Project Introduction

Airport bird‑strike prevention and control is no longer a matter of deploying individual devices; it now demands an integrated approach that prioritizes rapid target detection, high‑accuracy identification, efficient coordinated deterrent operations, and robust data‑driven analysis.
Traditional manual patrol methods offer limited coverage and delayed response, making it difficult to meet the modern airport’s requirements for all‑weather, full‑area, visualized, and traceable bird‑strike management.

The Sosk Bird‑Awareness Detection, Monitoring, and Deterrence System leverages bird‑detection radar, dual‑spectrum cooled thermal‑imaging pan‑tilt units, an intelligent analytics platform, and a range of bird‑deterrent devices to provide real-time insights into bird species, activity patterns, occurrence zones, and hazard levels. By generating heat maps, conducting trajectory analyses, enabling coordinated deterrent actions, and delivering annual bird‑management recommendations, the system helps users transition from “passive deterrence” to “proactive prevention and continuous optimization.”

I. Value of the Plan

1. Why is a bird‑detection, monitoring, and deterrent system necessary?

In the airport operational environment, avian activity exhibits the following characteristics:

• The activity areas are dispersed, with broad coverage.
• Flocking behavior occurs suddenly, and human detection is delayed.
• Different bird species pose varying levels of damage, making rapid assessment difficult.
• Bird‑related incident management often relies on experience and lacks data‑driven support.
• The outcomes of removal operations are difficult to quantify and assess, making it challenging to establish a long-term optimization framework.

Therefore, airports need not just to “see birds,” but rather a system capable of accomplishing… Timely detection, rapid identification, precise early warning, coordinated response, and long-term analysis. The complete system.

2. Operating Principle

When the bird‑detection radar identifies a suspected avian target entering a critical low‑altitude zone, the system automatically activates the dual‑channel pan‑tilt unit to swiftly slew to the target’s location for secondary confirmation and continuous tracking.
Upon completion of target identification, the system can transmit real-time information—including bird species, bearing, range, altitude, and trajectory—to the command and control center, and, based on the target’s threat level, trigger appropriate‑level alerts and recommendations for deterrence and removal.
For high-risk targets, the system can activate bird‑deterrent devices or other avian‑control equipment to take corrective action, while simultaneously recording the entire incident process to provide a basis for subsequent analysis and optimization.

3. Workflow

Step 1: Goal Identification

Bird‑situation detection equipment continuously scans key low‑altitude areas and, upon detecting suspected avian targets, outputs relevant information.

Step 2: Recognition and Tracking

The system‑integrated identification and tracking device locks onto, identifies, zooms in on, tracks, and captures snapshots of the target.

Step 3: Risk Assessment

The backend platform analyzes data based on target location, trajectory, species, time period, and regional characteristics to generate avian‑related alerts and risk advisories.

Step 4: Coordinated Response

In accordance with the preset strategy, the system coordinates with laser bird‑deterrent devices or other bird‑control equipment to carry out deterrent measures, and can also dispatch bird‑control vehicles to designated locations to stand by and drive away birds.

Step 5: Data Accumulation

The system stores and analyzes video, images, alarm logs, eviction records, trajectory data, and heat map information, providing a basis for continuous optimization.
