A Reasonable Alternative System for Searching UAVs in the Local Area

Area of Science:

• Aerospace Engineering
• Signal Processing
• Navigation Systems

Background:

• Professional Unmanned Aerial Vehicles (UAVs) operate in challenging environments, risking mission termination or loss.
• Existing distress locating systems are unsuitable for specialized, high-value drones.
• Locating crashed UAVs in unknown or hostile territories presents a significant operational challenge.

Purpose of the Study:

• To propose an innovative terrestrial localization system for crashed professional UAVs.
• To develop a direction-finding system independent of standard GPS or coordinate-based methods.
• To enable UAV location in "enemy" or inhospitable territories using reserved frequencies.

Main Methods:

• Design of a terrestrial localization system utilizing Doppler effect principles.
• Processing and correlation of received distress signals.
• Development of an innovative targeting system (IDVOR) based on VHF distress signal broadcasting.

Main Results:

• The proposed IDVOR system successfully determines the direction of a crashed UAV.
• The system operates independently of traditional positioning systems (e.g., GPS coordinates).
• Effective localization is achieved even in challenging "enemy" or inhospitable territories.

Conclusions:

• The IDVOR system offers a novel solution for locating high-value, specialized UAVs after a crash.
• This Doppler-based approach provides crucial directional information in environments where standard navigation fails.
• The system enhances UAV operational safety and recovery efficiency in critical scenarios.
