexible installation options. Its modular design allows for easy debugging, installation, removal, and replacement.
