Area of Science:

• Aviation Safety
• Optical Detection Systems
• Aerospace Engineering

Background:

• Collision avoidance remains a critical challenge in aviation.
• Existing detection systems have limitations in range, accuracy, and cost.
• Need for advanced systems to determine threat aircraft parameters simultaneously.

Purpose of the Study:

• To develop and evaluate a laser beacon collision hazard determination system.
• To assess the system's capability in determining range, bearing, and heading of threat aircraft.
• To analyze the system's performance under various visibility and altitude conditions.

Main Methods:

• Utilizing laser beacon technology for simultaneous measurement of range, bearing, and heading.
• Performing calculations to determine detection ranges under different visibility conditions.
• Simulating scenarios to evaluate warning times for aircraft at various altitudes.

Main Results:

• Threat aircraft detectable at over 10 km in good visibility.
• Warning times exceeding 15 seconds for aircraft below 3000 m in 5.6 km visibility.
• Accurate range measurements demonstrated under daylight conditions.
• System handles traffic saturation due to distinguishable signals from closer aircraft.

Conclusions:

• The laser beacon system offers a viable solution for real-time collision hazard determination.
• The system provides adequate warning times for enhanced aviation safety.
• Flexibility in system selection based on operational requirements is possible.
• Further development and testing are warranted for operational deployment.
