SONAR Target Tracking with Random Motion | MATLAB Bearing Rate Visualization Explained

Описание: In this MATLAB simulation, we explore how SONAR systems use bearing rate (the rate of change of the line-of-sight angle) to track and analyze multiple randomly moving targets.

A stationary SONAR observer (blue point) detects several moving contacts (colored targets). Each target continuously changes its direction and speed, causing its bearing angle and bearing rate (dθ/dt) to fluctuate in real-time.

When a target’s bearing rate approaches zero, its line of sight remains constant, a key indicator of a potential collision or intercept course (constant bearing, decreasing range).

This simulation visually demonstrates the principles used in naval SONAR, aerospace tracking, and autonomous navigation, where understanding bearing rate is essential for situational awareness and safety.

🎥 Inspiration: This project was inspired after watching “How Sonar Works (Submarine Shadow Zone) – Smarter Every Day 249.” Huge thanks to Destin and the Smarter Every Day team for sparking the idea to build a dynamic MATLAB visualization of sonar tracking concepts.
