III. Detailed Explanation of the Lightning Localization Early Warning Core Functionality

3.1 Real-Time Radar Monitoring (Core Feature)

Real-time radar monitoring is the core functionality of this system; it employs an industry-leading eight-part partitioning architecture to enable precise lightning location tracking and visual representation.

80% structural design

The Lightning Localization System innovatively employs a 24-zone division scheme (8 directions × 3 distance ranges), dividing the monitoring area into 24 distinct sectoral zones. Each zone independently displays the lightning status, with the color dynamically changing according to the lightning risk level, providing an intuitive visualization of lightning distribution. Compared to traditional circular radar charts, this design enables more precise localization of the lightning source’s direction and distance, offering users more accurate decision-making support.

Visualization of Three-Tier Risk Levels

The system plots three concentric circles on a radar chart, each representing the distance boundaries for overhead lightning, nearby lightning, and distant lightning, respectively. These circular distance thresholds can be customized according to specific requirements; the default values strictly comply with the industry standard for the YBY-SD35 device (9.26 km/18.52 km/55.56 km), ensuring the accuracy and reliability of the data.

Lightning Gradient Fade Effect

The Lightning Marker uses a gradient fading effect on the radar chart – transitioning smoothly from fully opaque upon appearance to transparent disappearance – to visually represent the temporal characteristics of lightning events. The duration is configurable (default: 15 minutes); if a new lightning event occurs within this configured time frame, the area’s color will be updated accordingly, enabling users to stay informed about the latest lightning activity in real time.

Polar coordinate precise positioning

The system employs a polar coordinate conversion algorithm to precisely translate lightning distance and directional data into coordinate positions on the radar display. It achieves distance accuracy within the 10-meter range and directional accuracy of 1 degree, ensuring the precision of lightning location data.
